Sessions? External Program / External Program
I am trying ac ouple of days now to learn some things on SESSIONS,but I think I am not getting it very clearly. I have a PHP page tha contains a form.
Users enter data in the form, which are then written in a file (the file is created at the time a user enters some data) The file is then given as an input to an external program The external program runs and gives some results which are then stored in another file (that is created when the external program finishes) What I want to do is to somehow create these files and, when the user exits from the browser, then both files that refer to this user, will be deleted. Code:

External Program Via PHP
I need to execute a command-line program through PHP. I have a form which includes a textarea, where the user writes his data. These data will be used as input for the commend-line program. Will I go something like: $data = $_GET['info']; Which function shall I use? System, exec, shell_exec, passthru? I can't choose which one is the correct. By the way, the command which I use when I write the script in the command line is : program_name [argument1 -> A database file] [argument2 -> info supplied by user] So, in the function that will be used, the data supplied by the user will be passed as my second argument (the 1st argument is a file in my hard disk). And, lastly, do I need to change any global settings for PHP in order to perform such actions, ie running scripts via PHP programs?

Opening An External Program
I was wondering if there was a way to be able to create a PHP program that when you click on a link or image on a webpage that it would automatically open up an application in the client's computer. I have a webpage that is sort of an 'engineering catalog'. Each item on that catalog is linked to a downloadable file. When a user clicks on this item, it should be able to open an engineering application, and pass the downloadable engineering file from the webpage into the engineering software application. Any ideas?

Exec() Call To External Program
We are trying to use the exec() or system() calls in a php script. The program we are trying to call takes 1 parameter in the form of: email@domain.com[usercode] There are no spaces in the parameter at all and we have tried placing quotes around just to see if it mattered. We have also modified the parameter just to send it hello. Here is what we get: With no parameters the php script executes the program where it displays the error message from the program stating that not enough parameters were supplied. We then add the word "hello" to the end after a space so the command looks like this: command "hello" and the program no longer executes at all. No matter what we do, if we supply an argument to the command the php code will not execute the program.

How Do I Make Sure That An External Program Does Actually Exists?
web host said there is a program /usr/bin/convert I can use to convert image files, after I call it in my code, it does not seemed to be doing anything. I'm sure the command line is right because I echo the commandline to make sure. How do I make sure that an external program does actually exists? I use if (file_exists "/usr/bin/convert")), is there any othe way? Or am I doing something wrong that the system call is not working? For example: //convert test.jpg to converted.jpg $command = "/usr/bin/convert "test.jpg" "converted.jpg""; echo $command; system($command);

Problem With Sessions / External Javascript Files In IE6 Only
I have a very frustrating problem. I have been trying to make it more difficult to access external javascript files by using PHP sessions. This works beautifully locally (both in IE6 and IE7) and online in IE7, but frustratingly, online in IE6, the javascript does not render on the page, unless you refresh the page. Is there something different about the way IE6 handles sessions? Why would it work locally but not online?

External DOMEntity's
I have a question about PHP5's DOM, but I found the docs on this section are either incomplete or incorrect (e.g. wrong return types for several functions). How can external entities, or entities in general, be added to a DOMDocument? (I'm not asking about adding entity references because DOMDocument->createEntityReference works like a charm.) I should probably state the details around the problem: I am working on a templating engine that utilizes PHP5's DOM interface (http://xire.forizon.com for details) so for caching purposes if I can make the output document include cached versions of other templates via external entities (XInclude is already used, but not it isn't supported very well on the client side), then any client-side caching can also be utilized.

Url In An External Php File

How can I write this code into the echo document.write function?

Getting External Data
I am logged in to Yahoo with my Yahoo ID, and I visit: http://baseball.fantasysports.yahoo.com with my browser, it will tell me which Fantasy Baseball leagues I am in, and allow me to click on one to enter the league page. I figured therefore, that if I were already logged in, that the following code, would display the same page (i.e. I would be able to see which leagues I am in): $remotefile=fopen('http://baseball.fantasysports.yahoo.com/','r'); while (!feof ($remotefile)) { $line = fgets($remotefile); echo($line); } Unfortunately, the resulting page asks me to sign in, and doesn't display the desired leagues. But I AM still logged in to Yahoo. If I were to try to visit: http://baseball.fantasysports.yahoo.com again in my broswer, it knows I'm still logged in and displays my leagues.

External Programs
I have just installed my first Linux distribution (SUSE 10.0). Everything is compiled as far as Apache, Mysql & PHP is concerned. But, I have this problem: I call system commands through PHP using system, shell_exec etc The thing is that PHP responds OK when it comes to 'ls' or 'grep' or 'wget', but, in another program, not UNIX-native, there is no response. I am sure that the program is set up in the PATH, because, if I open a terminal, I can call it from everywhere and it works fine.

Then it will continue to read the remainder of the file and repeat the process until it reaches eof. Is there something similar to goto or gosub, I did some checking and was laughed at, as you can probably tell I'm a newbie. Maybe I should be calling an external script.

How To Program OOP
I use OOP for a PHP Application Framework I am programming. I have one base class which includes all the necessary functions and variables which all the other classes use. So what I originally did was that I made an instance of the base class and passed it to the other classes. Now someone insisted that this is not the way to do it. so I used 'extends base' to make the base class available to the other classes. Afterwards it worked fine, but it didn't make the code smaller nor did it result in faster speed. I used the benchmarking script from PEAR. So I wonder whats the difference between those two solutions, both work fine. Are there some tools to analyse how much memory a script uses?

XML Form Post To External URL
I'm far enough along in PHP to know how to create input forms, grab the form input as $_POST variables, do some basic validation checks and present the errors to the user for resubmit if needed. For the life of me I can't understand why I can't post data as an XML document to one of my advertisers. For example, a lead form is complete with Name, Address, Phone, and so on. I capture the form data and submit as an XML document. This particular advertiser will only accept data as an "External XML Post." I tried using Javascript and PHP with cURL, but I'm going in circles trying snippets of other people's code -- it's been a week. At this point all I want to do is assume IE7 (nothing else!) and no data checks, just "here's the XML, here's the external URL" and show me that HTTP POST actually works. Right now I'm thinking it's a bunch of junk :-) Someone please help. Here's my server info: PHP Verion 4.4.4 Apache/2.0.46 (Red Hat) CURL support enabled CURL Information libcurl/7.15.4 DOM/XML enabled DOM/XML API Version 20020815 libxml Version 20510 HTML Support enabled XPath Support enabled XPointer Support enabled XML Support active XML Namespace Support active Here's a sample of XML, let's call it "data.xml" <?xml version="1.0" encoding="UTF-8"?> <DataFormSubmit> <individual id="12345"> <FirstName></FirstName> <LastName></LastName> <Address></Address> <Phone></Phone> </individual> </DataFormSubmit> POST XML document to URL on an external website for example: http://www.example.com/othersite/xml.aspx Response XML is equally simple. There is no mention of MethodCall, MethodResponse and Params like the books say, so please don't use those elements in your reply to me. There is mention of field requirements like "Text field" "255 character max" "Numeric" but I think this can be handled by the input validation scripts. I'm just trying to POST and get a response. I've received errors refering to "permission denied" "access denied" "object expected" but at this point I've edited my code so many times I don't know what's right or wrong any more. Here's one of my failed cURL examples: <?php // XML data as string $request = '<?xml version="1.0" encoding="UTF-8"?>' $request .= '<DataFormSubmit>' $request .= '<individual id="12345">' $request .= '<FirstName></FirstName>' $request .= '<LastName></LastName>' $request .= '<Address></Address>' $request .= '<Phone></Phone>' $request .= '</individual>' $request .= '</DataFormSubmit>' // Create Headers $header[] = "Host: www.example.com"; $header[] = "Content-type: text/xml"; $header[] = "Content-length: ".strlen($request) . " "; $header[] = $request; // Send using CURL $ch = curl_init(); curl_setopt( $ch, CURLOPT_URL, "http://www.example.com/othersite/xml.aspx"); // URL to post curl_setopt( $ch, CURLOPT_RETURNTRANSFER, 1 ); // return into a variable curl_setopt( $ch, CURLOPT_HTTPHEADER, $header ); // headers from above curl_setopt( $ch, CURLOPT_CUSTOMREQUEST, 'POST' ); // special POST with specified Content-type $result = curl_exec( $ch ); // runs the post curl_close($ch); echo $result; // echo reply response ?> And I tried a Javascript variations using code like xmlhttp = new ActiveXObject("Microsoft.XMLHTTP") but I'll save that for a followup post since this is getting long. Anyone out there doing external XML form post?

Formating External Text
I have a quick question about the formatting of external text files. I am trying to make a webpage for a local church that will display what is on in the coming weeks. I have done this using an external text file so that the future users will never have to modifiy the page itself. If left as plain text, it shows on the page in default format. I know I can format the text within the text file using standard HTML, but is there a way of formatting regular text outside of the text file? Kind of post processing it? The file format will always be something like Monday 19th 09:00 Add event here 12:00 Add event here Tuesday 20th 09:00 Add event here 10:00 Add event here 13:00 Add event here etc... The number of events on each day is variable, and not every day may feature (could be monday events then thursday events). I would like to make the Day and date bold, the times italic...well you get the idea! I have an idea that I will need to impose a structure on the file, however I am unsure of how to do this. If this is the case, then I would appreciate it if someone could post a link to a decent tutorial or guide so I can learn it!

Including External File
I have two sites that I am trying to get to "talk" to each other. I have one site that contains a PHP file that basically outputs an XML formatted list depending on the file structure in that directory. The other site needs this XML formatted data to complete the PHP generated XML file that I am trying to put together. (Much like syndicating my content from one site to another) I have tried using readfile, include and header(Location:) and none of them seem to be working. What I need is for the calling file to somehow include the output of the remote file. (The same stuff you see if you view the source) What happens is that I can 'readfile' my index page on that site, but not the one that puts out the XML data that I need. Could it be that the XML file doesn't actually create any visual content on the page? or doesn't have 'head' and 'body' tags? It would be great if I could do all of this in PHP so that the final source would not include anything that would disrupt the final XML output.

Hopefully there are some experts out there that can help with this - I've done a bit of searching here but haven't found an answer yet. The problem is, the site where I'm hosting a set of html files does not support PHP. I have another host which does support PHP. I need to have my html files located on the server which does not support PHP. Is there some way I can execute my PHP scripts within a regular HTML file? I've seen references to using Javascript for this but no working examples (and none I could make work). Unfortunately I can't get PHP on the site where I need it without redirecting my domain (among other things). If there is a way to execute the PHP remotely, that would be the preference..

How To Invoke External Php Script ?
when a web request comes to my index.php, i would like index.php to execute a php script stored in an external file and capture the external script's output to a variable. i am doing this because the external script can read the database and can emit xml that i want to use. index.php (or whatever) wants to grab this xml and pass it through an xslt. i know that if the external php script had a function declared, and the function returned a string value with the xml contents, then i could use "require" or a similar construct and call the function. the question that i am trying to answer is what to do if the external script uses echo() to output the results? how to capture its output during request processing? besides, i do not like spawning another process for that and piping to it. it might not scale well. ;-)
