Require_once(<html Fragment File>) Vs Document.write(<html Fragment>)
To reuse common fragments of html on many pages I have used javascript functions, called from a linked .js file, which are precisely one instruction: document.write(<the html>).
I'm starting to learn PHP now and see that a require_once(<url for file containing the html fragment>); will have the same affect.
My question is, which method is more efficient? i.e. renders faster?
P.S. is there a simple way to set up testing-only server-software on my local machine so i can debug php locally before uploading them to site's server?

URL Of Referring Html Document
I am using this code to retrieve the current URL: function selfURL() { $s = empty($_SERVER["HTTPS"]) ? '' : ($_SERVER["HTTPS"] == "on") ? "s" : ""; $protocol = strleft(strtolower($_SERVER["SERVER_PROTOCOL"]), "/").$s; $port = ($_SERVER["SERVER_PORT"] == "80") ? "" : (":".$_SERVER["SERVER_PORT"]); return $protocol."://".$_SERVER['SERVER_NAME'].$port.$_SERVER['REQUEST_URI']; } function strleft($s1, $s2) { return substr($s1, 0, strpos($s1, $s2)); } which returns the URL of the current PHP script. But, I would like it to return the URL of the html page that preceeded this script. I mean, I have a some html pages with some photos. I have a form that allows users to enter an email address that will then send the link of that html page to the email address used. When I use the above it only shows the address of the page that executed the command, not the original html document.

Saving A Html Document
Currently my php produces a bill which my users can read but this is a dynamic php document and it works fine until a whole month goes by and they are a bit slow in paying. The next time they view the page it has two months quantity on instead of the one and I have got round it but I would prefer to have one bill per month. Could I save the html file (without any php) that is output into a file which could rest on the server until called? I have been trying to do this with a @copy($file, $path.$newfilename); but on reading other entries in this form I am wondering whether an fput would be better ... and what is the difference?

Remove All The White Spaces In Your Final HTML Document.
When you are coding in HTML or CSS, you want to remove all the white spaces in your final HTML document. All the spaces, carriage returns, tabs etc. The white space is just "noise" and is not displayed by the browser. Removing it will not have any impact on what is shown in the browser. Reducing white space will make the filesize a lot smaller, be quicker to download for your visitor, be take up less bandwidth when your site is crawled. It increases the content:markup ratio, which is good for SEO purposes. Code:

Upload Photo / Write To Html
I've been looking for a script -- PHP or Perl -- that will allow a person to upload a single photo via their browser and write the photo <img src> on the fly to an html page. There are of course many gallery type thumbnail scripts, but it's been nearly impossible to find one that will do the following after the user arrives at the script's online form page: -- first they give the html page a unique name, ie, vacation.html -- they next type in some text describing the photo that will be seen at vacation.html -- then they navigate to the photo on their harddrive via a "Browse" button -- click submit ==> the photo is uploaded and a page is generated called vacation.html with some text and the picture. Ideally such a script would have a config file that would allow the site owner to identify exactly which folder the images will go into; which folder will hold the html pages; the images could be of varying dimensions however a limit could be put on the maximum file size of each photo (for ex, 1 MB); only .jpg, .png, or .gif files would be allowed; and an option could be selected as to whether to permit overwrites.

PHP Does Not Write Full HTML Code Randomly
When writing an HTML table after a PHP database query very occasionally (1 out of ten times -- same code) the HTML page is truncated and cells/or full final rows of table are missing. Looking at the page source the code is truncated at some final point at the end. I load records in an array through a loop and then use another loop to render the html with embbeded php array variables to draw the html table. I thought this could be related to cache or may be solved using flush function?? I come from ASP and never happened in ASP code.

How To Read And Write Into A Word Document
I am working on a recruitment site and in that we have an option of cv upload. Either text, or word couments (.doc or .rtf) are allowed. I am able to upload the file successfully, but when I try to read that file and try to show in a textarea field I see some junk characters also getting displayed. Can anyone tell me what function should I use to suppress that junk and show only the text? What I am doing is open the file in read mode, read the entire contents of the file and display it.

P3P Compliant, Still Can't Read/write Cookies From IFRAME As 3rd Party Document
I have two sites, both with valid P3P policies that passed the W3C P3P validator, including the P3P compliant HTTP headers test. On one of the sites, Site A, I have a web page that loads a document from Site B in an IFRAME. In this context the web page on Site A is the "originating" document and the web page on Site B is a 3rd-party document (since it's from a different domain). I thought that having a valid P3P policy would make IE6 in the default Medim setting, allow cookies from my IFRAME document from Site B, but apparently it still does not. I am getting the dreaded "red-eye" and the document from Site B can't read/write cookies while in the IFRAME. Is this correct, that you can't read/write cookies from an IFRAME as a 3rd party document, even if you have a valid P3P policy that indicates no PII (Personally Identifiable Information) is collected? Or can I fix this somehow?

.html' Page Be Replaced By '.html.php'
Can a '.html' page be replaced by '.html.php' page via RewriteRule? To clarify, I'm using a software that formats the look of the site using .html pages. I'd like to add PHP code to that page but of course, it is not of the right page type. What I was wondering is Could I create a duplicate of that '.html' page, rename it to .g. '.html.php' and make the revisions and then just create a RewriteRule that redirects the '.html' page to the '.html.php' without generating an error? The alternative and undesired way of doing it would be to rename the original page to '.html.php' and find and revise ALL of the routines that call that page. That would create a revision nightmare especially upon upgrading the software.

Why No [fragment] In Parse_url($_SERVER['PHP_SELF'])?
I'm trying to identify which named anchor is currently being viewed on a page. Although the address bar of my browser shows #whatever appended to the end of the url, I can't seem to find it in a variable. My efforts below return no value for ANYTHING except [path]. Am I missing something? $url = parse_url($_SERVER['PHP_SELF']); $scheme = ($url[scheme]); $host = ($url[host]); $port = ($url[port]); $user = ($url[user]); $pass = ($url[pass]); $path = ($url[path]); $anchor = ($url[fragment]); echo $scheme." = scheme<br>"; echo $host." = host<br>"; echo $port." = port<br>"; echo $user." = user<br>"; echo $pass." = pass<br>"; echo $path." = path<br>"; echo $anchor." = anchor<br>";

.doc To .txt/.html?
Hi everyone, I'm making a site where people can upload articles, that are then stored in a mySQL db. The problem will come, of course, when people want to upload Word documents. Which they will. Is there any way in PHP of turning the .doc file into a .txt? Or even better, a html file with any formatting (bold etc) intact? A problem I have with my current site, on a related note, is that when people cut and paste from a word document into the form field, then submit it to the db, the resulting text is displayed with non-valid ASCII characters, which the w3c validator chokes on. I'm pretty sure there is a function that converts them, but a search of the manual didn't bring it up. I'd really appreciate any help you can give me...

HTML 2 PHP
I'm trying to convert my site from html to php. Instead off having to write seperate html files I want to insert my files in a kind of template file (index.php). I know that the include() function can do that so I have links in the form of index.php?file=whatever.php, but i don't want directly link to my files directly but i want to user variables for that. so my url will say index.php?file=variable or something. Can I set variables in my index.php so he checks for that variable and replaces the $file with that variable? So if my variable is $foo='anypage.php' that my url will say index.php?file=foo instead of the real filename.

--PHP To HTML
if that's the case, please just tell me where the best place for a newbie PHP question would be. I'm just learning PHP, and I need to know how to pass data from an HTML input form to become the content of a new HTML page, using PHP. In other words, I have an HTML page that lists parenting program information, thus: PROGRAM 1 Start Date: Aug 5 End Date: Dec 5 Time: Every second Thursday, 11:00am to 1:30pm Location: X Building Duration: 12 weeks Capacity: 10 parents PROGRAM 2 Start Date: Aug 7 End Date: Oct 14 Time: Wednesdays, 6:00pm to 9:00pm Location: Y Building Duration: 10 weeks Capacity: 15 parents, up to 30 children There are about 15-20 programs being offered at any given time, and they're constantly being added, deleted, and changed, so it's too hard to update them manually myself. What I want to do is: 1) Design an HTML input form on an intranet page that will allow users to add, change, or edit program data based on the fields listed above. I know enough HTML to do this. 2) Take that data and pass it to a new HTML file that will be available to the public, called "Our Program Info", which will list all the program info. I did try to RTFM to figure out step 2; but the manual is so large, and I'm so bad at programming in general (the only reason I'm doing this is because my wife runs the charity organization that this is for), that I couldn't find the right place to look. If someone could (gently) nudge me in the right direction,

Php To Html?
I urgently need to develop a site with around 30-40 pages. The site must be multilingual. Usually I use a top.php which generates a lot of my structure. Then for every page I do: include('top.php'); ....page stuff... include('footer.php'); in this case if I want to add a simple thing in my menu I only change it in top.php. For the language part I inlcude a lang.php which is like this: $lang["menuHome"]["en"]="Home"; $lang["menuHome"]["gr"]="Αρχική"; and so on. In my pages I only put print $lang["menuHome"][$l] where $l is "en" or "gr" (http://.../page.php?l=en) The site I must develop must be in php for the web but the customer asked to have it on a CD-ROM, which of course should be simple html. Is there a tool to convert my site in simple html?
