CHECK URL
How it can be checked that a URL exists or not in PHP.There is one way is to use fopen function then passing the URL as a parameter. Like this, <? $URL = "http://www.abc.com"; $fp = @fopen ($URL, "r"); if (!$fp) { die ("Cannot open website $URL!"); } ?> But I think that there should have some other smart technique.
Can I Check SSL Somehow With PHP?
Ever since I got a server for our site, it just opens new issues. Here is the problem: My SSL Cert somehow got corrupted. The server is managed, so they fixed it right away once I noticed it, but nobody was able to checkout until it was fixed, and I cannot check the site every hour. Here is what I want to do (but the server people say it is not possible): Is there a way, by chron or otherwise, to run a PHP that requests a secure page, and if it does not respond, it emails a warning? It seems that this should be able to be done without too much trouble. Any ideas?

How To Check If I've Been CHMODED 220 ?
My host and I have come to a dissagreament on filedownload sizes, and everyday when I wake up, I see that I'm back to 220 for that /files/ directory. I'd like to point out that it's nothing illegal, it's just gamepatches, and yes... these can get quite big. Now, untill I settle that, I need to redirect my visitors IF that site is innaccessible to another box... how can i detect if the user gets a 403 page so that I can redirect him? Had a look at "socket_read()" etc... but can't make heads or tail in it yet, will keep looking in there, but if someone can give me a push in the right direction, I'd apreciate it.

How To Check If Theres Something In STDIN
How do i check if there is something new in STDIN? I ran into this problem when i was doing some simple command line script that takes input from STDIN.

How To Check Value Of Variable??
I have this input box that is optional called "Reason" If a user submits this form with data in the "Reason" form then I want to take those contents and add to them, ie: if (isset($reason)) { $reason_message = "Reason for rejection: $reason";} else { $reason_message = "";} Then I have $reason_message sent alow with other stuff in an email.

Bottom line: is there a way for me to tell that "Reason" has no value and there for not send "Reason for rejection:"

Check For Cookies
This is more of a pain than I thought it would be. I need a simple code segment to determine whether a browser accepts cookies or not. When I pass variables between pages when cookies are turned off, the global variables are empty between pages, fine, that tells me cookies store the global variables - right? I store the values in $_session and when cookies are turned on values are passed between web pages - I can see these values in fields that are displayed in the next web page. I need to be able to check on the 'first' entry webpage after a user enters that page directly whether or not their browser accepts cookies at that point. Everything I have tried complex to simiple won't work. How do I do this?
Check My Math!
Not sure about you, but when I run this, it tells me 59001.31 doesn't equal 59001.31. Change each side of the equation by a hundreth or two and it checks. Change it a bit more, and it won't. _What_ is going on here?! <?php $subtotal=59001.31; $principal=58605.33; $interest=395.98; $check=$principal+$interest; echo("<pre>"); echo("Check: " . $check . " "); echo("Subtotal: " . $subtotal . " "); if($check!=$subtotal) { echo("Check (" . $check . ") does not equal subtotal (" . $subtotal . ")"); // Check doesn't equal subtotal } else { echo("Check (" . $check . ") equals subtotal (" . $subtotal . ")"); // Check does equal subtotal } echo("</pre>"); ?>

Check Wildcard URL
I'm looking for a function that will help me determine whether or not a URL entered by a user matches specific requirements. This is done using $_POST. Basically the format of the URL must be either: www.example.com, *.example.com, www.example.*, or *.example.* - or some kind of combination such as www.url.com*. I don't want to allow a star in the 'url'. So in theory, to check this, all i would have to do is make sure the string contains: [www and/or *].[text].[text and/or *]
Postcode Check
I have no idea where to start with the code, but would like in a way that i could input true and false values, eg if it contained "sw19" or "SW19" value = true.

Check File
I'm trying to find a way to search a text file for a certain key, and there will be one key on each line. I'm hoping it could return 0 if there's no match, and 1 if there is. I'm familiar with this in other languages, but I can't find how in PHP you can read a certain line of a file. I can get most of the code already: $var=0; for($i=1;$i<=file_lines();$i+=1) { if (file_read_line()=="key") { $var=1;}} But I'm sure you spot two probmlems, they are file_lines() and file_read_line(). Does anybody know the proper replacements, or a simpler way?
Check File Age.
I am tring to make a script that i will turn into a cron job. Idealily it would check the age of the file and then figure out if it is more then 48 hours old and if it is it will delete it. i have figured out how to check the age and how to delete the files, but how would i find out if they are 48 hours old?
Check What Page Someone Came From?
I need to find out how to see what page someone came from. I need this because I need to check if they came from a downloads.php page in order to download a file. This will stop hot linking. How it works right now is you click a link on the downloads.php page, that sends the file id to a page called files.php. The files.php figures out which file url to get from the database. Before figures out which file url to get, I need it to see if the link on downloads.php was clicked.
Mysql Check.
<?php $sql = "SELECT * FROM songs WHERE Title = '".$_POST['songtitledelete']."' LIMIT 1"; mysql_query($sql) or die ("Couldn't execute $sql: " . mysql_error()); if (mysql_query($sql) == NULL){ echo "No such song"; } else { $sql2 = "DELETE FROM songs WHERE Title = '".$_POST['songtitledelete']."' LIMIT 1"; mysql_query($sql2) or die ("Couldn't execute $sql: " . mysql_error()); } ?> That should make sense? I want to check if the song is there. Otherwise it always says "Song Deleted". I want something to detect whether it's there before deleting the row. When i run it now i dont see "No such song" when i enter an invalid song name.

Check CHMOD Value?
I'm building a script that builds itself. It's working fine, but I was struck with a thought; for some of the files that will be script-created, they will need to be 777 CHMOD value. So is there a code that checks a file's CHMOD value? I basically want to say 'if $file has 777 CHMOD do this, else do this'. I can do the if bit, I was just wondering how I would do the CHMOD bit?
Email Check

My form is submitting even with the same email address being used. Any ideas?
