PHP - Problems With Preg_match
Hi
I am using preg_match to look through some data (collected from external source which works fine) and display it. I have the preg_match to work fine using: Code: [Select] <?php $rhys = '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">.......(external website data which works fine)'; preg_match('/<td width="60%" class="dataRegularUlOff">Price<\/td> <td width="40%" class="dataRegularUlOff">([^<]+)</', $work, $matchesarray); print_r($matchesarray[1]); ?> However as the string $rhys wont be present in the actual test.php file that contains the preg_match it doesnt seem to work. I have the data going to a file called dump.txt which works fine, and I can send that info to the test.php page and echo that, however if I save the data to a variable like: Code: [Select] <?php $work = file_get_contents("dump.txt");preg_match('/<td width="60%" class="dataRegularUlOff">Price<\/td> <td width="40%" class="dataRegularUlOff">([^<]+)</', $work, $matchesarray); print_r($matchesarray[1]); ?> It doesnt seem to do anything, and the page appears blank. I have tried variations of using fread to try and get it to work, but no luck. Does any one have any idea why it isnt working? Thanks Rhys Similar TutorialsHi... I have a string (called $textData) with the following format: Code: [Select] 1. e4 {[%emt 0:00:10]} c5 {[%emt 0:00:04]} 2. c3 {[%emt 0:02:15]}etc I need to replace the square brackets/special chars within that string with " "... so my first thought was to use preg_match to find the matches.. then preg_replace/str_replace to update them. To find the patterns, I think this is correct: preg_match('/\{([^\}]*)\}/', $textData, $matches); echo print_r($matches, true); // returns Array ( [0] => {[%emt 0:00:10]} [1] => [%emt 0:00:10] ) // returns nothing else I expected the preg_match to search through the whole of $textData. Then I could replace the square brackets/special chars with a spaces. Thank you for your time!! I need to select an array item based on my preg result. for example: Code: [Select] $content = 'test-1'; $match = preg_replace('|test-([0-9])|', $array['\\1'], $content); is this possible? Why dosent this work, im trying to match upper case, lower case and numbers only Code: [Select] $id = '3xDJ7@#'; if (!preg_match('/^[a-zA-Z0-9]/', $id)){ echo "ERROR!"; }else{ echo 'ok'; } This always echos "ok" i'm trying to grab the file name from mediafire to my database caption, I have rapidshare working fine. here's the code for rapidshare Code: [Select] if($type==1) { $words=$links[$j]; preg_match("/rapidshare\.com\/files\/\d+\/(.+)/",$words,$match); unset($words); $words=$match[1]; unset($match); $words=preg_split("/[_\.\-]/",$words); $lastword=array_pop($words); if($lastword=="html") array_pop($words); $words=implode(" ",$words); $words=preg_replace("/\s{2,}/"," ",$words); $caption=mysql_real_escape_string($words); unset($words); }How ever, i'm not sure which preg_match would be the correct one for mediafire.. appreciate any help. information.txt <li><img src="http://www.lol.com" alt="0" /></li> <li><img src="http://www.lol.com" alt="1" /></li> <li><img src="http://www.lol.com" alt="4" /></li> <li><img src="http://www.lol.com" alt="9" /></li> <li><img src="http://www.lol.com" alt="1" /></li> <li><img src="http://www.lol.com" alt="7" /></li> <li><img src="http://www.lol.com" alt="2" /></li> How can I get the alt="$ValueIwant" for each with a preg_match How to a check if a php variable value is one of the following characters: A to J, or ,k to t, (ie.: A B C D E F G H I J k l m n o p q r s t)
I tried:
if (preg_match[A-Jk-t], $checkChar)
{
// do this
}
Hi,
I have a "scraped" string and want to use the preg_match() to give me just a pice of it.
The string is from a webpage, but is dynamic....
here´s the typical string format:
<a class="stripped-link lightblue-link profile-page-link" href="/x/xxx+xxx+xxx/xxxx">HER IS THE WANTED TEXT</a>
The orange is static. The green (the xxxx is the dynamic part of the string)
Can I use the preg_match() for this?
thanks (and yes I´m a newbe.... )
Hi guys, I have been using this code: preg_match('/<h2>(.*?)<\/h2>/', $data, $matches); which i changed to: $tag1 = 'h2'; $tag2 = 'h2'; preg_match('/$tag1(.*?)$tag2/', $data, $matches); however i need it to work allowing variables (of any character or symbol) within $tag1. I tried $tag1 = 'h(.*?)2'; $tag2 = 'h2'; preg_match('/$tag1(.*?)$tag2/', $data, $matches); but that does not work .... essentiall the whole thing would work like this (example only): firstpartoftag1VARIABLE1lastpartoftag1VARIABLE2tag2 ps the preg_match should only capture the VARIABLE2 data not VARIABLE1 any ideas or help would be much appreciated cheers in advance im trying to make a script so i can get users details like longitude, latitude etc

I have a DOMDocument which I inspect an HTML page for links (href) That part works however I am not sure how to use preg_match if I only want to display a link in this layout: <tr> <td headers="c1"><a title="Link to entity information." tabindex="1" href="CORPSEARCH.ENTITY_INFORMATION?p_nameid=3236937&p_corpid=3227476&p_entity_name=%41%72%77%65%6E%20%45%71%75%69%74%69%65%73&p_name_type=%41&p_search_type=%42%45%47%49%4E%53&p_srch_results_page=0">ABC LLC</a></td> </tr> I hope someone is really good at preg_match to help me. Thanks. I'm pretty new to this, How exactly could i get the text between the www. and .com? so if i have a url: http://www.facebook.com I want to just return "facebook" I know $regex_pattern is wrong but I need a solution to find a content between <body> and </body>. Code: [Select] <?php $content = "<html><head><title>Your IP</title></head><body>Your IP Address: 63.1.142.154</body></html>"; $regex_pattern = "/<body>(.*)<\/body>/"; $preg_match($regex_pattern,htmlspecialchars($content),$matches); print_r( $matches ); ?> in my site search some of the results come out still with html. i have used the strip tags function but how would i use the preg_match function to get rid of the "> still left over? I've tried alot of different ways, google, but just can't find the correct way to do this.. I'm trying to search for a word in an inputted string.. here's the code <html> <head><title>TESTING</title></head> <body> <form method="GET" action="<?php echo $_SERVER['PHP_SELF']; ?>"/> email: <input type=text name=email value="" /><br/> feedback: <input type=text name=ex value=""/><br/> <input type="submit" value="submit" /><br/> </body> </html> <?php $email = $_GET['email']; $ex = $_GET['ex']; $pattern = '/^[a-zA-Z0-9\-\.]+@[a-zA-Z0-9\-]+\.[a-zA-Z]+$/'; //$pattern1 = '/nprezident/prezident/'; if(!preg_match($pattern, $email)){ echo 'invalid email address<br/>'; } else { echo 'good to go<br/>'; } if(preg_match('/nprezident/,/prezident/', $ex)){ echo 'just something about that sentence is nice'; } else { echo 'no good'; } ?> Ok the one I'm having a problem with is the second preg_match when trying to search for two words i can get one word to print but when i use add a second word it gives an error. How do i add a second word? Hi,

Hi im trying to do a registration form and i am new to using preg_match. I keep getting the error "( ! ) Warning: preg_match() [function.preg-match]: No ending delimiter '^' found in C:\wamp\www\registration1.php on line 67" and for every other line I use preg_match. this is an example of how i have used it Code: [Select] if ( preg_match('^[[:alnum:]\.\'\-]{4,50}$', stripslashes(trim($_POST['UserName']))) ) { $UserName = mysql_real_escape_string($_POST['UserName']); $query = "SELECT UserName FROM Users WHERE UserName = '$UserName'"; $result = @mysql_query($query); $num = @mysql_num_rows($result); im such a noob at this can someone please help me I would also like to add that I have read the http://www.php.net/manual/en/function.preg-match.php page but i dont really understand it. Im trying to match this string, but i dont wat to match normal words like "hello world 646" Code: [Select] $string = "2ab055843241f20044af82ae0d5ace04"; //always over 15 chars - without spaces if ( preg_match('~^[0-9\s]+$~D', $string)) { echo 'yes'; } If i can do it with preg_match that would be great Hi, I have the following code which FTPs to a site, gets the source code for a HTML file and then puts the data inbetween <TITLE> and </TITLE> into an array and this works fine: <?php $file = file_get_contents("ftp://user:pass@domain/public_html/index.html", "r"); if (!$file) { echo "<p>Unable to open remote file.\n"; exit; } preg_match_all ('/<TITLE>(.*)<\/TITLE>/msU', $file, $matches, PREG_SET_ORDER); print_r ($matches); ?> Rather than finding a match for data between <TITLE> and </TITLE> however I would like it to pull back what is inbetween the following: <!--START--> and <!--END--> I have tried the following but it doesn't put anything into the array: preg_match_all ('/<!--START-->(.*)<\/!--END-->/msU', $file, $matches, PREG_SET_ORDER); This is the content of the html file if this helps: Code: [Select] <TITLE>The Title</TITLE> <!--START--><p><strong>Some Text</strong></p> <p><strong><img src="images/IMAG0152_2.jpg" alt="" width="200" height="100" /></strong></p> <!--END--> i can get a match on stuff between TITLEs but not START and END.. I'm not sure how to change preg_match_all to work!! i've tried loads of combinations but can't get any to work, but i'm not really sure on modifiers and patterns or escaping etc, if anyone could help that would be great.
