PHP - Preg_match Help
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. Thanks in advance kev.

Thanks. 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 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" 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.... )

When I use the following code to check for posted characters it allows the insertion of ( ) brackets to be posted. if(!preg_match('/^([-_ a-z0-9]){2,50}$/i', $_POST['title'])) { echo "<script>alert('Please enter a Title 2-50 alphanumeric characters,\\nspaces, hyphens and underscores also accepted!)</script>"; } It should on allow 2-50 alphanumeric characters and spaces, hyphens and underscores! What am I missing? I have this $val="my friend is a female"; how to check whether a word "male" is there or not using preg_match() i wish to get FALSE result for that case and TRUE if i modify a bit into $val="both male/female" thanks in advance! Hi, I need a preg_match for the following criteria: - no leading or trailing white space allowed - only alphanumeric characters and spaces are allowed (no full stops, commas apostrophe's, explanation marks, quotes, etc) - only one space allowed between each word (if there is more than one word) Thanks. |
