regular expressions

Recommended Posts

I created a script using regular expressions to pull info from text files. The script works fine on my test server , but when I upload it to my web host the regex strings do not work the same. Looking at the php info I see that my test server is php 5.04 built --with-pcre-regex=/usr' and the server api is apache 2 handler. Now on the web host it is php 5.05 built --with-mbregex and the server api is CGI. They are both Linux. Test server is apache 2.0.54 / web host is apache 1.3.36. Is there a difference in the way mbregex handles regex vs. pcre? Or maybe it is cgi. Not really sure what is going on, but any help would be greatly appreciated, thanks....

$regx = "Name: [-0-9a-zA-Z''_ ]{4,}";

On my test server this to grab ( Name: 'name' name name ) appostrophes included

But on the live server it will only match one of the apostrophes and stop where the second one is

first off, i have to ask why you have two apostrophes in your regex anyway. when you're doing a character grouping like that, you only need it once. the second thing that catches my eye is that you have no delimiters on your regex... that seems a little odd to me. is there a reason for it? now, to approach the actual regex issue: are you wanting to only grab the first name (the one within the single quotes)? if so, i think this [b]should[/b] work:
[code]
$String = "Name: 'name' name name";
preg_match('|Name: [-0-9a-z\'_]{4,}|i', $String, $match);
echo $match[0];
[/code]
