Awesome! Thanks.

Hello masters of the regex. I would like your help. I need an expression that would extract the version out of this string. Everything between the last "-" and ".". INPUT: database_name-10182011946-v1.0.2.sql OUTPUT: v1.0.2 Any ideas?

I guess I should update that one.

Try this: if (ereg('[^A-Za-z0-9]', $text)) { echo "This contains characters other than letters and numbers"; } else { echo "This contains only letters and numbers"; }

I think I got it. Adding the ENT_NOQUOTES seemed to do the trick. It was encoding the quotes and messing it up. $string=htmlentities($string,ENT_NOQUOTES); Thanks for all your help. I appreciate it.

I figured out the issue. I applied htmlentities. $string=htmlentities($string); Any way around this? I don't want any other html code displayed.

$string = '<a href="http://yahoo.com">Yahoo</a>'; $pattern = '/((?:https?):\/\/[-A-Z0-9+&@#\/%?=~_|$!:,.;]*[A-Z0-9+&@#\/%=~_|$])/i'; if(preg_match_all($pattern, $string, $match)) { $string=$match[0][0]; echo $string; } Output http://yahoo.com">Yahoo</a>

Oops... /((?:https?):\/\/[-A-Z0-9+&@#\/%?=~_|$!:,.;]*[A-Z0-9+&@#\/%=~_|$])/i

$pattern = '/((?:https):\/\/[-A-Z0-9+&@#\/%?=~_|$!:,.;]*[A-Z0-9+&@#\/%=~_|$])/i'; if(preg_match_all($pattern, $string, $match)) { $string=$match[0][0]; echo $string; } Input: http://yahoo.com this is some text Output http://yahoo.com The above is ok Input <a href="http://yahoo.com">Yahoo</a> Output http://yahoo.com" I want to remove that last quote.

I suppose I should rephrase this. I want it to stop at the first space, the SECOND quote, or the SECOND apostrophe, and begin at http:// or https://

$pattern = '/((?:https?|ftp):\/\/[-A-Z0-9+&@#\/%?=~_|$!:,.;]*[A-Z0-9+&@#\/%=~_|$])/i'; if(preg_match_all($pattern, $string, $match)) { $string=$match[0][0]; echo $string; } I came up with that using preg_match_all. It's almost what I want. $string = "<a href="http://google.com">Google</a> this is some text http://yahoo.com this is some texthttp://msn.com"; If the string was what I have above, how do I make the pattern stop at a " or '. Otherwise the first string produced would be http://google.com">Google</a>. I just want it to be http://google.com. It only stops at the first space. I would like it to stop at the first space, the first ", or the first '. So I would want the output of $string=$match[0][0] to be http://google.com. The output of $string=$match[0][1] to be http://yahoo.com, and so on.

One more question. Is there a way to choose which match in the string it gets? match[1] = The first url in string match[2] = The second url in string

Thanks Zach

I've searched. I couldn't find anything. Thats not what my question was related to. I tried that. Doesn't work.
