Removing text before and after keyphrase

[stubarny1]

Hello everyone,

 

I'm looking to turn this string:

 

$string = "jhdfgsdf984w5yisrek903_START_OF_WEBPAGE_http://www.google.com_END_OF_WEBPAGE"

 

into this string:

 

$string = "http://www.google.com"

 

before the phrase "_START_OF_WEBPAGE_" could be any types of symbol or character.

 

I've been trying to use regular expressions but can't seem to get them to work.

 

Many thanks for your help.

if (preg_match('/_START_OF_WEBPAGE_(.+)_END_OF_WEBPAGE/', $string, $matches)) {
$string = $matches[1];
} else {
$string = "";
}

 

Yeah?

$string = preg_replace('~/_START_OF_WEBPAGE_(.+?)_END_OF_WEBPAGE~','$1',$string);
