PHP - parse a string between two strings
This is a handy little function to strip out a string between two specified pieces of text. This could be used to parse XML text, bbCode, or any other delimited code/text for that matter.
function get_string_between($string, $start, $end){
$string = " ".$string;
$ini = strpos($string,$start);
if ($ini == 0) return "";
$ini += strlen($start);
$len = strpos($string,$end,$ini) - $ini;
return substr($string,$ini,$len);
}
$string = " ".$string;
$ini = strpos($string,$start);
if ($ini == 0) return "";
$ini += strlen($start);
$len = strpos($string,$end,$ini) - $ini;
return substr($string,$ini,$len);
}
$fullstring = "this is my [tag]dog[/tag]";
$parsed = get_string_between($fullstring, "[tag]", "[/tag]");
echo $parsed; // (result = dog)

This is a nice little function that I'm using to parse data from emails.

Glad it helped. You can always consider the $2 donation as mentioned above

Great script…though, what if the string contains multiple instances of the same tag…a bold for example?

It will just parse the first instance. In which case, just add a third, optional parameter to indicate the starting character search position (int)

Hi-I was wondering how it would be made to parse this string> "dog+cat+mouse+fish"
so that the result would be
"dogcatmousefish"
Thanks in advance.

I think you'd have to use eregi for that

str_replace("+","","dog+cat+mouse+fish") = "dogcatmousefish"
