Subject: Built-in function: between
From: php@ikgcom.de (Alex Baumann)

Hi!
Since I'm using this function in each project I'm working on, how about 
making it a built-in function?

function between ($text, $between, $and) {
     $start = strpos($text, $between)+strlen($between);
     if ($start === false) return "";
     $end = strpos($text, $and, $start);
     if ($end === false) return "";
     return substr($text, $start, $end-$start);
}

Basicly this function returns a substring given in a text $text between 
two strings, $between and $and, occuring in $text.

Here are some examples:
echo between("PHP is awesome!", "PHP ", " awesome!");
 > is
echo between("PHP is awesome!", "P", "o");
 > HP is awes
echo between("PHP is awesome!", "PHP ", "great!");
 >

As mentioned above, this function is very useful, for example when 
parsing formated input data like html files, and everyone I told about 
it adopted it and is very thankful.

Thanks,
Alex
