String Chopping Functions

These are some string functions I wrote one night.

<?
## find everything before
function FindAllBefore($str, $delimit) {
        if(strpos($str, $delimit) === false) { return false; }
        else {
           $pos1 = 0;
           $pos2 = strpos($str, $delimit);
           return substr($str, $pos1, $pos2);
  }     
}
## find everything before, including
function FindAllBeforeIncluding($str, $delimit) {
        if(strpos($str, $delimit) === false) { return false; }
        else {
           $pos1 = 0;
           $pos2 = strpos($str, $delimit)+strlen($delimit);
           return substr($str, $pos1, $pos2);
  }     
}
## find everything after
function FindAllAfter($str, $delimit) {
        if(strpos($str, $delimit) === false) { return false; }
        else {
           $pos1 = strpos($str, $delimit)+strlen($delimit);
           $pos2 = strlen($str);
           return substr($str, $pos1, $pos2);
  }     
}
## find everything after, including
function FindAllAfterIncluding($str, $delimit) {
        if(strpos($str, $delimit) === false) { return false; }
        else {
           $pos1 = strpos($str, $delimit);
           $pos2 = strlen($str);
           return substr($str, $pos1, $pos2);
  }     
}

## find inside, including
function FindInsideIncluding($str, $start, $end) {
        if(strpos($str, $start) === false) { return false; }
        else if (strpos($str, $end) === false) { return false; }
        else {
           $pos1 = strpos($str, $start);
           $pos2 = strpos(FindAllAfter($str, $start), $end)+strlen($end)+strlen($start);
           return substr($str, $pos1, $pos2);
  }     
}


## find inside
function FindInside($str, $start, $end) {
        if(strpos($str, $start) === false) { return false; }
        else if (strpos($str, $end) === false) { return false; }
        else {
           $pos1 = strpos($str, $start)+strlen($start);
           $pos2 = strpos(FindAllAfter($str, $start), $end);
           return substr($str, $pos1, $pos2);
  }     
}
?>
