Note Submitter: gareth dot williams at antaisx dot com ---- If you want the list items in the string to be array keys (rather than values assigned to numeric keys), consider using strtok instead: function explodetokeys($sDelim, $sInput) { $aResult=Array(); $sArrayKey=strtok($sInput, $sDelim); while ($sArrayKey !== false) { $aResult[$sArrayKey]=1; $sArrayKey=strtok($sDelim); } } explodetokeys(' ', 'one two three'); will return: Array('one'=>1, 'two'=>1, 'three'=>1) This is useful if you need to search for the existence of a string in the string many times, as searching an ordered array using isset($array[$string]) in a loop should be much faster than using strpos many times in a loop. If you know of a better way of doing this, please reply!
