Description:
------------
I think we need a better strpos that can find multiple positions (an array) quickly.
to avoid the use of functions like :

$str = "&foobar&foobaz";
$toFind = "foo";
$start = 0;
while( ($pos = strpos(($str),$toFind,$start) !== false)) {
        echo 'Found '.$toFind.' at position '.$pos."\n";
        $start = $pos+1; // start searching from next position.
}

//Output:
   // Found foo at position 1
   // Found foo at position 8


Expected result:
----------------
an array of all positions

Actual result:
--------------
a simple position
