Function to find the first occurence of any object of the array.
<?php
function findfirstof( $txt, $arr, $start )
{
$pos = -1;
foreach( $arr as $v )
{
$p = strpos( $txt, $v, $start );
if ($p===FALSE)
continue;
if (($p<$pos)||($pos==-1))
$pos = $p;
}
return $pos;
}
?>
Ex:
$str = "find, the first word...";
$firstW = findfirstof( $str, ",?.:!" ); //returns "find"
