A function I made to find the first occurrence of a particular needle not enclosed in quotes(single
or double). Works for simple nesting (no backslashed nesting allowed).
<?php
function strposq($haystack, $needle, $offset = 0){
$len = strlen($haystack);
$charlen = strlen($needle);
$flag1 = false;
$flag2 = false;
for($i = $offset; $i < $len; $i++){
if(substr($haystack, $i, 1) == "'"){
$flag1 = !$flag1 && !$flag2 ? true : false;
}
if(substr($haystack, $i, 1) == '"'){
$flag2 = !$flag1 && !$flag2 ? true : false;
}
if(substr($haystack, $i, $charlen) == $needle && !$flag1 && !$flag2){
return $i;
}
}
return false;
}
echo strposq("he'llo'character;\"'som\"e;crap", ";");
//16
?>
