Find needle in haystack, where needle is array of needles

Question

I have a function that takes a string (the haystack) and an array of strings (the needles) and returns true if at least one needle is a substring of the haystack. It didn't take much time or effort to write it, but I'm wondering if there's a PHP function that already does this.

function strstr_array_needle($haystack, $arrayNeedles){
    foreach($arrayNeedles as $needle){
        if(strstr($haystack, $needle)) return true;
    }
    return false;    
}

Answer 1

just a suggestion...

function array_strpos($haystack, $needles)
{
    foreach($needles as $needle)
        if(strpos($haystack, $needle) !== false) return true;
    return false;
}

Answer 2

I think the closest function would be array_walk_recursive(), but that requires a callback. So using it would probably be more complicated than what you already have.
