Question

array_intersect takes two arrays and looks for matching === values and returns the result. However the values in the array have to match character for character. Is there a function or a method for comparing two arrays and looking for values that contain similar strings instead of equal similar strings. Something like stripos but with array_intersect.

$array1 = array("howdyhorse", "monkeyjoe", "bill", "donkeymonkey", "carrothorse")
$array2 = array("bill", "horse", "monkeybunk", "apple", "panda")

function($array1, $array2);

Returns an array = array("bill", "horse", "monkeyjoe")

The order is of no particular concern.

Answer 1

Is running all the values of each array through something like

foreach( $array as $slice )
    $slice = trim( preg_replace( $pattern, $replacement ) ) ;

to make everything lowercase and remove spaces and special chars and then doing an array_intersect an option?
