Here's a stab: <function>array_filter</function> iterates over each value in the <parameter>input</paramter> array passing them to the <parameter>callback</parameter> function. If the <parameter> callback</parameter> function returns true, the current value from <parameter>input</paramter> is returned into the result array. Array keys are preserved. Regards, Philip
