filter_array(3)

NAME
filter_array() - return a selective sub-array

SYNOPSIS
mixed *filter_array( mixed *arr, string fun, object ob, mixed extra );

DESCRIPTION
filter_array() returns an array holding the items of <arr> which passed sucessfully through the function <fun> found in object <ob>. The function <fun> is called for each element in <arr> with that element as parameter. The second parameter <extra> is sent in each call if given. An object is considered to have passed sucessfully through <fun> (and hence is included in the return array) if <fun> returns 1. If <arr> is not an array, then 0 will be returned.
