Description
array
preg_grep ( string pattern, array input)
preg_grep() returns the array consisting of
the elements of the input array that match
the given pattern.
Since PHP 4.0.4, the results returned by preg_grep()
are indexed using the keys from the input array. If this behavior is
undesirable, use array_values() on the array returned by
preg_grep() to reindex the values.
P°φklad 1. preg_grep() example // return all array elements
// containing floating point numbers
$fl_array = preg_grep ("/^(\d+)?\.\d+$/", $array); |
