A quick question.

Is it possible to declare the callback function inline, in php? For example,

array_filter($input_array, "function($item) { $item['state'] != 0 }")

Yes, after php 5.3, you could use anonymous function.

array_filter($input_array, function($item) { return $item['state'] != 0; });

@jose Then you could use create_function http://php.net/manual/en/function.create-function.php – xdazz Oct 11 '12 at 11:13
Thank you for sharing your knowledge! – jose Oct 11 '12 at 13:53
Note that each line of code inside the anonymous function needs to end with a semicolon. – Tim Biegeleisen Jun 24 '19 at 14:08

array_filter($input_array, function($item) { 
    return $item['state'] != 0;
});

This functionality is available from 5.3 or > version of php. In 5.4> version will support $this in inline Anonymous Functions

with create_function? ex:

 $result = array_filter($array, create_function('$a','return preg_match("#\S#", $a);'));
