 New Comment:

or, add a third argument to callback, which is the "regex self" or the regex 
index?

Description:
------------
In PHP 5.5 'e' key preg_replace is deprecated: 
https://wiki.php.net/rfc/remove_preg_replace_eval_modifier

But I don't know how to replace evaled preg_replace with preg_replace_callback 
in 
some case.

For example:
$repl = [
            '/(\d{2}|(?<!\d))([pm])(\d{2}|)([PMc])/e' => '$this->_op("$3", 
"$4", 
rtrim($this->_op("$1", "$2"), ";"))',

            '/(\d{2}|)([MPmplrc])/e' => '$this->_op("$1", "$2")',
        ];

$str = preg_replace(array_keys($repl), array_values($repl), $str);

Test script:
---------------
$repl = [
            '/(\d{2}|(?<!\d))([pm])(\d{2}|)([PMc])/e' => function($m) { return 
$this->_op($m[3], $m[4], rtrim($this->_op($m[1], $m[2]), ";"))'; },

            '/(\d{2}|)([MPmplrc])/e' => function ($m) { return 
$this->_op($m[1], $m[2]); },
        ];

$str = preg_replace(array_keys($repl), array_values($repl), $str);

Expected result:
----------------
It works.

Actual result:
--------------
Warning: preg_replace_callback(): Requires argument 2, 'Array', to be a valid 
callback in my.php on line 359
