New Comment:
Accepting an array of callbacks can lead to unreconcilable ambiguities. For
example:
class A {
function __toString() { ... }
function __invoke($a) { ... }
function foo($a) { ... }
}
function foo($a) { ... }
$a = new A;
preg_replace_callback([..., ...], [$a, 'foo'], $subject);
There are three different ways of interpreting the callback argument, all
equally valid:
1. `(string)$a` and `foo(...)`
2. `$a(...)` and `foo(...)`
3. `$a->foo(...)`

I think it would be better if prey_replace_callback function will accept array
of
callbacks as a 2nd argument.

Oops⦠sorry. My mistake. Test script is:
$repl = [
'/(\d{2}|(?<!\d))([pm])(\d{2}|)([PMc])/e' => function($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]); },
];
$str = preg_replace_callback(array_keys($repl), array_values($repl), $str);

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