Bug description: preg_replace() misbehavior with multidimensional arrays as "subject"
paramenter
Description:
------------
<?php
/*
preg_replace() misbehavior.
Treats Multidimensinal arrays in "subject" in a really weird way.
*/
class object {};
$alpha = new object;
$alpha->beta = "alpha-beta";
$alpha->gama->x = "hola";
$array = array("a" => "abc", "azw", array("a", "b", array("af")),
$alpha->beta, $alpha->gama );
print_r (preg_replace("/[a|e|i|o|u]/", "#", $array));
/*
and this is what i get:
Array
(
[a] => #bc
[0] => #zw
[1] => Arr#y
[2] => #lph#-b#t#
[3] => Obj#ct
)
Is is correct that i get an array element called "Arr#y" and Obj#ct??
shouldn't preg_replace go through the arrays recursively?
The manual is not very clear about that:
"If subject is an array, then the search and replace is performed on every
entry of subject , and the return value is an array as well."
anyways...
I don't think that if the function finds an array or an object, treats it
as string "Array" and string "Object",
*/
?>
Reproduce code:
---------------
<?php
class object {};
$alpha = new object;
$alpha->beta = "alpha-beta";
$alpha->gama->x = "hola";
$array = array("a" => "abc", "azw", array("a", "b", array("af")),
$alpha->beta, $alpha->gama );
print_r (preg_replace("/[a|e|i|o|u]/", "#", $array));
?>
Expected result:
----------------
Array
(
[a] => #bc
[0] => #zw
[1] => Array
(
[0] => #
[1] => b
[2] => Array
(
[0] => #f
)
)
[2] => #lph#-b#t#
[3] => stdClass Object
(
[x] => hol#
)
)
Actual result:
--------------
Array
(
[a] => #bc
[0] => #zw
[1] => Arr#y
[2] => #lph#-b#t#
[3] => Obj#ct
)
