[PHP-DEV] inconsistent return value from array_map() when used with call_user_func_array()

[Jochem Maas]

Hi devs,

I was playing around with call_user_func_array() and array_map() on
PHP 5.0.2 (cli) (built: Nov  9 2004 19:00:36) and noticed the that
calling call_user_func_array() on 'array_map' with more than 2 args
(i.e. more than just the name of the callback and array
argument that are required for 'array_map') then a numerically indexed array
is returned, where as with just the minimum 2 args the associative keys of array
are maintained:

question is have I missed something, am I doing something wrong or it this
a 'buglet'? (I haven't been able to find anything in the bugs DB regarding this)

[I originally posted this on generally but got no response.]

===========================================================================

function array_map_assoc($callback, $arr)
{
    $args = func_get_args();
    return call_user_func_array("array_map", $args);
}

$sq = chr(39);

// start array
$arr1 = array(    "name" => "\"{$sq}Testing{$sq}\"",
        "email" => "\"Yadda{$sq}s \"YADDa\"<script language={$sq}Testing{$sq} 
source={$sq}{$sq}></script>\"");

$arr2 = array_map_assoc("strip_tags", $arr1);
$arr3 = array_map_assoc("htmlentities", $arr2, array( ENT_QUOTES, ENT_QUOTES ));
$arr4 = array_map_assoc("htmlentities", $arr2);
$arr5 = array_map_assoc("strip_tags", $arr1, array( "<p>", "<p>" ));
// test without array_map_assoc
$arr6 = call_user_func_array("array_map", array("strip_tags", $arr1, array( "<p>", 
"<p>" )));

echo "-----\n\n";
var_dump($arr1, $arr2, $arr3, $arr4, $arr5, $arr6);

===========================================================================

OUTPUTS (on my machine):
-----
array(2) {
  ["name"]=>
  string(11) ""'Testing'""
  ["email"]=>
  string(63) ""Yadda's "YADDa"<script language='Testing' source=''></script>""
}
array(2) {
  ["name"]=>
  string(11) ""'Testing'""
  ["email"]=>
  string(17) ""Yadda's "YADDa"""
}
array(2) {
  [0]=>
  string(31) "&quot;&#039;Testing&#039;&quot;"
  [1]=>
  string(42) "&quot;Yadda&#039;s &quot;YADDa&quot;&quot;"
}
array(2) {
  ["name"]=>
  string(21) "&quot;'Testing'&quot;"
  ["email"]=>
  string(37) "&quot;Yadda's &quot;YADDa&quot;&quot;"
}
array(2) {
  [0]=>
  string(11) ""'Testing'""
  [1]=>
  string(17) ""Yadda's "YADDa"""
}
array(2) {
  [0]=>
  string(11) ""'Testing'""
  [1]=>
  string(17) ""Yadda's "YADDa"""
}
