Valgrind also reports several errors in this code:
<?php
$ao = new ArrayObject( $_GET ) ;
unset( $ao['index']['i'] ) ;
?>

Well, sorry, I have put Actual Result and Expected result in the wrong
order.

Description:
------------
When a multidimentional superglobal is used to feed ArrayObjet, the
first unset of a sub-index is ignored.
- it is ok with a "normal" array, I've seen this only with $_REQUEST
and $_GET
- it is ok with $_GET as a simple array (one dimension)
- the second call to unset() succeed, either if is the exact same call
or if I try to unset another index, only the first fails
Reproduce code:
---------------
<?php
// call the script with ?index[i]=1&index[j]=2
$ao = new ArrayObject( $_GET ) ;
unset( $ao['index']['i'] ) ; // ignored
var_dump($ao) ;
unset( $ao['index']['j'] ) ; // ok
var_dump($ao) ;
unset( $ao['index']['i'] ) ; // ok
var_dump($ao) ;
Expected result:
----------------
object(ArrayObject)#1 (1) {
["index"]=> array(2) {
["i"]=> string(1) "1"
["j"]=> string(1) "2"
}
}
object(ArrayObject)#1 (1) {
["index"]=> array(1) {
["i"]=> string(1) "1"
}
}
object(ArrayObject)#1 (1) {
["index"]=> array(0) {
}
}
Actual result:
--------------
object(ArrayObject)#1 (1) {
["index"]=> array(1) {
["j"]=> string(1) "1"
}
}
object(ArrayObject)#1 (1) {
["index"]=> array(0) {
}
}
object(ArrayObject)#1 (1) {
["index"]=> array(0) {
}
}
