<?php
class foo {
var $myArray = Array();
function foo() {
foreach($this->myArray['value'] as $value){
}
var_dump($this->myArray);
}
}
$foo = new Foo();
produces the behaviuor you describe with PHP4
array(1) {
["value"]=>
NULL
}
PHP5 works as expected.
My suggestion for the reporter is to upgrade to PHP5 ASAP, you shouldnt
be using PHP4 nowdays anyway.

var $myArray = Array();
foreach($this -> mayArray['value'] as $value){
$myVAR += $value; //changed this line
}
actually it isn't asssigning to itself...
this version is correct.

Description:
------------
running a foreach loop on an empty array causes the test key to be
created.
Note this code has been pulled from a class, I have kept this structure
in case that has relevance.
Reproduce code:
---------------
var $myArray = Array();
foreach($this -> mayArray['value'] as $value){
$myArray += $value;
}
Expected result:
----------------
Ideally the loop wouldn't run, or would error when trying to locate a
none existant key.
Actual result:
--------------
myArray() has an empty key called "value" added to it.
