New Comment:
I suspected this as a possible source for the wrong result and already
tried it out.
Here is the modified code again:
<?php
$array1[0] = array("a" => 3, "b" => 3);
$array1[1] = array("a" => 9, "b" => 3);
$array1[2] = array("a" => 11, "b" => 11);
$array1[3] = array("a" => 11, "b" => 11);
$array1[4] = array("a" => 15, "b" => 11);
$array1[5] = array("a" => 2, "b" => 2);
$array_backup = $array1;
foreach ($array1 as $key => $val) {
if ($val["a"] == $val["b"]) {
$array2[] = array_splice($array_backup,$key,1);
}
}
echo "array_backup:<br>";
echo "<pre>";
var_dump($array_backup);
echo "</pre>";
echo "<br>array2:<br>";
echo "<pre>";
var_dump($array2);
echo "</pre>";
?>
To be sure I even loaded $array_backup manually to exclude the unlikely
case of referencing the variable instead of copying.
In my special case the curious behaviour of the function is not that
important. I find another way to solve the problem. But I thought it is
a good idea to inform you and your developing team.
I think it is a bug.

The problem is you're modifying the array while you're walking through
it with foreach. That causes the mess. Don't know what to do with this,
though.

Oh oh, I'm very sorry. I should be more accurated when writing a
message :-)
Here is the code again (by copy & paste):
<?php
$array1[0] = array("a" => 3, "b" => 3);
$array1[1] = array("a" => 9, "b" => 3);
$array1[2] = array("a" => 11, "b" => 11);
$array1[3] = array("a" => 11, "b" => 11);
$array1[4] = array("a" => 15, "b" => 11);
$array1[5] = array("a" => 2, "b" => 2);
foreach ($array1 as $key => $val) {
if ($val["a"] == $val["b"]) {
$array2[] = array_splice($array1,$key,1);
}
}
echo "array1:<br>";
echo "<pre>";
var_dump($array1);
echo "</pre>";
echo "<br>array2:<br>";
echo "<pre>";
var_dump($array2);
echo "</pre>";
?>
Please, try it out. You'll get a weird result...

That 1 is not what I meant, I was talking about => instead of =.
You are using
foreach ($array1 as $key = $val) {
and it should be
foreach ($array1 as $key => $val) {
Does it work now?

No, that wasn't the reason. I only misspelled the foreach-loop
when I wrote the bug report (forgot the '1').

Your foreach-loop is wrong. It should be
foreach ($array1 as $key => $val) {
Does it work now?
