Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to
report
a bug at http://bugs.php.net/how-to-report.php

Use === here (since "test"==0 by design).

Description:
------------
When i use foreach to go through an array, and use an if statement to
evaluate the $key, it enters into the if statement incorrectly when
$key = 0, even though the if statement reads 'if ($key == "test")'

It is not supposed to enter when $key = 0, but as the Actual result
shows, it does. 

This does not happen even when $key = 1, tho. 
I have tested this on both PHP 4.3.4 and PHP 4.0.1

Thank you very much, keep up the good work.

Reproduce code:
---------------
<?
$the_array["aap"] = array("figure"=> "circle",
"colour"=>"blue");
$the_array[] = array("figure" => "triangle",
"colour"=>"red");
$the_array["test"] = array ("figure" => "sqaure",
"colour"=>"neon");

foreach ( $the_array as $key => $value){
	if ($key == "test") {
		echo "\$key = $key\n";
		echo "A ". $value["colour"]. " " .
$value["figure"]."\n";
	}
}
?>

Expected result:
----------------
The following output in text:
$key = test
A neon sqaure

Actual result:
--------------
The following output in text:
$key = 0
A red triangle
$key = test
A neon sqaure
