Sorry, but your problem does not imply a bug in PHP itself. For a list of more appropriate places to ask for help using PHP, please visit http://www.php.net/support.php as this bug system is not the appropriate forum for asking support questions. Due to the volume of reports we can not explain in detail here why your report is not a bug. The support channels will be able to provide an explanation for you. Thank you for your interest in PHP. This is completely expected. First of all, '' === "", seriously, there is 0 difference between those two. Next, I think you misunderstood the manual. It just says you CAN use an empty string, and it WILL work. If an empty string is already defined as a key, it will simply overwrite it. $test = array('zero' => '1', '' => '2', "" => '3' ); echo $test['zero']."\n<br />"; //outputs: 1 echo $test['']."\n<br />"; //outputs: 3 echo $test[""]."\n<br />"; //outputs: 3 '' = empty string "" = exact same empty string you could even use a heredoc to make such an empty string. They are all exactly the same. Read up on single and double quotes to find out how they differ.
