 New Comment:

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

numeric indexes are stored as integers, comparing integer 0 with a
string not starting with a digit gives true as the string is casted to
an integer.

Expected, documented, behavior. Won't change.

Description:
------------
Array index value judgments must use absolute equal?

Test script:
---------------
$arr = array();
$arr['0'] = 'zero';
$arr['keyword'] = 'keyword';
foreach($arr as $key => $val) {
    if ($key == 'keyword') {
    //if ($key === 'keyword') { //ok
        echo $val."\n";
    }
}
//output:zero keyword
