Why is this true?

My guess:

You are comparing an integer with a string. PHP wants to do an integer compare. It therefore converts "text" to an integer, which is 0, and 0 == 0 evaluates to true.

Compare that with:

Code:

$key = 0;
if ((string) $key == "text") {
    echo "true";
} else {
    echo "false";
}
