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 strings are understood as numeric values. This is not exactly an int cast. i.e. "01a" == "001a" is not true, as the operands are not numeric. however (int)"01a" == (int)"001a" == 1 Previous Comments: ------------------------------------------------------------------------ [2008-01-14 13:33:25] technique at ircf dot fr Description: ------------ I have noticed that the equal operator will systematically try to cast expressions as integers, even when it is useless. This may cause problems like this (see the code below). Wouldn't be better to cast only one operand ONLY if the two operands are not of the same type ? For example : "1" == 1 , would cast the right operand (1) as a string and then compare it with the first "123" == "456", would not cast any operand because they already have the same type I know that this issue can be solved using the identity operator (===) but I find weird that "001" == "0001" returns true, or am I missing something ? Reproduce code: --------------- <?php if ("0001" == "000001"){ echo "Impossible !!!"; } ?> Expected result: ---------------- Nothing Actual result: -------------- Impossible !!! ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=43839&edit=1
