PHP 4.0 Bug #8163 Updated: The string "0" tests true as empty()

ID: 8163 Updated by: hholzgra Reported By: juhl@eisenstein.dk Status: Bogus Bug Type: Scripting Engine problem Assigned To: Comments: see also http://php.net/version4/incompatibilities.php [...] The String "0" is now considered empty [...] Previous Comments: --------------------------------------------------------------------------- [2000-12-08 05:31:59] zak@php.net empty() is used to test if a variable is set and contains a non-empty, non-zero value. The behaviour you describe is expected and desired. --------------------------------------------------------------------------- [2000-12-08 05:24:52] juhl@eisenstein.dk The script below produce the following oputput: a is of type string b is of type string b is empty I believe the 'b is empty' part is wrong, as the variable actually contains a string that is one char long and as such is not empty. <?php $a = '1'; $b = '0'; echo 'a is of type '.gettype($a).'<br>'; echo 'b is of type '.gettype($b).'<br>'; if (empty($a)) { echo 'a is empty<br>'; } if (empty($b)) { echo 'b is empty<br>'; } ?> Best regards, Jesper Juhl --------------------------------------------------------------------------- Full Bug description available at: http://bugs.php.net/?id=8163
