ID: 6992 Updated by: waldschrott Reported By: david@php.net Status: Analyzed Bug Type: Documentation problem Assigned To: Comments: hehe, you´ve been fooled by auto-conversion... :) <?php echo "CONERTMETOZERO"==0; ?> See? Perhaps we need some chapter about auto-conversion? Telling which rules apply comparing 'AZ' against 'A' or 'AAT' or 0 or whatever Previous Comments: --------------------------------------------------------------------------- [2000-10-03 08:01:12] david@php.net The text string "NULL" compares equal to 0. This is rubbish. The string is not empty. NULL may compare equal to 0. The string containing NULL should not. [david@serena php4]$ ./php <? if ("NULL" == 0) echo "This is not good."; ?> X-Powered-By: PHP/4.0.3RC1 Content-type: text/html This is not good. ./configure --with-config-file-path=pwd --------------------------------------------------------------------------- Full Bug description available at: http://bugs.php.net/?id=6992
