For a list of more appropriate places to ask for help using PHP, please visit http://www.php.net/support.php as this bug system is not the appropriate forum for asking support questions. Due to the volume of reports we can not explain in detail here why your report is not a bug. The support channels will be able to provide an explanation for you. Thank you for your interest in PHP. ------------------------------------------------------------------------ [2014-08-04 07:48:37] datibbaw@php.net This happens because after 'Z' comes 'AA', and 'AA' is smaller than 'Z'. The correct condition in this case is: $char != 'AA' The other way (recommended): foreach (range('A', 'Z') as $char) { } ------------------------------------------------------------------------ [2014-08-04 07:36:25] yppah56 at yahoo dot com dot tw Description: ------------ 0000 When for() judge 'Z', find error. for ($char='A'; $char<='Z'; $char++) echo $char; Echo not as expected. Maybe counting error. Test script: --------------- // this program is OK for ($char='A'; $char<='Y'; $char++) { echo $char; } // this program is Error for ($char='A'; $char<='Z'; $char++) { echo $char; } ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=67754&edit=1
