#23894 [Ver]: sprinf format Problem

ID: 23894 User updated by: s dot masugata at digicom dot dnp dot co dot jp Reported By: s dot masugata at digicom dot dnp dot co dot jp Status: Verified Bug Type: Strings related Operating System: RedHat Linux6.2J PHP Version: 4.3.2 New Comment: Thank you very much for Reply. Since this function group is likely to be used quite extensively, the influence range seems to be large. A cause was not found although many things were investigated individually. I'm sorry that reporting is only always possible.

It happens also with "%02f" format. ------------------------------------------------------------------------ [2003-05-30 08:22:08] s dot masugata at digicom dot dnp dot co dot jp printf does not operate, either. <? $A = -1; printf( "%02d:", $A ); ?> reslt:[-1] 4.1.2 or 4.3.1: reslt:[-1:] ------------------------------------------------------------------------ [2003-05-30 05:12:17] s dot masugata at digicom dot dnp dot co dot jp Operation of sprintf is amusing. <? $A = -1; echo bin2hex( sprintf( "%02d:", $A ) ); phpinfo( ); ?> reslt:[2d31003a] NULL is added. It's satisfactory at 4.1.2 or 4.3.1. An environmental problem? ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=23894&edit=1
