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. ------------------------------------------------------------------------ [2003-05-30 08:28:58] s dot masugata at digicom dot dnp dot co dot jp Similarly, neither vsprintf nor vprintf also operates. <? $A = -1; $Array[0] = $A; echo bin2hex( vsprintf( "%02d:", $Array ) ); vprintf( "%02d:", $Array ); ?> reslt:[2d31003a] reslt:[-1] 4.1.2 or 4.3.1: reslt:[2d313a] reslt:[-1:] ------------------------------------------------------------------------ [2003-05-30 08:24:33] elmicha@php.net No, it doesn't look like an environmental problem. sprintf() and printf() indeed append an extra NUL character for negative numbers: % LC_ALL=C php -r ' printf( "%03d\n", -1 ); ' | xxd 0000000: 2d30 3100 0a -01.. 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
