Like julien already described... Previous Comments: ------------------------------------------------------------------------ [2015-03-31 12:04:23] julien at barmas dot name Hi, This is a normal case. You should use double quotes to use escaped character codes. '\0' is not equal to "\0". '\0' means the string antislash zero, "\0" means ASCII NULL or chr(0) Give a try to $i = trim($i, "\0"); or trim($i, chr(0)); Regards, ------------------------------------------------------------------------ [2015-03-31 11:46:53] nick dot sky dot pc at gmail dot com Description: ------------ $i = 11000; //$i = trim($i, 0); //or $i = trim($i, '\0'); //is the same echo $i; //11 //Is there is bug? I expect is '\0' work as slash and zero, but not just zero //PHP 5.4.32 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=69340&edit=1
