Edit report at http://bugs.php.net/bug.php?id=51294&edit=1 ID: 51294 Updated by: pierrick@php.net Reported by: jnelson11 at gmail dot com Summary: 09 is no longer a valid value for chr() function -Status: Open +Status: Bogus Type: Bug Package: Strings related Operating System: centos 5.3 PHP Version: 5.3.2 New Comment: Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php When a number is preceded by a 0 it mean that you're using an octal notation. So when you wrote 09 it was converted to 0 since 9 is not a valid octal. If you want to print "\t" you can use chr(011) 011 = 9 http://php.net/manual/en/language.types.integer.php Previous Comments: ------------------------------------------------------------------------ [2010-03-14 04:55:24] jnelson11 at gmail dot com Description: ------------ you can no longer pass 09 int ascii value to chr() function to get a "\t" return value. I was previously running version 5.2.6 of php on my server a upgraded to version 5.3.2 A few of my providers send ascii with preceeding zero. Please let me know if 09 is no longer supported as a value that can be passed to chr(). Test script: --------------- // 5.3.2 returns 0 // 5.2.6 return "\t" ord(chr(09)); // 5.3.2 returns "\t" // 5.2.6 return "\t" ord(chr(9)); Expected result: ---------------- expected result is that both 09 and 9 should return "\t" Actual result: -------------- actual result is 09 returns null ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=51294&edit=1
