ID: 45472 Updated by: johannes@php.net Reported By: argreway at gmail dot com -Status: Open +Status: Bogus Bug Type: *General Issues Operating System: Linux RedHat 5 PHP Version: 5.2.6 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 The documentation says "(No version information available, might be only in CVS)" - it'S a PHP 6 feature. And no it'S not about binary numbers but binary strings (compared to unicode strings, which are a PHP 6 feature) Previous Comments: ------------------------------------------------------------------------ [2008-07-09 23:04:52] argreway at gmail dot com Description: ------------ The PHP documentation describes a function is_binary() at http://php.interec.es/manual/en/function.is-binary.php that does not exist. I have tried PHP 4 and 5 on different OS's and all return the same error message: PHP Fatal error: Call to undefined function is_binary() in /home/greway/test.php on line 2. I have downloaded the latest PHP 5.2.6 source and grep'ed for is_binary to find that there is not even a mention of this function in the source code. Am I the only one to every try and use this function? Or am I doin somthing wrong. Reproduce code: --------------- <?php if (is_binary(1001)) { echo "Yes"; } else { echo "No"; } ?> Expected result: ---------------- Print "Yes" Actual result: -------------- PHP Fatal error: Call to undefined function is_binary() in /home/greway/test.php on line 2 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=45472&edit=1
