Description:
------------
if you disable functions using the php.ini variable
disable_functions and you seperate the functions using commas when you get a warning for attempting to use those functions it incorrectly displays multiple function names.

I have disable_functions set as:
disable_functions = system, exec, passthru, proc_open, shell_exec, popen

If i create a test script:
<?
system("ls");
exec("ls");
?>

I get the following output:
Warning: system, exec, passthru, proc_open, shell_exec, popen() has been disabled for security reasons in /pathtoscript/test.php on line 2

Warning: exec, passthru, proc_open, shell_exec, popen() has been disabled for security reasons in /pathtoscript/test.php on line 3

The expected output should just show the single function name which you are trying to use.

Expected result:
----------------
Warning: system() has been disabled for security reasons in /pathtoscript/test.php on line 2

Warning: exec() has been disabled for security reasons in /pathtoscript/test.php on line 3

Actual result:
--------------
Warning: system, exec, passthru, proc_open, shell_exec, popen() has been disabled for security reasons in /pathtoscript/test.php on line 2

Warning: exec, passthru, proc_open, shell_exec, popen() has been disabled for security reasons in /pathtoscript/test.php on line 3
