Send errors to stderr instead of stdout

Hi,


Is there a way to send PHP/CI4.5 generated errors to stderr instead of stdout ?

For eg, I have a crontab which sends an email only when it detects content on stderr : 

PHP Code:

*/10 * * * * root php myscript.php > /dev/null 


Here are some examples to illustrate the different scenarii:

PHP Code:

    public function test()
    {
        CLI::write("hello");
    } 


=> No mail sent => OK because written to stdout



    public function test()

PHP Code:

    {
        CLI::error("An error");
    }    


=> mail sent => OK because written to stderr

    public function test()

PHP Code:

    {
        $t = 1 / 0;
    } 


=> no mail sent => Not ok because it generates a DivisionByZeroError to stdout instead of stderr

Thanks for your help,

Fred
