Send errors to stderr instead of stdout - Fred9176 - 08-14-2024

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

I found this may help but not sure.

Email all cron stdout+stderr output only on stderr

Create your custom Exception Handler.

Thanks for your help.

I finally found another wrapper script which fits my needs :
