How to ignore errors in shell_exec?

Question

I get shell command output in PHP as

$str = shell_exec("command");

and run the PHP script in the terminal. When it shell commandreturns an error, it will be printed on the terminal. How can I say shell_execto return command output only without error output?

Answer 1

You just need to discard the error output by redirecting stderrto/dev/null

$str = shell_exec("command 2>/dev/null");

Exit without errors - stdout- will be saved in $str, as before.
