    Everything was ok before a small update (apache+php), but now I get this strange problem with php as shell script.

    this is my test.php (safe_mode is off and already tried with custom php.ini)
    #!/usr/local/bin/php -n
    echo shell_exec("uptime");

    An other strange thing:

    I get this error when I run that script as shell:
    # /root/bin/test.php

    But it is running normal when I execute with php command:
    # php -f ./root/bin/test.php -c /root/bin/php.ini
