       string escapeshellarg (string  $arg)

DESCRIPTION

       escapeshellarg(3)  adds	single quotes around a string and quotes/escapes any existing single quotes allowing you to pass a string directly

       shell functions coming from user input. The shell functions include exec(3), system(3) and the backtick operator.

	On Windows, escapeshellarg(3) instead removes percent signs, replaces double quotes with spaces and adds double quotes around the string.
