what the meaning of #!/usr/bin/php -q

Question

I look at some php script in centos,I notice there is #!/usr/bin/php -q

What is the meaning of this option? because I cannot see it in php --help

Answer 1

The manpage for php(1) describes this option, and it is also documented in the PHP Manual; Command line options:

Option	Long Option	Description
-q	--no-header	Quiet-mode. Suppress HTTP header output (CGI only).

Answer 2

The line itself is known as a "shebang" or, more formally, an Interpreter Directive.
It tells the shell which interpreter (and options) to use to process [the rest of] the script.
