Execute a PHP file

php [-f] xxx.php

Can pass parameters

php [-f] xxx.php 'hello' 'world' 2015

The parameters passed to the script can be obtained in the global variable $ argv. The global variable $ argc stores the number of member variables in the $ argv array (instead of the number of parameters passed to the script program).





001.php






Execute 001.php

php 001.php 'hello world' 2015

output

php -r 'echo Hello World
;'

#output Hello World

You can also run PHP code directly



php -r 'echo Hello World;' #Hello World
