The cli sapi module has the following three methods to obtain the PHP code you want to run:


1.


Run the specified file in PHP.


Php my_script.php


Php-f my_script.php


The above two methods (using or without the-f parameter) can run the given my_script.php file. You can select any file to run the script. the PHP script you specified does not have to use. php as the extension. they can have any file name and extension.

2.


Run the PHP code directly on the command line.


Php-r 'print _ r (get_defined_constants ());'


When using this method, pay attention to the substitution of shell variables and the use of quotation marks.


Note: read the preceding example carefully. there is no start or end mark when running the code! After the-r parameter is added, these tokens are not required, and adding them will lead to syntax errors.


3.


Provide the PHP code to be run through standard input (stdin.


The above usage provides us with very powerful functions, so that we can dynamically generate PHP code and run the code through the command line as follows:


$ Some_application | some_filter | php | sort-u> final_output.txt


The preceding three methods for running code cannot be used at the same time.
