[SOLVED] running php functions on command line

[abazoskib]

I know that I am capable of running php files on a CLI, however how can I run specific functions within a php file alone? And moreovr, how do I specify variable values when running a command such as 'php myFile.php'? thanks for the insight in advance.

Didn't unerstood your first question.

 

Maybe neither the second one... lol... but when you run php from CLI, you can get the count of parameters with the superglobal $_SERVER['argc'] - arguments count - and you can get all the parameters with the superglobal array $_SERVER['argv'] - arguments values.

 

Example:

 

script.php

<?php
print 'Total parameters = '. $_SERVER['argc'] . '\n';
print 'Script name = '. $_SERVER['argv'][0] . '\n';

for ($i = 1; $i < $_SERVER['argc']; $i++) {
    print 'Parameter '. $i . ' = '. $_SERVER['argv'][$i] . '\n';
}
?>

 

Then you can run like this:

 

php script.php first second

 

It will print:

 

Total parameters = 3
Script name = script.php
Parameter 1 = first
Parameter 2 = second

 

Note that the index 0 from $_SERVER['argv'] is ALWAYS the script name (it's also a parameter).
