How to Pass Variables to Command-Line PHP Scripts?

Passing Variables to Command-Line PHP Scripts

When running a PHP script from the command line using crontab, you may encounter challenges in passing variables. The syntax you attempted with a query string (myfile.php?type=daily) is not supported in this context.

To resolve this issue, pass the variable as an argument to the PHP executable. Replace your command with:

php myfile.php daily

Within your PHP script, retrieve the variable from the $argv array:

$type = $argv[1]; // Assuming '$argv[0]' contains the script name

Alternative Approaches:

If the script is also used as a webpage, you have two options:

1. Utilize a shell script with Wget to pass the variable:

#!/bin/sh
wget http://location.to/myfile.php?type=daily

2. Check whether the script is called from the command line or not within the PHP script:

if (defined('STDIN')) {
  $type = $argv[1];
} else {
  $type = $_GET['type'];
}

Remember to ensure that the $argv array contains the necessary variables and handle edge cases as needed.
