Setting PHP.INI path (or file) for PHP CLI shell scripts

Running a PHP script from the command-line, or CLI, is quite useful at times and is often used to perform some automated task, like a CRON cleanup script, to send out reminders, etc.

It’s common that these CLI scripts need some, but possibly not all, settings that are similar to the main application’s. I may, for example want to include the database configuration settings shared with the main application. So I often create a separate php.ini file for this purpose.

Running /usr/bin/php -c /my/very/special/path cronScript.php is simple enough, but what if I want to be able to create an “executable” PHP shell script? The obvious answer would be something like:

#!/usr/bin/php -c /my/very/special/path

at the top of the .php file, followed by my PHP code, right? Except that may not do what you want. I could not get the PHP interpreter to load anything in /my/very/special/path by using the above construct, even if it works from the actual command-line. After banging my head against the wall for a while, this turns out to work for these “shell scripts”:

#!/usr/bin/php -c=/my/very/special/path

Note the use of the = (equal) sign between the -c and the path (or file).

Carry on.
