codeigniter-cli-bootstrap

Formerly: Cron Bootstrapper

A simple bootstrap file that you can use to directly run your CodeIgniter controllers from the command line and redirect the output to a log file.

Features

  • Easy to use
  • No core framework hacking
  • Bootstrap file exists independently of your application
  • Supports runtime limit
  • Log the results of each run
  • Run directly without the PHP command (on UNIX systems only)

Installation

  1. Copy the code at the bottom of this code and save it in a file called cron.php somewhere outside the document root.

  2. Set the CRON_CI_INDEX constant to the full absolute file/path of your CodeIgniter index.php file

  3. Make this file directly executable:

chmod a+x cron.php

Usage

You can use this file to call any controller function:

./cron.php --run=/controller/method [--show-output] [--log-file=logfile] [--time-limit=N] [--server=http_server_name]

Options

--run=/controller/method

(Required) The controller and method you want to run.

--show-output

(Optional) Display CodeIgniter's output on the console (default: don't display)

--log-file=logfile

(Optional) Log the date/time this was run, along with CodeIgniter's output

--time-limit=N

(Optional) Stop running after N seconds (default=0, no time limit)

--server=http_server_name

(Optional) Set the $_SERVER['SERVER_NAME'] system variable (useful if your application needs to know what the server name is)

Troubleshooting

Invalid interpreter: /usr/bin/php^M error when running cron.php:

This is caused by not having UNIX-style line breaks, which usually happens by copying files created on other operating systems. Use this command to convert the line breaks to UNIX format:

mv cron.php cron.old
tr -d '\15\32' < cron.old > cron.php
rm cron.old

Fatal error in cron.php around line 111:

require(CRON_CI_INDEX); // Main CI index.php file

Check that you have correctly defined the path to your application's main index.php defined correctly:

define('CRON_CI_INDEX', '/var/www/vhosts/htdocs/index.php'); // Your CodeIgniter main index.php file

No errors or output and the script doesn't seem to run:

Make sure PHP error logging is turned on that your PHP error log is writable.

Code that depends on sessions may cause this. Use some conditional logic to see if the CRON constant is defined before auto-loading any authentication libraries.
