I've tried the following method in the past:
<?php
set_time_limit(0);
$_SERVER['PATH_INFO'] = 'cron/controller/index';
$_SERVER['REQUEST_URI'] = 'cron/controller/index';
require_once('index.php');
?>
and putting this in a file in the codeigniter installation directory, calling it cron.php, and then invoking it via:
php /home/[username]/public_html/my_project/cron.php
If I type the URL to cron.php in my browser it works perfectly, however whenever its run via CRON I get a 404 error. Putting the following code in the show_404() function of CodeIgniter
function show_404($page = '')
{
print_r($_SERVER);
echo "\n\n";
die ($page);
}
results in getting the following output emailed to me:
Array
(
[SHELL] => /bin/sh
[MAILTO] => me@gmail.com
[USER] => [me]
[PATH] => /usr/bin:/bin
[PWD] => /home/[me]
[SHLVL] => 1
[HOME] => /home/[me]
[LOGNAME] => [me]
[_] => /usr/bin/php
[PHP_SELF] =>
[REQUEST_TIME] => 1266479641
[argv] => Array
(

)
[argc] => 1
[PATH_INFO] => cron/controller/index
[REQUEST_URI] => cron/controllers/index
)
home/[me]
Here I've [me] in place of my actual username.
Any ideas?
The simplest way to run a cron via CodeIgniter is to make a cron URL available via your app.
Then call it via wget
wget -O - -q -t 1 http://www.example.com/cron/run
Inside the controller you can then use a log to ensure the cron is not run too often i.e. if the Google robots trigger it by mistake.
A second method would be to use lynx
/usr/local/bin/lynx -source http://www.example.com/cron/run
You may also like to add --spider to ignore the response. This stops the request from timing out:
wget -O - -q -t 1 --spider http://www.example.com/cron/run
