Are PHP scripts run using the "php" command affected by the timeout limit? I plan to schedule php scripts using cron.

The default timeout is 30 seconds. It can be changed using the max_execution_time php.
By default, the maximum execution time for PHP scripts is set to 30 seconds. If a script runs for longer than 30 seconds, PHP stops the script and reports an error. You can control the amount of time PHP allows scripts to run by changing the max_execution_time directive in your php. ini file.
The set_time_limit() function lets you set how long a script should be allowed to execute. This value is usually set inside php. ini under the max_execution_time setting; however, you can override that here. The function takes one parameter, which is the number of seconds you want the script to have.
To increase the script execution time, you can use the following snippet at the top of your script. ini_set ( 'max_execution_time' , '300' ); In the above example, it would set the max_execution_time directive to 300 seconds.
Yes, but you can set an unlimited timeout by adding this to the top of your script:
set_time_limit(0);
Some systems, such as Ubuntu, actually already start with separate CLI and Apache configurations in /etc/php5.
The relevant command in the ini file is:
max_execution_time = 30 ; Maximum execution time of each script, in seconds
However, if you are unable to modify the php.ini for whatever reason, you can create a new php.ini with configuration settings favourable to the command-line, and point to the file like so:
php -c /path/to/ini/php.ini -f script.php
Or, you can use Cailin's solution, and set the time limit at the top of the file - but if you are running on a server with PHP 'safe mode' enabled, then you will have to use your own ini file.

Depends. If your php binary is the PHP CLI interface, the default max_execution_time is zero (meaning there is no limit).
On the other hand, if it's the older-style CGI binary, you will be affected by the max_execution_time limit, and you'll need to call set_time_limit to get rid of it (assuming you're not in the dreaded PHP safe mode).
