Multiple includes in PHP script called via command line - php

Question

I'm working on creating some scheduled tasks that perform system maintenance on my database (i.e. inactive user cleanup, data archiving, etc.) and also generate/email automated data reporting.
Currently I have it setup so that each task is its own file and there is a master file that calls the appropriate tasks.
For example:
run_daily.php
<?php
define('INCLUDE_CHECK',true);
require $_SERVER['DOCUMENT_ROOT'].'/db/connect.db.php';
require $_SERVER['DOCUMENT_ROOT'].'/includes/definitions.inc.php';
$get_dailyTasks = mysql_query("SELECT task_name FROM task_scheduler WHERE task_type='task' AND task_occurs='daily' AND task_active=1");
while(($dailyTasks = mysql_fetch_assoc($get_dailyTasks)))
{
include $schedule.'tasks/'$dailyTasks['task_name'].$tsk;
};
$get_dailyReports = mysql_query("SELECT task_name FROM task_scheduler WHERE task_type='report' AND task_occurs='daily' AND task_active=1");
while(($dailyReports = mysql_fetch_assoc($get_dailyReports)))
{
include $schedule.'reports/'.$dailyReports['task_name'].$rbf;
};
?>
user_cleanup.php
<?php
$disable_inactive = "UPDATE users SET enabled='no' WHERE (created < (CURDATE() - INTERVAL 3 MONTH) AND last_active IS NULL AND enabled='yes') OR (last_active < (CURDATE() - INTERVAL 3 MONTH) AND enabled='yes')";
mysql_query($disable_inactive);
?>
I'm attempting to set it up this way because I plan on having the master file run via command line and scheduled as a task scheduler job on the server. I will have access to modify the files as needed but I will not easily be able to change what is scheduled to run once it is setup. My thought was to schedule a master task and this would allow me to add/remove sub-tasks as needed.
The problem I'm running into though is that when I test everything via command line, the sub-task never seems to return control to the main task. After the first sub-task runs (regardless of how I order them) none of the other sub-tasks after it run.
