This class was used to check if the PHP execution time limit was reached.

It can take note of the current time when a class object is created.

The class can also check later if the time that passed since the script was started was less than a given limit, as long as that limit value is lower that the time limit set in the max_execution_time option of php.ini PHP configuration file.

PHP provides a feature that is used to limit the time that a script can run.

This is useful for instance to prevent that bugs may cause excessive load on the server due to scripts that execute tasks that take too long to finish.

Sometimes it is better to split the tasks in multiple executions of the same PHP script to avoid that each execution exceeds the PHP execution time limit, which by default is 30 seconds.

This class can help determining when a script that runs a long task is close to exceed the PHP execution time limit.

This way, PHP applications can pause the execution of each task and redirect the Web page access that runs that long task, so the next request handled by the same PHP script can resume the execution of that long task where it was paused.

Time Limit Manager Component for PHP

This component helps you to validate if your script reaches the allowed maximum runtime.

Furthermore, you can set your own runtime limit (as long as it is below the limit in you php.ini).

The build status of the current master branch is tracked by Travis CI: build status Latest stable

The scrutinizer status are: code quality

The versioneye status is: dependencies

Downloads: Downloads this Month

It is also available at


  • provides easy setting of runtime limit
  • gives you the advantage to add a buffer before reaching the limit to easy up reacting when limit is reached
  • helps you to set the limit in seconds, minutes or hours (same for the buffer)
  • comes with DependentInterface and AwareInterface



By Hand

mkdir -p vendor/net_bazzline/php_component_time_limit_manager
cd vendor/net_bazzline/php_component_time_limit_manager
git clone

With Packagist

composer require net_bazzline/php_component_time_limit_manager:dev-master


$manager = new Net\Bazzline\Component\TimeLimitManager\TimeLimitManager();

while (!empty($dataSet)) {
    if ($manager->isLimitReached()) {
        //exit while loop, shutdown process
    } else {
        $data = array_shift($dataSet);
        //work on data set
