title: How do I control script execution time in PHP
body: <p>for example I do have 5 PHP functions on a page which execute when loading. each functions has its own processing time and some of them take more time sometimes to complete the task. hence the total loading time of the said page is slow.</p>
  
  <p>my question is how do I control execution time for each script and set time limit for the same. I am aware that there is an in built function in PHP called <code>set_time_limit();</code> but it gives fatal error if time is beyond the maximum limit...</p>
