My PHP app is timing out and throwing 5xx errors

Running out of time to execute a request is the most common cause of timeouts and 5xx errors in PHP apps on App Platform. By default, App Platform allows your app 30 seconds to execute a request before timing out. You can increase this time by editing your app’s .user.ini file and setting the max_execution_time value to a higher number. user.ini files allow you to configure and override PHP settings on a per directory basis.

To increase your app’s maximum execution time, add a .user.ini file to the root of your app with the following contents:

    
        
            
max_execution_time=your_preferred_execution_time

        
    

You can set the execution time to a maximum of 100 seconds.
