# 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](https://docs.digitalocean.com/products/app-platform/reference/buildpacks/php/index.html.md). 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](https://www.php.net/manual/en/configuration.file.per-user.php) to the root of your app with the following contents:

`.user.ini`

```text
max_execution_time=your_preferred_execution_time
```

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