# CloudLinux: Making global PHP changes for the native PHP version

If you’re running **CloudLinux** and find that the default PHP limits (such as memory or upload size) are insufficient, there are a few ways to address this.

For individual accounts, limits can be adjusted by placing a custom **php.ini file** inside the account’s **public_html directory** (and the **wp-admin directory** if WordPress is in use).

However, if you need to apply a **server-wide default** for the **native PHP version**, this can be done by modifying the global PHP configuration used outside of CloudLinux PHP Selector.

> [!WARNING]
> This method applies **only to the system (native) PHP binary**.
> 
> It does **not** affect PHP versions managed via **CloudLinux PHP Selector**, which are each configured separately.

## Modifying the global php.ini file

1. Edit the system **php.ini** file, located in **/usr/local/lib**
2. Modify the following common settings according to your requirements:
  - `max_execution_time = 300`
  - `memory_limit = 128M`
  - `upload_max_filesize = 128M`
  - `post_max_size = 128M`

Ensure `post_max_size` is equal to or greater than `upload_max_filesize`⁣. Otherwise, file uploads may fail.

1. Once the changes have been saved, rebuild the CageFS environment to ensure they are applied consistently for all users:

```bash
cagefsctl --force-update
```

The updated PHP limits will now apply **server-wide** to the native PHP version, including within CageFS.

For environments using **PHP Selector**, PHP limits should instead be adjusted via one of the following utilities:

- CloudLinux **PHP Selector**
- cPanel’s **MultiPHP INI Editor**
