What steps can PHP developers take to ensure that deprecated or outdated functions are not inadvertently used in their codebase?

To ensure that deprecated or outdated functions are not inadvertently used in a PHP codebase, developers can utilize the PHP `error_reporting` function to display warnings for deprecated functions. By setting the `error_reporting` level to `E_ALL & ~E_DEPRECATED`, developers can receive notifications about any deprecated functions being used in their code. 

// Set error reporting to display warnings for deprecated functions
error_reporting(E_ALL & ~E_DEPRECATED);

// Your PHP code goes here
