What steps can be taken to ensure that PHP scripts are written in a way that minimizes the occurrence of undefined variable errors?

To minimize the occurrence of undefined variable errors in PHP scripts, it is important to initialize variables before using them and to check if they are set before accessing their values. Additionally, using error reporting functions like `isset()` or `empty()` can help prevent these errors from occurring. 

// Initialize variables to avoid undefined variable errors
$variable1 = '';
$variable2 = 0;

// Check if variables are set before using them
if(isset($variable1) && isset($variable2)){
    // Your code here
}
