What are the best practices for handling variables in PHP scripts to avoid errors like the one mentioned in the forum thread?

The issue mentioned in the forum thread likely stems from not properly initializing variables before using them in PHP scripts. To avoid errors, it's essential to always initialize variables before using them to prevent undefined variable errors. One way to do this is by setting default values for variables or checking if they are set before using them in the script. 

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

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