How can better error handling and debugging techniques be implemented in PHP scripts to address issues like the one described in the forum thread?

Issue: The forum thread describes a problem with undefined variables causing errors in PHP scripts. To address this issue, better error handling and debugging techniques can be implemented by using functions like isset() to check if a variable is set before using it, and by enabling error reporting to display warnings and notices for undefined variables. 

// Enable error reporting
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Check if variable is set before using it
if(isset($variable)){
   // Code that uses $variable
} else {
   // Handle the case when $variable is not set
}
