How can proper debugging techniques be applied to identify and resolve issues in PHP scripts?

Issue: To identify and resolve issues in PHP scripts, proper debugging techniques such as using var_dump(), print_r(), and error_reporting() can be applied. These functions help to display the values of variables, arrays, and error messages, respectively, which can aid in pinpointing the source of the problem and fixing it.

// Example code snippet demonstrating the use of var_dump() to debug an array
$array = [1, 2, 3];
var_dump($array);
