How can a PHP debugger be utilized to identify and resolve issues in a script, as suggested in the forum thread?

To identify and resolve issues in a PHP script, a debugger can be utilized to step through the code, set breakpoints, inspect variables, and track the flow of execution. By using a debugger, developers can pinpoint the exact location of errors or unexpected behavior in their script, making it easier to troubleshoot and fix issues efficiently. 

// Example of using Xdebug with PHPStorm for debugging
// Step 1: Install Xdebug extension for PHP
// Step 2: Configure PHPStorm to listen for debug connections
// Step 3: Set breakpoints in the code where you suspect issues
// Step 4: Run the script in debug mode and step through the code to identify and resolve issues

// Example code snippet with a breakpoint set
function divide($numerator, $denominator) {
    $result = $numerator / $denominator;
    return $result;
}

$dividend = 10;
$divisor = 0;

// Set a breakpoint on the next line
$result = divide($dividend, $divisor);

echo $result;
