What are some best practices for effectively using a debugger in PHP development?

When using a debugger in PHP development, it is important to set breakpoints strategically at key points in your code where you suspect issues may be occurring. Additionally, utilize the debugger's features such as stepping through code, inspecting variables, and evaluating expressions to pinpoint the root cause of bugs. Finally, make use of logging and debugging tools provided by PHP frameworks or IDEs to enhance your debugging process.

// Example code snippet demonstrating the use of breakpoints and variable inspection with a debugger

function divide($numerator, $denominator) {
    // Set a breakpoint here to inspect variables
    $result = $numerator / $denominator;
    
    return $result;
}

$numerator = 10;
$denominator = 0;

// Call the function with problematic input
$result = divide($numerator, $denominator);

echo $result;
