How can debugging techniques be used effectively to identify and resolve errors in PHP scripts?

To effectively identify and resolve errors in PHP scripts, debugging techniques such as using print statements, utilizing error reporting, and stepping through the code with a debugger can be helpful. By strategically placing print statements to output variable values or checking for specific conditions, you can pinpoint where the issue lies. Enabling error reporting will also provide detailed information about any errors that occur during script execution. Lastly, using a debugger tool can help you step through the code line by line to understand the flow of execution and identify any logic errors. 

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

// Using print statements to debug
$variable = 10;
echo "Value of variable: " . $variable;

// Debugger tool (e.g., Xdebug) can be used to step through the code
