What are some common debugging techniques for PHP code?

One common debugging technique for PHP code is to use the var_dump() function to display the contents of variables and arrays at different points in your code to help identify any issues. Another technique is to use error_reporting() function to set the level of error reporting and display any errors or warnings that may occur during the execution of your script. Additionally, using a debugger tool like Xdebug can help step through your code line by line and track variable values to pinpoint any bugs.

// Using var_dump() to display the contents of a variable
$variable = "Hello, World!";
var_dump($variable);

// Setting error reporting level to display all errors and warnings
error_reporting(E_ALL);

// Using Xdebug to step through code and track variable values
// Install Xdebug extension and configure your IDE for debugging
