What is the purpose of debugging in PHP programming?

Debugging in PHP programming is essential for identifying and fixing errors in the code. It helps developers trace and eliminate bugs, ensuring that the program runs smoothly and as intended. By using debugging tools and techniques, developers can pinpoint the root cause of issues, such as syntax errors, logical errors, or runtime errors, and make the necessary corrections to improve the code's functionality.

// Example code snippet demonstrating debugging in PHP
$number1 = 10;
$number2 = 0;

// Attempting to divide by zero to trigger a runtime error
$result = $number1 / $number2;

// Using var_dump() to display the error message and line number
var_dump(error_get_last());
