What are the benefits of using print_r and var_dump functions for debugging PHP code?

When debugging PHP code, using print_r and var_dump functions can be incredibly helpful in understanding the structure and values of variables at different points in the code execution. These functions allow developers to easily inspect arrays, objects, and other complex data types, helping to identify issues such as incorrect data manipulation or unexpected variable values. By using print_r and var_dump, developers can quickly pinpoint the root cause of bugs and streamline the debugging process. 

// Example code snippet demonstrating the use of print_r and var_dump for debugging

// Create an array with some data
$data = array(
    'name' => 'John Doe',
    'age' => 30,
    'email' => 'john.doe@example.com'
);

// Debugging with print_r
echo "Using print_r: ";
print_r($data);
echo "<br>";

// Debugging with var_dump
echo "Using var_dump: ";
var_dump($data);
