How can debugging techniques like printing array elements help in identifying issues with PHP code execution?

One common issue in PHP code execution is incorrect array manipulation, which can lead to unexpected results or errors. By printing array elements at different stages of the code, developers can track the values and identify where the issue occurs. This debugging technique helps in pinpointing the root cause of the problem and allows for targeted fixes. 

// Example code snippet demonstrating debugging technique by printing array elements
$array = [1, 2, 3, 4, 5];
$sum = 0;

// Print array elements before calculation
print_r($array);

// Calculate sum of array elements
foreach ($array as $value) {
    $sum += $value;
}

// Print sum after calculation
echo "Sum of array elements: " . $sum;
