How can debugging techniques be used to troubleshoot issues with filling arrays in PHP loops?

When troubleshooting issues with filling arrays in PHP loops, it is important to use debugging techniques such as printing out the values being added to the array at each iteration to identify any errors or unexpected behavior. This can help pinpoint where the issue is occurring and allow for corrections to be made accordingly. 

// Example code snippet demonstrating debugging techniques for filling arrays in PHP loops

$array = []; // Initialize an empty array

for ($i = 0; $i < 5; $i++) {
    $value = $i * 2; // Calculate the value to be added to the array
    $array[] = $value; // Add the value to the array
    
    // Debugging output to check the value being added at each iteration
    echo "Added value: $value <br>";
}

// Output the final array to verify the values have been correctly added
print_r($array);
