How can debugging tools like var_dump and print_r be used effectively in PHP to troubleshoot issues with arrays and variables?

When troubleshooting PHP code that involves arrays and variables, using debugging tools like var_dump and print_r can be very helpful in understanding the structure and values of these data types. By using var_dump or print_r on an array or variable, you can easily see its contents and identify any issues such as incorrect values or unexpected data types. This can help you pinpoint the source of the problem and make the necessary corrections to fix it.

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

// Sample array with data
$fruits = array("apple", "banana", "cherry");

// Using var_dump to display the structure and values of the array
var_dump($fruits);

// Using print_r to display a human-readable representation of the array
print_r($fruits);
