How can debugging techniques be applied to identify discrepancies in data when working with arrays in PHP?

When working with arrays in PHP, debugging techniques can be applied to identify discrepancies in data by using functions like var_dump() or print_r() to display the contents of an array and check for any unexpected values or missing elements. Additionally, using loops to iterate through the array and print out each element can help pinpoint where the issue lies. By carefully examining the output of these debugging techniques, you can quickly identify and resolve any discrepancies in the data. 

// Sample array with discrepancies
$data = array('apple', 'banana', 'cherry', 'date');

// Display the contents of the array for debugging
var_dump($data);

// Loop through the array to print out each element
foreach ($data as $key => $value) {
    echo "Element $key: $value <br>";
}
