What debugging techniques or tools can be used to identify and resolve issues with array structures in PHP?

When debugging array structures in PHP, one useful technique is to use the var_dump() function to display the contents of the array and its structure. This can help identify any unexpected values or inconsistencies within the array. Another helpful tool is the print_r() function, which can provide a more human-readable output of the array. Additionally, using foreach loops to iterate through the array elements and inspect their values can also aid in identifying and resolving issues. 

// Example code snippet demonstrating the use of var_dump() and print_r() to debug array structures

$array = array('apple', 'banana', 'cherry');
var_dump($array); // Display the structure and contents of the array

echo "<br>";

print_r($array); // Display a more readable output of the array

echo "<br>";

foreach ($array as $key => $value) {
    echo "Key: " . $key . ", Value: " . $value . "<br>"; // Iterate through the array elements and display key-value pairs
}
