What are the different methods for debugging and troubleshooting PHP code when dealing with arrays?

When debugging and troubleshooting PHP code with arrays, one common issue is incorrectly accessing or manipulating array elements. To solve this, you can use var_dump() or print_r() functions to inspect the array structure and values at different stages of your code execution. Additionally, utilizing foreach loops to iterate through arrays can help identify any unexpected values or keys. 

// Example code snippet demonstrating the use of var_dump() and foreach loop for debugging arrays

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

// Debugging array using var_dump()
var_dump($fruits);

// Iterating through array using foreach loop
foreach ($fruits as $index => $fruit) {
    echo "Index: $index, Value: $fruit\n";
}
