What are some debugging techniques for identifying array values in PHP?

When debugging PHP code that involves arrays, one technique is to use the var_dump() function to display the contents of an array. This can help identify the values stored in the array and pinpoint any issues with the data. Another useful technique is to use a foreach loop to iterate through the array and print out each value for inspection. 

// Example array
$array = [1, 2, 3, 4, 5];

// Using var_dump() to display array values
var_dump($array);

// Using a foreach loop to iterate through the array and print out values
foreach ($array as $value) {
    echo $value . "<br>";
}
