What are some strategies for handling nested arrays in PHP to avoid errors and improve code performance?

Handling nested arrays in PHP can be challenging as it requires careful traversal and manipulation of the data structure. One way to avoid errors and improve code performance is by using recursive functions to iterate through the nested arrays and perform operations. This approach ensures that each level of the nested array is processed correctly and efficiently. 

function processNestedArray($array) {
    foreach ($array as $key => $value) {
        if (is_array($value)) {
            $array[$key] = processNestedArray($value);
        } else {
            // Perform operations on the non-array value
        }
    }
    return $array;
}

// Example usage
$nestedArray = [
    'key1' => 'value1',
    'key2' => [
        'key3' => 'value3',
        'key4' => [
            'key5' => 'value5'
        ]
    ]
];

$processedArray = processNestedArray($nestedArray);
