How can PHP developers effectively handle and troubleshoot issues related to array manipulation and data storage in their scripts?

Issue: PHP developers can effectively handle and troubleshoot issues related to array manipulation and data storage in their scripts by using built-in array functions, error handling techniques, and proper data validation. Example PHP code snippet: 

// Example of handling array manipulation and data storage issues
$data = array('John', 'Doe', '30');
$updatedData = array_map('htmlspecialchars', $data); // Sanitize data
$serializedData = serialize($updatedData); // Serialize data for storage

// Store serialized data in a file
$fileName = 'data.txt';
$fp = fopen($fileName, 'w');
fwrite($fp, $serializedData);
fclose($fp);

// Retrieve and unserialize data from the file
$fp = fopen($fileName, 'r');
$storedData = fread($fp, filesize($fileName));
fclose($fp);

$unserializedData = unserialize($storedData); // Unserialize data
print_r($unserializedData);
