What is the best way to output an array in an email using the mail() function in PHP?

When using the mail() function in PHP to send an email with an array as part of the message body, the array needs to be converted into a string before being included in the email. This can be done by using the implode() function to concatenate the array elements into a single string. This ensures that the array is displayed correctly in the email.

php 
// Define an array
$array = array('apple', 'banana', 'cherry');

// Convert the array into a string
$arrayAsString = implode(', ', $array);

// Use the mail() function to send an email with the array as part of the message body
$to = 'recipient@example.com';
$subject = 'Array in Email';
$message = 'The array elements are: ' . $arrayAsString;
$headers = 'From: sender@example.com';

mail($to, $subject, $message, $headers);
