What are some recommended approaches for passing arrays from PHP to a C program for execution on a website?

When passing arrays from PHP to a C program for execution on a website, one recommended approach is to use the `json_encode` function in PHP to convert the array into a JSON string. This JSON string can then be passed as a parameter to the C program using a system call or any other method of communication between PHP and C. 

// PHP code to pass an array to a C program
$array = [1, 2, 3, 4, 5];
$jsonString = json_encode($array);

// Call the C program with the JSON string as a parameter
$output = shell_exec('./your_c_program ' . escapeshellarg($jsonString));

// Process the output from the C program
echo $output;
