How can PHP be optimized for processing and handling multiple file uploads efficiently?

When processing multiple file uploads in PHP, it is important to optimize the code to handle them efficiently. One way to do this is by using a loop to iterate through each file and process them individually, rather than processing them all at once. This can help prevent memory issues and improve performance. 

if(isset($_FILES['files'])){
    $file_array = reArrayFiles($_FILES['files']);
    
    foreach($file_array as $file){
        // Process each file individually
        $file_name = $file['name'];
        $file_tmp = $file['tmp_name'];
        
        // Add your file processing logic here
    }
}

function reArrayFiles($file_post) {
    $file_ary = array();
    $file_count = count($file_post['name']);
    $file_keys = array_keys($file_post);

    for ($i=0; $i<$file_count; $i++) {
        foreach ($file_keys as $key) {
            $file_ary[$i][$key] = $file_post[$key][$i];
        }
    }

    return $file_ary;
}
