Are there any specific PHP functions or methods recommended for handling multiple file uploads efficiently?

When handling multiple file uploads in PHP, it's recommended to use the `$_FILES` superglobal array to access the uploaded files and then process them accordingly. One efficient way to handle multiple file uploads is to use a loop to iterate through each file and perform necessary operations like validation, moving files to a specific directory, and storing file information in a database if needed.

if(isset($_FILES['files'])){
    $file_array = reArrayFiles($_FILES['files']);
    
    foreach($file_array as $file){
        // Perform operations on each file such as validation, moving files, etc.
        $file_name = $file['name'];
        $file_tmp = $file['tmp_name'];
        
        // Example: move uploaded files to a specific directory
        move_uploaded_file($file_tmp, 'uploads/' . $file_name);
    }
}

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;
}
