要實現多檔案上傳，我們可以在form表單中添加多個input file域，然後將這些input file的name屬性設定為相同的名稱且使用數組的形式命名，例如filename[]。至於檔案上傳的php代碼和單個檔案上傳是一樣的道理。
下面看一個多檔案上傳的執行個體：
html檔案example.html
<!DOCTYPE html><html><head><meta charset="UTF-8"></head><body><form action="my_parser.php" method="post" enctype="multipart/form-data"> <p><input type="file" name="file_array[]"></p> <p><input type="file" name="file_array[]"></p> <p><input type="file" name="file_array[]"></p> <input type="submit" value="Upload all files"></form></body></html>
php檔案my_parser.php
<?phpif(isset($_FILES['file_array'])){ $name_array = $_FILES['file_array']['name']; $tmp_name_array = $_FILES['file_array']['tmp_name']; $type_array = $_FILES['file_array']['type']; $size_array = $_FILES['file_array']['size']; $error_array = $_FILES['file_array']['error']; for($i = 0; $i < count($tmp_name_array); $i++){ if(move_uploaded_file($tmp_name_array[$i], "test_uploads/".$name_array[$i])){ echo $name_array[$i]." upload is complete<br>"; } else { echo "move_uploaded_file function failed for ".$name_array[$i]."<br>"; } }}?>
