我有一个上传多个文件的表单。我正在使用的 php 代码工作正常,但我也想重命名文件并且不知道如何去做。我认为在名称中添加时间戳将是最好的答案。这是到目前为止的工作代码:
/* FILE UPLOAD CODE */
{
$number_of_file_fields = 0;
$number_of_uploaded_files = 0;
$number_of_moved_files = 0;
$uploaded_files = array();
$upload_directory = dirname(__file__) . '/uploads/'; //set upload directory
/**
* we get a $_FILES['file'] array ,
* we procee this array while iterating with simple for loop
* you can check this array by print_r($_FILES['file']);
*/
for ($i = 0; $i < count($_FILES['file']['name']); $i++) {
$number_of_file_fields++;
if ($_FILES['file']['name'][$i] != '') { //check if file field empty or not
$number_of_uploaded_files++;
$uploaded_files[] = $_FILES['file']['name'][$i];
if (move_uploaded_file($_FILES['file']['tmp_name'][$i], $upload_directory . $_FILES['file']['name'][$i])) {
$number_of_moved_files++;
}
}
}
}
/* END FILE UPLOAD CODE */
任何关于添加什么以及在哪里完成此操作的帮助将不胜感激。
