这是您正确的代码。您可以在移动时重命名文件。
<?php
ini_set('post_max_size', '40M');
ini_set('upload_max_filesize', '40M');
if (isset($_POST['do']) and $_POST['do'] == 'upload') {
$filename = $_FILES['file']['name'];
$filesize = $_FILES['file']['size'];
$tmp_name = $_FILES['file']['tmp_name'];
$file_type = $_FILES['file']['type'];
$date = date("d-m-Y_H-i");
$temp = explode(".", $filename);
$new_filename = $temp[0] . '-' . $date . '.' . end($temp);
$f_folder = "uploads" . DIRECTORY_SEPARATOR . $new_filename;
if (empty($filename)) {
echo "choose file please";
} else {
move_uploaded_file($tmp_name, $f_folder);
echo "file is uploaded in " . $f_folder;
}
};
echo "
<form method='post' enctype='multipart/form-data' >
File Path : <input type='file' name='file' />
<br>
<input type='submit' name='do' value='upload' />
</form>";
?>

您的代码已损坏。在用户提交表单之前,您无法从$_FILES
获取任何变量,$_POST["do"]
(提交)的值始终为&#34;上传&#34;。有些托管公司不允许您使用move_uploaded_file()
,但不用担心,您可以使用rename()
。首先移动文件,然后使用rename()
对其进行重命名。并且你不应该只是将文件大小设置为变量而不用它做任何事情,你也应该检查它,以避免在不告诉用户任何事情的情况下拒绝过大的文件。
