要通过PHP的chdir函数实现文件的上传,可以按照以下步骤操作:
chdir('/path/to/upload/folder');
<form action="upload.php" method="post" enctype="multipart/form-data">
<input type="file" name="file">
<input type="submit" value="Upload">
</form>
if(isset($_FILES['file'])) {
$fileTmp = $_FILES['file']['tmp_name'];
$filename = $_FILES['file']['name'];
if(move_uploaded_file($fileTmp, $filename)) {
echo "File uploaded successfully.";
} else {
echo "Error uploading file.";
}
} else {
echo "Please select a file to upload.";
}
通过以上步骤,您可以使用PHP的chdir函数实现文件的上传。请注意确保目标文件夹有足够的权限以便上传文件。
