如何使用所需名称上传和保存文件

Question

我正在使用此代码上传文件（图像到文件夹）<form action='' method='POST' enctype='multipart/form-data'><input type='file' name='userFile'><br><input type='submit' name='upload_btn' value='upload'></form><?php$target_Path = "images/";$target_Path = $target_Path.basename( $_FILES['userFile']['name'] );move_uploaded_file( $_FILES['userFile']['tmp_name'], $target_Path );?>当文件（图像）保存在指定路径时...如果我想用所需的名称保存文件...我曾尝试更换此$target_Path = $target_Path.basename( $_FILES['userFile']['name'] );有了这个$target_Path = $target_Path.basename( "myFile.png" );但是它不起作用

你可以试试看

$info = pathinfo($_FILES['userFile']['name']);

$ext = $info['extension']; // get the extension of the file

$newname = "newname.".$ext; 

$target = 'images/'.$newname;

move_uploaded_file( $_FILES['userFile']['tmp_name'], $target);
