php如何實(shí)現(xiàn)文件上傳

1、創(chuàng)建表單和file類(lèi)型的input并將表單屬性“enctype”設(shè)置為“multipart/form-data”；

<form action="./upload_file.php" method="post" enctype="multipart/form-data">     <input type="file" name="upfile">     <button type="submit">上傳</button> </form>

2、在php程序中通過(guò)“move_uploaded_file”函數(shù)將提交的文件進(jìn)行保存即可。

$filename = $file_tmp = $_FILES['upfile']['name']; $file_tmp = $_FILES['upfile']['tmp_name'];  move_uploaded_file($file_tmp, 'Uploads/' . $filename);
