php多文件上传实现代码
index_uploads.php
<html>
<head>
<meta charset="utf-8">
<title>index_uploads</title>
</head>
<body>
<form action="uploads.php" method="post" enctype="multipart/form-data">
<input type="file" name="file[]">
<br>
<input type="file" name="file[]">
<br>
<input type="submit" value="uploads">
</form>
</body>
</html>
uploads.php
<?php
header("content-type:text/html;charset=utf-8");
echo "<pre>";
print_r($_files);
echo "</pre>";
$count = count($_files['file']['name']);
for ($i = 0; $i < $count; $i++) {
$tmpfile = $_files['file']['tmp_name'][$i];
$filefix = array_pop(explode(".", $_files['file']['name'][$i]));
$dstfile = "uploads/files/".time()."_".mt_rand().".".$filefix;
if (move_uploaded_file($tmpfile, $dstfile)) {
echo "<script>alert('succeed!');window.location.href='index_uploads.php';</script>";
} else {
echo "<script>alert('fail!');window.location.href='index_uploads.php';</script>";
}
}
核心：<1>上传首页中input的name属性是这么设置的。
<2>用while循环上传多文件。
