我正在尝试将视频上传到本地主机上的 PHP 服务器。我已成功上传图像和文本文件,但相同的代码不适用于视频。请告诉我这段代码有什么问题。

这是服务器端脚本:

<?php
$mysql_host = "localhost";
$mysql_database = "test";
$mysql_user = "root";
$mysql_password = "";
$con = mysql_connect($mysql_host, $mysql_user, $mysql_password);
mysql_select_db($mysql_database) or die("Unable to select database");
$target_path = "uploads/";
$target_path = $target_path . basename( $_FILES['uploadedfile']['name']);
echo $target_path;
if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
echo "The file ". basename( $_FILES['uploadedfile']['name']).
  " has been uploaded";
$sql="insert into images set url='$target_path'";
mysql_query($sql);
} else{
echo "There was an error uploading the file, please try again!";
}
?>

这是客户端代码:

将php.ini中的upload_max_filesize的值更改为所需的限制,默认为 2M
