首先，对PHP来说视频也属于文件，我们利用这个道理，可以通过与上传普通文件类似的方式实现上传PHP视频文件。不同的是视频文件一般较大，上传时间长，而php配置文件也对上传文件的大小有限制。
<?php
//设置最多允许10个文件同时上传
define('MUILTI_FILE_UPLOAD', '10');
//设置文件大小不超过5MB
define('MAX_SIZE_FILE_UPLOAD', '500000' );
//设置上传文件的存储目录
define('FILE_UPLOAD_DIR', '/fileUploads');
//允许上传的文件扩展名
$array_extention_interdite = array( '.flv' , '.wmv' , '.rmvb' , '.php' , '.php3' , '.php4' , '.exe' , '.msi' , '.htaccess' , '.gz' );
//显示信息的公共函数
function func_message($message='', $ok=''){
echo '<table width="100%" cellspacing="0" cellpadding="0" border="0">';
if($ok == true)
echo '<tr><td width="50%"> '.$message.'</td></tr>' ;
else
echo '<tr><td width="50%"> '.$message.'</td></tr>';
echo '</table>';
}
