PHP上传文件

自己写的一个简单的php上传文件的实例

 

 

$uploaddir= "./upload/";
 
  //设置文件上传的目录
$uploadfile = $uploaddir.$_FILES['upfile']['name'];
$type=array("jpg","gif","bmp","jpeg","png","gz","tgz","sh","tgz");
 
  //设置允许上传文件的类型
$photo=array("jpg","gif","bmp","jpeg","png");
 
  //设置图片类型

//获取文件后缀名函数
function fileext($upfile)
{
 return substr(strrchr($upfile, '.'), 1);
}

$a=strtolower(fileext($_FILES['upfile']['name']));
//判断文件类型
if(!in_array(strtolower(fileext($_FILES['upfile']['name'])),$type))
{
 $text=implode(",",$type);
 echo "您只能上传以下类型文件: ",$text,"
";
}

print "

";
if (move_uploaded_file($_FILES['upfile']['tmp_name'], $uploaddir . $_FILES['upfile']['name']))
{
 print "文件上传成功。\n";
 system('/data/billli/bill/rsync.sh ' . $_FILES['upfile']['name']);
 print "上传的文件名：" . $_FILES['upfile']['name'] . "\n";
 print "上传的文件大小：" . $_FILES['upfile']['size'] . "\n";
 
 if(in_array(strtolower(fileext($_FILES['upfile']['name'])),$photo))
 {
  echo "您的文件已经上传完毕 上传图片预览: 
";
 }  
  
 echo"

}
else {
 print "没有成功!  下面有更多的信息:\n";
 print_r($_FILES);
}
print "
