代码如下:
function upload($file,$path,$type){
$state = array();
$state['error'] = "true";
$alltype = ""; // 所有可以上传的类型,用"/"连接起来
$path = trim($path);
//为$path末尾加上"/"
if(strlen(strrchr($path,‘/‘)) <= 1){
$path .= "/";
}
//为类型加上开头“.”
//将所有类型合成字符串,用"/"连接起来
foreach($type as $key=>$typeone){
$type[$key] = $typeone = trim($typeone);
if(strlen(strchr($typeone,".")) != strlen($typeone)){
$type[$key] = ".".$typeone;}
$alltype .= $typeone.‘/‘;
}
$alltype = substr($alltype,0,strlen($alltype)-1); //去掉最后的“/”
if(empty($file['name'])){
$state['error'] = "没有上传{$alltype}类型文件!";
$state['errorid'] = 8;
return $state;
} else {
if (!$file['error']) {
$state['name'] = $file['name'];
$state['type'] = strrchr($state['name'],‘.‘);
if(in_array($state['type'],$type)){
$time = date("U");
$state['upname'] = $time.rand(1000,9999).$state['type']; //文件命名
if(copy($file['tmp_name'],$path.$state['upname'])){
$state['time'] = date("U"); //上传的时间
$state['error'] = false;
return $state;
} else {
switch($file(‘error‘)){
case 1: $state['error'] = $state['name']."上传失败,文件大小超出了服务器的空间大小!";$state['errorid'] = 1;return $state;
case 2: $state['error'] = $state['name']."上传失败,要上传的文件大小超出浏览器限制!";$state['errorid'] = 2;return $state;

}
