PHP多文件上传类实例

本文实例讲述了PHP多文件上传类。分享给大家供大家参考。具体如下：
复制代码 代码如下:<"$this->$file_name ".'文件上传失败！<br/>';break;
    }
    self::__destruct();
}else{
    $smfiletypeflag = array_search($smfiletype,$this->$file_type_array);
 
//进行真实格式验证
if($smfiletypeflag != false){
$file = fopen($this->$file_tmp_name, "rb");
$bin = fread(file, 10);
fclose($file);
$strInfo = @unpack("c10chars", $bin);
$typeCode = intval($strInfo['chars1'].$strInfo['chars2']);
$smfiletypeflag = array_search($typeCode, $this->$file_type_real_array);
if($smfiletypeflag == false){ //判断是否是png图片
$typeCode = intval($strInfo['chars2'].$strInfo['chars3'].$strInfo['chars4']);
$smfiletypeflag = array_search($typeCode, $this->$file_type_real_array);
if($smfiletypeflag == false){ //判断是否是jpg图片
$$typeCode = intval($strInfo['chars7'].$strInfo['chars8'].$strInfo['chars9'].$strInfo['chars10']);
$smfiletypeflag = array_search($typeCode, $this->$file_type_real_array);
}
}
}
 
if($smfiletypeflag == false){
$smfilemessage='<strong>文件类型不对，请核实！</strong>';
self::__destruct();
}else{
$resflag = $$this->move_file($$this->$file_tmp_name,$this->$file_name);
if ($resflag == 1){
$smfilemessage = '文件上传成功！';
$this->totalsize +=  intval($smfilesize);
self::__destruct();
}else{
$smfilemessage = '<strong>文件上传失败！</strong>';
self::__destruct();
}
}
}
 
$$smfilesizeformat = $this->size_BKM($smfilesize);
echo '<tr>
<td align="left" >'.$smfilename.'</td>
<td align="center" >'.$smfiletype.'</td>
<td align="center" >'.$smfilesizeformat.'</td>
<td align="center" >'.smfilemessage.'</td>
</tr>';
}
 
function move_file($mvfiletmp,$mvfilename){ //移动文件
$mvfilenamearr = explode('.',basename($mvfilename));
$mvfilenamearr[0] = $this->rand_string();
$mvfilename = implode('.',$mvfilenamearr);
 
if (is_uploaded_file($mvfiletmp)){
$uploadfile = self::FILE_PATH."$mvfilename";
$result = move_uploaded_file($mvfiletmp,$uploadfile);
return $result;
}
}
 
function rand_string(){
$string = md5(uniqid(rand().microtime()));
return $string;
}
 
function size_BKM($size){ // B/KB/MB单位转换
if($size < 1024)
{
$size_BKM = (string)$size . " B";
}
elseif($size < (1024 * 1024))
{
$size_BKM = number_format((double)($size / 1024), 1) . " KB";
}else
{
$size_BKM = number_format((double)($size / (1024*1024)),1)." MB";
}
return $size_BKM;
}
}
?>

希望本文所述对大家的php程序设计有所帮助。
