圖片上傳網站 php 圖片上傳類別程式碼

先來個簡單的：

複製程式碼 程式碼如下:

//http://www .jb51.net
class upLoad{
public $length; //限定檔案大小
public $file; //判斷此類是用於圖片上傳還是檔案上傳
public $fileName; / /檔案名稱
public $fileTemp; //上傳暫存檔案
public $fileSize; //上傳檔案大小
public $error; //上傳檔案有錯,php4沒有
public $fileType ; //上傳檔案類型
public $directory; //
public $maxLen;
public $errormsg;
function __construct($length,$file=true,$directory)
{
$this->maxLen=$length;
$this->length=$length*1024;
$this->file=$file; //true為一般文件，false為圖片的判斷
$this->directory=$directory;
}
public function upLoadFile($fileField)
{
$this->fileName=$fileField['name'];
$this->fileTemp=$fileField['tmp_name'];
$this->error=$fileField['error'];
$this->fileType=$fileField['type'];
$this->fileSize=$fileField['size'];
$pathSign = DIRECTORY_SEPARATOR; // /
if($this->file) //一般檔案上傳
{
$ path = $this->_isCreatedDir($this->directory);//取得路徑
if($path)//http://www.jb51.net
{
$createFileType = $this ->_getFileType($this->fileName);//設定檔類別
$createFileName=uniqid(rand()); //隨機產生檔名
$thisDir=$this->directory.$pathSign. $createFileName.".".$createFileType;
if(@move_uploaded_file($this->fileTemp,$thisDir)) //把臨時檔案移到規定的路徑下
{
return $thisDir;
}
}
}else{ //圖片上傳
$path = $this->_isCreatedDir($this->directory);//取得路徑
if($path)/ /路徑存在//http://www.jb51.net
{
$createFileType = $this->_getFileType($this->fileName);//設定檔案類別
$createFileName=uniqid( rand());
return @move_uploaded_file($this->fileTemp,$this->directory.$pathSign.$createFileName.".".$createFileType) ? true : false;
}
}
}
public function _isBig($length,$fsize) //傳回檔案是否超過規定大小
{
return $fsize>$length ? true : false;
}
public function _getFileType($fileName) //取得檔案的字尾
{
return end(explode(".",$fileName));
}
public function _isImg($fileType) //上傳圖片類型是否允許
{
$type=array("jpeg","gif","jpg","bmp");
$fileType=strtolower($fileType);
$ fileArray=explode("/",$fileType);
$file_type=end($fileArray);
return in_array($file_type,$type);//http://www.jb51.net
}
public function _isCreatedDir($path) //路徑是否存在，不存在就建立
{
if(!file_exists($path))
{
return @mkdir($ path,0755)?true:false; //權限755//
}
else
{
return true;
}
}
public function showError() showError()/Error()/Error( /顯示錯誤訊息
{//http://www.jb51.net
echo " n";
exit();
}
}
class multiUpLoad extends upLoad{
public $FILES;
function __construct($arrayFiles,$length>function __construct($arrayFiles,$length>function __construct($arrayFiles,$length. ,$file=true,$directory)
{
$this->FILES=$arrayFiles;
parent::__construct($length,$file,$directory);
}
function upLoadMultiFile()
{
$arr=array();
if($this->_judge()||$this->_judge()=="no") //檔案全部符合規格,就開始上傳
{
foreach($this->FILES as $key=>$value)
{
$strDir=parent::upLoadFile($this->FILES[$key ]);
array_push($arr, $strDir);
}
//http://www.jb51.net
return $arr;
}else
{
return false;
}
}
function _judge()
{
if($this->file)
{
foreach($this->FILES as $key=>$value)
{
if($this->_isBig($this->length,$value['size']))
{
$this->errormsg= "檔案超過$this->maxLen K";
parent::showError();
}
if($value['error']=UPLOAD_ERR_NO_FILE)
{
//$$ this->errormsg="上傳檔案出現錯誤";
//parent::showError();
return "no";
}
}
return true;
} else
{
//http://www.jb51.net
foreach($this->FILES as $key=>$value)
{
if($this-> _isBig($this->length,$value['size']))
{
$this->errormsg="圖片超過$this->maxLen";
parent::showError();
}
if($value['error']!=0)
{
$this->errormsg="上傳圖片出現錯誤";
parent::showError();
}
if(!$this->_isImg($value['type']))
{
$this->errormsg="圖片格式不對";
parent:: showError();
}
}
return true;
}
}
}
?>

再來個複雜點的，可以自動產生縮圖的功能的php上傳類別
開始第一步：
建立資料夾，版面：
annex：附件（目錄下存放上傳的原圖）
|— smallimg：存放縮圖
|— mark：存放浮水印圖片
include：存放類別文件，字體（本程式碼使用的是：04B_08__.TTF）
| — upfile.php：整合簡單上傳，產生縮圖及浮水印的類別檔案資訊
|— 04B_08__.TTF：字型檔案
test.php：測試檔案
第二步上傳類別

複製程式碼 程式碼如下:

class UPImages {
var $annexFolder = "annex";//附件存放點，預設為：annex
var $smallFolder = "smallimg";//縮略圖存放路徑，註：必須是放在$annexFolder下的子目錄，預設為：smallimg
var $markFolder = "mark";//水印圖片存放處
var $upFileType = "jpg gif png" ;//上傳的類型，預設為：jpg gif png rar zip
var $upFileMax = 1024;//上傳大小限制，單位是“KB”，預設為：1024KB
var $fontType;//字體
var $maxWidth = 500; //圖片最大寬度
var $maxHeight = 600; //圖片最大高度
function UPImages($annexFolder,$smallFolder,$includeFolder) {
this-🎜>this- >annexFolder = $annexFolder;
$this->smallFolder = $smallFolder;
$this->fontType = $includeFolder."/04B_08__.TTF";
}
function upad {
$imageName = time();//設定目前時間為圖片名稱
if(@empty($_FILES[$inputName]["name"])) die(error("沒有上傳圖片訊息，請確認"));
$name = explode(".",$_FILES[$inputName]["name"]);//將上傳前的檔案以「.」分開取得檔案類型
$imgCount = count($name);//取得截取的數量
$imgType = $name[$imgCount-1];//取得檔案的型別
if(strpos($this->upFileType,$ imgType) === false) die(error("上傳檔案類型僅支援".$this->upFileType." 不支援".$imgType));
$photo = $imageName.".".$imgType ;//寫入資料庫的檔案名稱
$uploadFile = $this->annexFolder."/".$photo;//上傳後的檔案名稱
$upFileok = move_uploaded_file($_FILES[$inputName][ "tmp_name"],$uploadFile);
if($upFileok) {
$imgSize = $_FILES[$inputName]["size"];
$kSize = round($imgSize/1024);
if($kSize > ($this->upFileMax*1024)) {
@unlink($uploadFile);
die(error("上傳檔案超過".$this->upFileMax."KB "));
}
} else {

}
return $photo;
