PHP上傳圖片的簡單例子(入門參考)

複製代碼 2、admin_upfile.php date_default_timezone_set('PRC'); //這裡上傳 $upsize判斷上傳檔案的大小 $uppath = isset($_REQUEST["upPath"]) ? $_REQUEST["upPath"] : "/attached/"; //檔案上傳路徑 $formName = isset($_REQUEST["formName"]) ? $_REQUEST["formName"] : "myform"; //回傳到上頁面編輯框所在Form的Name $editName = isset($_REQUEST["editName"]) ? $_REQUEST["editName"] : $_REQUEST["editName"]; //回傳到上頁面編輯框的Name //轉換根目錄的路徑 if (strpos($uppath, "/") == 0) { $i = 0; $thpath = $_SERVER["SCRIPT_NAME"]; $thpath = substr($thpath, 1, strlen($thpath)); while (strripos($thpath, "/") !== false) { $thpath = substr($thpath, strpos($thpath, "/") + 1, strlen($thpath)); $i = ++$i; } $pp = ""; for ($j = 0; $j < $i; ++$j) { $pp .="../"; } $uppaths = $pp . substr($uppath, 1, strlen($thpath)); } $filename = date("y-m-d"); if (is_dir($uppaths . $filename) != TRUE) mkdir($uppaths . $filename, 0777); // if(is_dir($filename."/".$ctime)!=TRUE) mkdir($filename."/".$ctime,0777); $f = $_FILES['file1']; if ($f["type"] != "image/gif" && $f["type"] != "image/pjpeg" && $f["type"] != "image/jpeg" && $f["type"] != "image/x-png") { echo ""; //echo $f['type']; return false; } //獲得副檔名 $temp_arr = explode(".", $f["name"]); $file_ext = array_pop($temp_arr); $file_ext = trim($file_ext); $file_ext = strtolower($file_ext); //新檔案名稱 $new_file_name = md5(date("YmdHis")) . '.' . $file_ext; //$new_file_name = md5(date("YmdHis") . '_' . rand(10000, 99999)) . '.' . $file_ext; $dest = $uppaths . $filename . "/" . date("ymdhis") . "_" . $new_file_name; //設定檔案名稱為日期加上檔案名稱避免重複 上傳目錄 $dest1 = $uppath . $filename . "/" . date("ymdhis") . "_" . $new_file_name; //設定檔案名稱為日期加上檔案名稱避免重複 $r = move_uploaded_file($f['tmp_name'], $dest); if ($f['size'] > 0) { echo ""; echo ""; } ?> 複製代碼 3、admin_upload.php 圖片上傳_bbs.it-home.org $uppath = isset($_REQUEST["upPath"]) ? $_REQUEST["upPath"] . "/" : "/attached/"; //檔案上傳路徑 $formName = isset($_REQUEST["formName"]) ? $_REQUEST["formName"] : "myform"; //回傳到上頁面編輯框所在Form的Name $editName = isset($_REQUEST["editName"]) ? $_REQUEST["editName"] : $_REQUEST["editName"]; //回傳到上頁面編輯框的Name ?> 複製代碼
