php實現檔案下載簡單樣本(代碼實現檔案下載)_PHP教程

複製代碼 代碼如下:
public function downloads($name){
$name_tmp = explode("_",$name);
$type = $name_tmp[0];
$file_time = explode(".",$name_tmp[3]);
$file_time = $file_time[0];
$file_date = date("Y/md",$file_time);
$file_dir = SITE_PATH."/data/uploads/$type/$file_date/";

if (!file_exists($file_dir.$name)){
header("Content-type: text/html; charset=utf-8");
echo "File not found!";
exit;
} else {
$file = fopen($file_dir.$name,"r");
Header("Content-type: application/octet-stream");
Header("Accept-Ranges: bytes");
Header("Accept-Length: ".filesize($file_dir . $name));
Header("Content-Disposition: attachment; filename=".$name);
echo fread($file, filesize($file_dir.$name));
fclose($file);
}
}

樣本2:代碼實現檔案下載

一般實現下載都是調用url來下載，但是遇到ie能識別開啟的檔案就不能用這種方式了，比如下載一個圖片、html網頁等，這時就需要編程來實現，以下php代碼可以解決：

複製代碼 代碼如下:
if( empty($_GET['FileName'])|| empty($_GET['FileDir'])|| empty($_GET['FileId'])){
echo''; exit();
}
$file_name=$_GET['FileName'];
$file_dir=$_GET['FileDir'];
$FileId=$_GET['FileId'];
$file_dir = $file_dir."/";
if (!file_exists($file_dir.$file_name)) { //檢查檔案是否存在
echo "檔案找不到";
exit;
} else {
$file = fopen($file_dir . $file_name,"r"); // 開啟檔案
// 輸入檔案標籤
Header("Content-type: application/octet-stream");
Header("Accept-Ranges: bytes");
Header("Accept-Length: ".filesize($file_dir . $file_name));
Header("Content-Disposition: attachment; filename=" . $file_name);
// 輸出檔案內容
echo fread($file,filesize($file_dir . $file_name));
fclose($file);
exit();
}
?>
