如何將條形碼圖像保存到計算機驅動器中的文件夾？

Question

我創建使用PHP條碼插件

HTML

<img src="barcode.php?codetype=Code128&size=50&text=123421321321321321" style="width:auto; height:auto;" alt="123456789"/> 

我怎麼能這個條碼圖像保存到本地驅動器的硬盤驅動器的條形碼？

試試這個獲取內容，並保存到文件

$barcode = file_get_contents('http://www.youdomain.com/barcode.php?codetype=Code128&size=50&text=123421321321321321'); 

//you can also use below function get more info on image 
//$imgInfo = getimagesize($barcode); 

//save the file to disk 
file_put_contents('path_to_file/code.png', $barcode); 

使用捲曲

//You can also try it using CURL if above doesn't works 

$ch = curl_init('http://www.youdomain.com/barcode.php?codetype=Code128&size=50&text=123421321321321321'); 
$fp = fopen('path_to_file/code.png', 'wb'); 
     curl_setopt($ch, CURLOPT_FILE, $fp); 
     curl_setopt($ch, CURLOPT_HEADER, 0); 
     curl_exec($ch); 
     curl_close($ch); 
fclose($fp); 

編輯barcode.php

現在，它很簡單，在文件它只是簡單地返回圖像的標題，就在您添加此行以將其保存在服務器上之前

// Save the image to file.png 
imagepng($image, "file.png"); // Your barcode will be saved here with name file.png 

// Draw barcode to the screen 
header ('Content-type: image/png'); 
imagepng($image); 
imagedestroy($image); 

希望這有助於
