PHP/GD Library Imagettftext將圖像保存在服務器上併發送到瀏覽器

Question

我使用GD覆蓋圖像上的一些文本（已經在我的服務器上）。我試圖將新圖像保存在服務器上。

下面是我的代碼，但它所做的只是向瀏覽器顯示新圖像，並不會將其保存到服務器。

 <? 
//PHP's GD class functions can create a variety of output image 
    //types, this example creates a jpeg 
    header("Content-Type: image/jpeg"); 

    $im = imagecreatefromjpeg($image_full); 

    $black = ImageColorAllocate($im, 255, 255, 255); 


    $copy_1_x = 10; 
    $copy_1_y = 20; 

    $copy_2_x = 10; 
    $copy_2_y = 20; 

    $copy_3_x = 10; 
    $copy_3_y = 20; 

    //writes text to image 
    Imagettftext($im, 12, 0, $copy_1_x, $copy_1_y, $black, 'verdana.ttf', $main_number); 
    Imagettftext($im, 12, 0, $copy_2_x, $copy_2_y, $black, 'verdana.ttf', $prime_number); 
    Imagettftext($im, 12, 0, $copy_3_x, $copy_3_y, $black, 'verdana.ttf', $legal); 

    //Creates the jpeg image and sends it to the browser 
    //100 is the jpeg quality percentage 
    Imagejpeg($im, '', 100); 


    ImageDestroy($im); 



     ?>

由於@Ignacio

Imagejpeg($im, '/path_to_folder/imagename.jpg', 100);
