从远程源下载图像并调整大小然后保存 [英] download image from remote source and resize then save

问题描述

你们中有人知道我可以使用它来从远程源下载图像，将其大小调整为120x120并使用我选择的文件名保存它吗?

Do any of you know of a good php class I can use to download an image from a remote source, re-size it to 120x120 and save it with a file name of my choosing?

因此，基本上，我将在"http://www.site.com/image.jpg"上拥有一个图像，并以120x120像素的格式保存到我的网络服务器"/images/myChosenName.jpg"中.

So basically I would have an image at "http://www.site.com/image.jpg" save to my web server "/images/myChosenName.jpg" as a 120x120 pixels.

谢谢

推荐答案

您可以尝试以下操作:

<?php    
$img = file_get_contents('http://www.site.com/image.jpg');

$im = imagecreatefromstring($img);

$width = imagesx($im);

$height = imagesy($im);

$newwidth = '120';

$newheight = '120';

$thumb = imagecreatetruecolor($newwidth, $newheight);

imagecopyresized($thumb, $im, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);

imagejpeg($thumb,'/images/myChosenName.jpg'); //save image as jpg

imagedestroy($thumb); 

imagedestroy($im);
?>
