php中使用gd库实现远程图片下载实例_php实例
因为今天想写个远程下载图片的类,提前热身写了个php gd库实现远程图片下载功能,当然curl实现更好,php gd库实现远程图片下载功能主要使用gd库的两个函数ImageCreateFromXXX()用于生成图片函数和ImageXXX函数,XXX表示不同图片的扩展名,所以你要想办法获取远程图片的扩展名了,附上php代码如下:
<?php header("Content-type:text/html ; charset=utf-8"); if (!empty($_POST['submit'])){ $url = $_POST['url']; $pictureName = $_POST['pictureName']; $img = getPicture($url,$pictureName); echo '<pre class="brush:php;toolbar:false"><img src="/static/imghw/default1.png" data-src="'.$img.'" class="lazy".$img.'" alt="php中使用gd库实现远程图片下载实例_php实例" >
运行结果如下图:(图片自动保存在当前文件目录,不明白的可以留言)
