PHP获取远程图片并保存到本地的方法,
本文实例讲述了PHP获取远程图片并保存到本地的方法。分享给大家供大家参考。具体实现方法如下:
<?php function GrabImage($url, $filename = "") { if ($url == ""):return false; endif; //如果$url地址为空,直接退出 if ($filename == "") { //如果没有指定新的文件名 $ext = strrchr($url, "."); //得到$url的图片格式 if ($ext != ".gif" && $ext != ".jpg"):return false; endif; //如果图片格式不为.gif或者.jpg,直接退出 $filename = date("dMYHis") . $ext; //用天月面时分秒来命名新的文件名 } ob_start();//打开输出 readfile($url);//输出图片文件 $img = ob_get_contents();//得到浏览器输出 ob_end_clean();//清除输出并关闭 $size = strlen($img);//得到图片大小 $fp2 = @fopen($filename, "a"); fwrite($fp2, $img);//向当前目录写入图片文件,并重新命名 fclose($fp2); return $filename;//返回新的文件名 } $img = GrabImage("http://imgsrc.baidu.com/baike/abpic/item/6648d73db0edd1e89f3d62f7.jpg", ""); if ($img):echo '<pre class="brush:php;toolbar:false"><img src="' . $img . '" alt="PHP获取远程图片并保存到本地的方法," >'; //如果返回值为真,这显示已经采集到服务器上的图片 else:echo "false"; endif; //否则,输出采集失败 ?>
希望本文所述对大家的php程序设计有所帮助。
