示例代码:
public function img(){ $img = "http://static.hc39.com/uploads/309/t11332950.jpg"; $info = getimagesize($img); $imgExt = image_type_to_extension($info[2], false); //获取文件后缀 $fun = "imagecreatefrom{$imgExt}"; $imgInfo = $fun($img); //1.由文件或 URL 创建一个新图象。如:imagecreatefrompng ( string $filename ) //$mime = $info['mime']; $mime = image_type_to_mime_type(exif_imagetype($img)); //获取图片的 MIME 类型 header('Content-Type:'.$mime); $quality = 100; if($imgExt == 'png') $quality = 9; //输出质量,JPEG格式(0-100),PNG格式(0-9) $getImgInfo = "image{$imgExt}"; $getImgInfo($imgInfo, null, $quality); //2.将图像输出到浏览器或文件。如: imagepng ( resource $image ) imagedestroy($imgInfo); }
img标签的SRC可以直接写这个地址:
<img src="http://www.fyzthink.com/index.php?s=/Index/img.html">
