phpcms怎么压缩图片

phpcms图片自动压缩功能

在公共类中写一个自动压缩的方法：phpcmslibsfunctionsextention.func.php**@param $imgName@return mixed|string$imgpath 原图存放地址$thumbpath 压缩后图片存放路径*/function compress ($imgName){imgPath=PHPCMSPATH.trim(imgPath = PHPCMS_PATH . trim(imgPath=PHPCMS P ATH.trim(imgName, ‘/’);$Patharray = explode(’/’, $imgName);fileName=end(fileName = end(fileName=end(Patharray);//创建thumb文件夹,保存压缩后的图片header(“Content-type:text/html;charset=utf-8”);$path="/uploadfile/thumb/";dirPath=PHPCMSPATH.dirPath = PHPCMS_PATH.dirPath=PHPCMS P ATH.path;if(!is_dir(KaTeX parse error: Expected '}', got 'EOF' at end of input: …h)){ mkdir(dirPath,0777,true);}$thumbPath = PHPCMS_PATH . ‘uploadfile/thumb/’ . fileName;if(fileexists(fileName;if (file_exists(fileName;if(file e xists(thumbPath)) {return APP_PATH . ‘uploadfile/thumb/’ . $fileName;}else{src=imagecreatefromjpeg(src = imagecreatefromjpeg(src=imagecreatefromjpeg(imgPath);srcw=imagesx(src_w = imagesx(src w =imagesx(src);srch=imagesy(src_h = imagesy(src h =imagesy(src);//设置缩略图大小$dst_w = $src_w1;$dst_h = $src_h1;dst=imagecreatetruecolor(dst = imagecreatetruecolor(dst=imagecreatetruecolor(dst_w,dsth);//图片采样复制imagecopyresampled(dst_h);//图片采样复制imagecopyresampled(dst h );//图片采样复制imagecopyresampled(dst,src,0,0,0,0,src,0,0,0,0,src,0,0,0,0,dst_w,dsth,dst_h,dst h ,src_w,srch);//保存缩略图imagejpeg(src_h);//保存缩略图imagejpeg(src h );//保存缩略图imagejpeg(dst,thumbPath);//销毁资源imagedestroy(thumbPath);//销毁资源imagedestroy(thumbPath);//销毁资源imagedestroy(src);imagedestroy($dst);thumbPath=strreplace(PHPCMSPATH,"/",thumbPath = str_replace(PHPCMS_PATH,"/",thumbPath=str r eplace(PHPCMS P ATH,"/",thumbPath);return $thumbPath;}}

在html页面中直接调用{compress ($rs[‘thumb’])}以上就是phpcms怎么压缩图片的详细内容，更多请关注小潘博客其它相关文章！
