phpcms怎么压缩图片-PHPCMS

phpcms紧缩图片的办法：起首找到并关上“extention.func.php”文件；而后正在公共类中写一个主动紧缩的办法；最初经过语句“{compress ($rs[‘thumb’])}”正在html页面中间接挪用便可。

phpcms图片主动紧缩性能

正在公共类中写一个主动紧缩的办法：

phpcms\libs\functions\extention.func.php
**
@param $imgName
@return mixed|string
$imgpath 原图寄存地点
$thumbpath 紧缩后图片寄存门路
*/
function compress ($imgName){
imgPath=PHPCMSPATH.trim(imgPath = PHPCMS_PATH . trim(imgPath=PHPCMS 
P
 ATH.trim(imgName, ‘/’);
$Patharray = explode(’/’, $imgName);
fileName=end(fileName = end(fileName=end(Patharray);
//创立thumb文件夹,保留紧缩后的图片
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);
//设置缩略图巨细
$dst_w = $src_w1;
$dst_h = $src_h1;
dst=imagecreatetruecolor(dst = imagecreatetruecolor(dst=imagecreatetruecolor(dst_w,dsth);//图片采样复制imagecopyresampled(dst_h);//图片采样复制imagecopyresampled(dst 
h
 );//图片采样复制imagecopyresampled(dst,src,0,0,0,0,src,0,0,0,0,src,0,0,0,0,dst_w,dsth,dst_h,dst 
h
 ,src_w,srch);//保留缩略图imagejpeg(src_h);//保留缩略图imagejpeg(src 
h
 );//保留缩略图imagejpeg(dst,thumbPath);//销毁资本imagedestroy(thumbPath);//销毁资本imagedestroy(thumbPath);//销毁资本imagedestroy(src);
imagedestroy($dst);
thumbPath=strreplace(PHPCMSPATH,"/",thumbPath = str_replace(PHPCMS_PATH,"/",thumbPath=str 
r
 eplace(PHPCMS 
P
 ATH,"/",thumbPath);
return $thumbPath;
}
}

正在html页面中间接挪用

{compress ($rs[‘thumb’])}
