phpcms图片自动压缩功能

phpcms图片自动压缩功能
在公共类中写一个自动压缩的方法：

phpcms\libs\functions\extention.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){

$imgPath = PHPCMS_PATH . trim($imgPath=PHPCMSP​ATH.trim(imgName, ‘/’);

$Patharray = explode(’/’, $imgName);
$fileName = end($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/";
$dirPath = PHPCMS_PATH.$dirPath=PHPCMSP​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/’ . $fileName; if (file_exists($fileName;if(filee​xists(thumbPath)) {
return APP_PATH . ‘uploadfile/thumb/’ . $fileName;
}else{
$src = imagecreatefromjpeg($src=imagecreatefromjpeg(imgPath);
$src_w = imagesx($srcw​=imagesx(src);
$src_h = imagesy($srch​=imagesy(src);
//设置缩略图大小
$dst_w = $src_w1;
$dst_h = $src_h1;
$dst = imagecreatetruecolor($dst=imagecreatetruecolor(dst_w,$dst_h); //图片采样复制 imagecopyresampled($dsth​);//图片采样复制imagecopyresampled(dst,$src,0,0,0,0,$src,0,0,0,0,dst_w,$dst_h,$dsth​,src_w,$src_h); //保存缩略图 imagejpeg($srch​);//保存缩略图imagejpeg(dst,$thumbPath); //销毁资源 imagedestroy($thumbPath);//销毁资源imagedestroy(src);
imagedestroy($dst);
$thumbPath = str_replace(PHPCMS_PATH,"/",$thumbPath=strr​eplace(PHPCMSP​ATH,"/",thumbPath);
return $thumbPath;
}
}

在html页面中直接调用

{compress ($rs[‘thumb’])}
