php 用 curl 获取网页内容时的乱码解决 办法

1. 直接在curl 请求的代码中添加一行代码

curl_setopt($ch, CURLOPT_ENCODING, 'gzip,deflate');

整体的curl代码如下：

function geturl1($url){

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_HTTPHEADER,array('Accept-Encoding: gzip, deflate'));
    curl_setopt($ch, CURLOPT_ENCODING, 'gzip,deflate');
    curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/71.0.3578.80 Safari/537.36");
    //函数中加入下面这条语句
    curl_setopt($ch, CURLOPT_COOKIEJAR, './cookie.txt');
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($ch, CURLOPT_TIMEOUT, 30);
    $output = curl_exec($ch);
    curl_close($ch);
    return $output;
}
