cURL crawls the page to crawl the web page information and replace it

Replace page information

<?php
$curlobj = curl_init();          // 初始化
curl_setopt($curlobj, CURLOPT_URL, "http://www.baidu.com");       // 设置访问网页的URL
curl_setopt($curlobj, CURLOPT_RETURNTRANSFER, true);         // 执行之后不直接打印出来
$output=curl_exec($curlobj);   // 执行
curl_close($curlobj);        // 关闭cURL
echo str_replace("百度","php",$output);
?>

Open on the web page, the effect is as follows

In this way, we have completed the replacement of the obtained page content.
