Two basic examples of php CURL

Start the preparation work. First, find extension=php_curl.dll in the php.ini file, remove the ";" in front of it, and enable curl support.

curl_init(); // Initialize curl
curl_close(); //Relationship curl
curl_exec(); //Perform curl operation
curl_setopt(int ch, string option, value) //Set curl options
option is the desired attribute, value is the corresponding value

---

option’s basic attributes are as follows:
CURLOPT_URL //Set the address to crawl the web page
CURLOPT_POST //Use php to perform httppost operation and set the option to a non-zero value
CURLOPT_POSTIELDS //All data of post operation of httppost operation
CURLOPT_PETURNTRANSFER //Whether to return the content obtained from the page, if the selected value is non-zero

One: Basic example

<code><span>$curl</span> = curl_init();                            <span>//</span>初始化curl对象
<span>$curl_setopt</span>(<span>$curl</span>,<span>CURLOPT_URL</span>,<span>'www.baidu.com'</span>);  <span>//</span>设置抓取页面的地址
<span>$curl_setopt</span>(<span>$curl</span>,<span>CURLOPT_HEADER</span>,<span>1</span>);   <span>//</span>把一个头部包含在其中输出，值要设为非零
<span>$response</span> = curl_exec(<span>$curl</span>);           <span>//</span>执行操作，运行curl
curl_close(<span>$curl</span>);                     <span>//</span>关闭操作 </code>

Two: post data

<code><span>$data</span> = <span>array</span>(<span>'name'</span>=><span>'trany'</span>,<span>'age'</span>=><span>'12'</span>);
<span>$curl</span> = curl_init();              <span>//初始化curl对象</span><span>$curl_setopt</span>(<span>$curl</span>,CURLOPT_URL,<span>'WWW.BAIDU.COM'</span>);   <span>//设置页面抓取地址</span><span>$curl_setopt</span>(<span>$curl</span>,CURLOPT_POST,<span>1</span>);                <span>//做httppost提交</span><span>$curl_setopt</span>(<span>$curl</span>,CURLOPT_POSTFIELDS,<span>$data</span>);      <span>//传递值</span><span>$response</span> = curl_exec(<span>$curl</span>);                     <span>//执行操作</span>
curl_close(<span>$curl</span>);                               <span>//关闭操作</span></code>

The above introduces two basic examples of php CURL, including aspects of content. I hope it will be helpful to friends who are interested in PHP tutorials.
