(PHP 4 >= 4.0.2, PHP 5, PHP 7, PHP 8)
curl_close — 关闭 cURL 会话
注意:
此函数无效。在 PHP 8.0.0 之前，用于关闭资源。
关闭 cURL 会话并且释放所有资源。也会删除 cURL 句柄 handle。
没有返回值。
| 版本 | 说明 |
|---|---|
| 8.0.0 |
handle 现在接受 CurlHandle
实例；之前接受 resource。

示例 #1 初始化新 cURL 会话并获取网页
<?php
// 创建新 cURL 资源
$ch = curl_init();
// 设置 URL 和相应的选项
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");
curl_setopt($ch, CURLOPT_HEADER, 0);
// 抓取 URL 并把它传递给浏览器
curl_exec($ch);
// 关闭 cURL 资源，并且释放系统资源
curl_close($ch);
?>Although the Note for this call says "Prior to PHP 8.0.0, this function was used to close the resource", I found that PHP 7.4.33 on CentOS is not closing the connection on curl_close.
The workaround if you want to make sure the connection closes immediately after the request is to set the curl option to forbid reuse:
curl_setopt($curl, CURLOPT_FORBID_REUSE, TRUE);
