php的curl模块采集任意网页
使用PHP的curl库可以方便地实现网页抓取功能。通过curl库,我们可以发送HTTP请求并获取服务器响应的内容。以下是一个使用php curl抓取页面所有链接的方法:
1. 创建一个curl资源句柄:
```
$ch = curl_init();
```
2. 设置curl选项,包括目标URL、请求头信息和其他参数:
```
curl_setopt($ch, CURLOPT_URL, "目标URL");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (iPhone; CPU iPhone OS 8_0 like Mac OS X) AppleWebKit/600.1.3 (KHTML, like Gecko) Version/8.0 Mobile/12A4345d Safari/600.1.4");
```
其中,`CURLOPT_URL`用于设置目标URL,`CURLOPT_RETURNTRANSFER`用于设置是否将抓取的内容作为字符串返回,`CURLOPT_FOLLOWLOCATION`用于设置是否跟随重定向,`CURLOPT_USERAGENT`用于设置用户代理。
3. 执行curl请求并获取响应内容:
```
$response = curl_exec($ch);
```
4. 使用正则表达式或其他方法从响应内容中提取所有链接:
```
preg_match_all('/<a\s+href=["\'](.*?)["\']/', $response, $matches);
$links = $matches<span class="em">1</span><span class="em">2</span><span class="em">3</span>
