php下获取http状态的实现代码

逐风整理了两种方式，大家可以自行参考/使用：

复制代码 代码如下:

#方式一
$ch = curl_init('http://www.vevb.com');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_exec($ch);
echo curl_getinfo($ch, CURLINFO_HTTP_CODE); // 200
curl_close($ch);

方式二

复制代码 代码如下:

print_r(
    get_headers('http://www.baidu.com')
);
#返回以下内容：
/*
