一些常用PHP语句，适用在ThinkPHP5上(1)

1.发送GET/POST请求

/**
 * 发送post请求
 * @author 翟翟
 * @param string $url 请求地址
 * @param array $data post键值对数据
 * @return string
 */
function curl_post_https($url,$data){ // 模拟提交数据函数
    $headers=array('Content-Type: application/json');

    curl_setopt($curl, CURLOPT_URL, $url); // 要访问的地址
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0); // 对认证证书来源的检查
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 0); // 从证书中检查SSL加密算法是否存在
    curl_setopt($curl, CURLOPT_USERAGENT, 'Opera/9.80 (Windows NT 6.2; Win64; x64) Presto/2.12.388 Version/12.15'); // 模拟用户使用的浏览器
    curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1); // 使用自动跳转
    curl_setopt($curl, CURLOPT_AUTOREFERER, 1); // 自动设置Referer
    curl_setopt($curl, CURLOPT_POST, 1); // 发送一个常规的Post请求
    curl_setopt($curl, CURLOPT_POSTFIELDS, $data); // Post提交的数据包
    curl_setopt($curl, CURLOPT_TIMEOUT, 30); // 设置超时限制防止死循环
    curl_setopt($curl, CURLOPT_HEADER, 0); // 显示返回的Header区域内容
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); // 获取的信息以文件流的形式返回
    curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
    $tmpInfo = curl_exec($curl); // 执行操作
    if (curl_errno($curl)) {
        echo 'Errno'.curl_error($curl);//捕抓异常
    }
    curl_close($curl); // 关闭CURL会话
    return $tmpInfo; // 返回数据，json格式
}
/**

    $tmpInfo = curl_exec($curl);     //返回api的json对象
    //关闭URL请求
    curl_close($curl);
    return $tmpInfo;    //返回json对象
}
/**
 * 发送post请求-form方式
 * @param string $url 请求地址
 * @param array $data post键值对数据JSON格式
 * @return string
 */
function curl_post_form($url,$data){ // 模拟提交数据函数
    $postData = http_build_query($data);
    $curl = curl_init();
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_USERAGENT,'Opera/9.80 (Windows NT 6.2; Win64; x64) Presto/2.12.388 Version/12.15');
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);

    curl_setopt($curl, CURLOPT_POST, true);
    curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded'));
    curl_setopt($curl, CURLOPT_POSTFIELDS, $postData);
    curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
    $tmpInfo = curl_exec($curl); // 执行操作
    if (curl_errno($curl)) {
        echo 'Errno'.curl_error($curl);//捕抓异常
    }
    curl_close($curl); // 关闭CURL会话
    return $tmpInfo; // 返回数据，json格式
}
//第二种POST，传进来的是数组
function ccb_curl_calls($curl, $data, $https = true)
{
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_0);
    curl_setopt($ch, CURLOPT_USERAGENT,'Opera/9.80 (Windows NT 6.2; Win64; x64) Presto/2.12.388 Version/12.15');
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 300);

        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
    }
    $data = json_encode($data, JSON_UNESCAPED_UNICODE);
    $httpHeaders = array(
        'Content-Type: application/json; charset=utf-8',

        'Content-Length: ' . strlen($data)
    );

    } else if (preg_match('/Mac/i',$agent)) {
        $os = 'Mac';
    } else if (preg_match('/PowerPC/i',$agent)) {
        $os = 'PowerPC';
    } else if (preg_match('/AIX/i',$agent)) {

        $os = 'mobile';
    } else {
        $os = '未知操作系统';
    }
    return $os;
}

3.获取客户端浏览器信息

/**
 * 获取客户端浏览器信息 添加win10 edge浏览器判断
 * @return string
 */
function getBroswer()
{
    $sys = $_SERVER['HTTP_USER_AGENT'];  //获取用户代理字符串
    if (stripos($sys, "Firefox/") > 0) {
        preg_match("/Firefox\/([^;)]+)+/i", $sys, $b);
        $exp[0] = "Firefox";
        $exp[1] = $b[1];  //获取火狐浏览器的版本号
    } elseif (stripos($sys, "Maxthon") > 0) {
        preg_match("/Maxthon\/([\d\.]+)/", $sys, $aoyou);
        $exp[0] = "傲游";
        $exp[1] = $aoyou[1];
    } elseif (stripos($sys, "MSIE") > 0) {
        preg_match("/MSIE\s+([^;)]+)+/i", $sys, $ie);
        $exp[0] = "IE";
        $exp[1] = $ie[1];  //获取IE的版本号
    } elseif (stripos($sys, "OPR") > 0) {
        preg_match("/OPR\/([\d\.]+)/", $sys, $opera);
        $exp[0] = "Opera";
        $exp[1] = $opera[1];
    } elseif (stripos($sys, "Edge") > 0) {
        //win10 Edge浏览器 添加了chrome内核标记 在判断Chrome之前匹配
        preg_match("/Edge\/([\d\.]+)/", $sys, $Edge);
        $exp[0] = "Edge";
        $exp[1] = $Edge[1];
    } elseif (stripos($sys, "Chrome") > 0) {
        preg_match("/Chrome\/([\d\.]+)/", $sys, $google);
        $exp[0] = "Chrome";
        $exp[1] = $google[1];  //获取google chrome的版本号
    } elseif (stripos($sys, 'rv:') > 0 && stripos($sys, 'Gecko') > 0) {
        preg_match("/rv:([\d\.]+)/", $sys, $IE);
        $exp[0] = "IE";
        $exp[1] = $IE[1];
    } elseif (stripos($sys, 'Safari') > 0) {
        preg_match("/safari\/([^\s]+)/i", $sys, $safari);
        $exp[0] = "Safari";
        $exp[1] = $safari[1];
    } else {
        $exp[0] = "未知浏览器";
        $exp[1] = "";
    }
    return $exp[0] . '(' . $exp[1] . ')';
}

4.返回带协议的域名

/**
 * 返回带协议的域名，只适用于ThinkPHP上
 */
function get_host()
{
    $host=$_SERVER["HTTP_HOST"];
    $protocol=Request::instance()->isSsl()?"https://":"http://";
    return $protocol.$host;
}

5.强制下载

/**
 * 强制下载
 * @param string $filename 文件路径
 * @param string $content 下载页面显示内容
 */
function force_download_content($filename, $content)
{
    header("Pragma: public");
    header("Expires: 0");
    header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
    header("Content-Type: application/force-download");
    header("Content-Transfer-Encoding: binary");
    header("Content-Disposition: attachment; filename=$filename");
    echo $content;
    exit ();
}

6.返回json数据

// 返回json数据
function ajaxReturn($data){
    header('Content-Type:application/json; charset=utf-8');
    exit(json_encode($data));
}

7.关联数组转字符串

/**
 * @author 翟翟
 * 关联数组转字符串
 * @param string $split 分割符
 * @param string $array 关联数组
 * @return string 返回用分割符分割的字符串
 */
function relatearray2string($split, $array = array())
{
    if ($array) {
        foreach ($array as $key => $value) {
            $arraystr[] =$key.'='.$value;
        }
        $arraystr=implode($split,$arraystr);
        return $arraystr;
    }else{
        return '';
    }
}

---

用法：

$sl_data=array(
    'name'=>'张三',
    'age'=>'18',
);
echo relatearray2string('=',$sl_data);

输出：name=张三,age=18

---

8.自动跳转到其他服务器

$gotourl="http://www.baidu.com";
header("refresh:0;url=$gotourl");//0秒后跳转到www.baidu.com
print('<div style="width:100%;margin-top:35vh;text-align:center;">正在加载，请稍等...<br>3秒后自动跳转到新网址~~~</div>');
