本着不想从各种源码中翻来覆去找函数方法，故将已经封装好的函数方法收集，方便用时直接复制。

Header 方法

1

4
error_reporting(0);
header('Access-Control-Allow-Origin: *');
header("Content-type: text/json; charset=utf-8");
header("Content-type: text/json; charset=GB2312");

正则方法

注意 $pattern 需要界定符和转义

1
2
3
4
5
function preg($pattern, $subject, $order)
{
    preg_match_all($pattern, $subject, $_Return);
    return $order == 0 ? $_Return : $_Return[$order];
}

输出方法

1
$json = json_encode($arr, JSON_UNESCAPED_UNICODE | JSON_FORCE_OBJECT);

function curl_get($url)
{
    $oCurl = curl_init();
    if (stripos($url, "https://") !== FALSE) {
        curl_setopt($oCurl, CURLOPT_SSL_VERIFYPEER, FALSE);
        curl_setopt($oCurl, CURLOPT_SSL_VERIFYHOST, FALSE);
        curl_setopt($oCurl, CURLOPT_SSLVERSION, 1);
    }
    curl_setopt($oCurl, CURLOPT_URL, $url);
    curl_setopt($oCurl, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($oCurl, CURLOPT_COOKIE, '');
    // curl_setopt($oCurl, CURLOPT_PROXY, "127.0.0.1");
    // curl_setopt($oCurl, CURLOPT_PROXYPORT, "10809");
    $sContent = curl_exec($oCurl);
    $aStatus = curl_getinfo($oCurl);
    curl_close($oCurl);
    if (intval($aStatus["http_code"]) == 200) {
        return $sContent;
    } else {
        return false;
    }
}

    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE);

    curl_setopt($curl, CURLOPT_TIMEOUT, 30);
    curl_setopt($curl, CURLOPT_HEADER, 0);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);

    $tmpInfo = curl_exec($curl);
    if (curl_errno($curl)) {
        echo 'Errno' . curl_error($curl);
    }
    curl_close($curl);
    return $tmpInfo;
}
