PHP随机抓取QQ头像或昵称

通过拼接随机数，以及已知的接口，使用循环抓取数据并保存。

$time_start = time();  // 开始时间

$tongji_file = "./c.php";
$tongji = array();
if(file_exists($tongji_file)){
    $tongji = require($tongji_file);
}

$num = 100;

$json_arr = array();
$data_file = "./data.php";
if(file_exists($data_file)){
    $json_arr = require($data_file);
}

for($j=1; $j<=$num; $j++){

// 生成8-11位随机数
    $rand_str = "";
    $wei = rand(10,11);
    for($i=0;$i<$wei;$i++){
        if($i==0){
            $rand_str .= rand(1,9);
        }else{
            $rand_str .= rand(0,9);
        }
    }
    $rand_url = "https://r.qzone.qq.com/fcg-bin/cgi_get_portrait.fcg?uins=".$rand_str;
//初始化curl对象
    $ch = curl_init();
//设置URL
    curl_setopt($ch, CURLOPT_URL, $rand_url);
// 字符串形式
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// 允许301,302
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
// 取消https验证
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
    curl_setopt($ch,CURLOPT_CONNECTTIMEOUT ,0);  // 无限等待时长

    $result =     curl_exec($ch);
// 字符转码
    $data=iconv("GB2312","UTF-8",$result);

// 去掉port
    $pattern = '/portraitCallBack\((.*)\)/is';
    preg_match($pattern,$data,$result);
    $result=$result[1];

// 字符串转arr
    $arr = json_decode($result,true);

        echo "<p>头像地址：<img src='$img'/></p>";
        echo "<p>昵称：$qq_nick</p>";

        $json_arr[] = [
            'qq' => $qq,
            'name' => $qq_nick,
            'img' => $qq_img
        ];

    }else{

        $j--;
        continue;

}
$time_end = time();

$current = ($time_end-$time_start);
echo "<p>本次用时：".$current."秒</p>";

$totalSum = 0;
foreach ($tongji as $k=>$v){
    $totalSum += $v;
}

$avg = number_format($totalSum/count($tongji,2));

file_put_contents($tongji_file,$text);

// 保存数据
