全局变量适用于高并发抢购、秒杀,红包生成,数组算法处理等,由于添加了二维码生成功能,安装本扩展之前需要安装libqrencode,
安装方法如下:(兼容php7)
wget http://fukuchi.org/works/qrencode/qrencode-3.4.4.tar.gz
tar zxvf qrencode-3.4.4.tar.gz
cd qrencode-3.4.4/
./configure
make&make install
如果没有安装libpng和libgd,也需要安装
安装方法如下:
sudo apt-get install libpng-dev
sudo apt-get install libgd-dev
致力于做工具类,其他的正在开发中
===================================
$obj=new zqf();
第一个参数是红包总额,第二个人参数红包数量,第三个参数默认代表拼手气红包,设置为1的话为普通红包
拼手气红包
$hongb= $obj->hongbao(10,8);或者$hongb= $obj->hongbao(10,8,0);返回数组为Array ( [0] => 1.33 [1] => 1.02 [2] => 1.28 [3] => 0.44 [4] => 1.37 [5] => 0.81 [6] => 1.81 [7] => 1.94 )
普通红包,每个人数额一样设置第三个参数
$hongb= $obj->hongbao(10,8,1);返回数组为Array ( [0] => 1.25 [1] => 1.25 [2] => 1.25 [3] => 1.25 [4] => 1.25 [5] => 1.25 [6] => 1.25 [7] => 1.25 )
var_dump($hongb);
首先安装php扩展zqf.so
phpize来安装
然后在php文件调用
dl('zqf.so');或者phpini里加载
$obj=new zqf();
$counter= $obj->autoadd(0,1,0);(声明只针对多线程)
echo $counter;
$asd=array(23,1,21,4,19,89,200,1,78,3,4,7,1,0,88);
$obj=new zqf();
$quick= $obj->quicksort($asd);
print_r($quick);Array ( [0] => 0 [1] => 1 [2] => 1 [3] => 1 [4] => 3 [5] => 4 [6] => 4 [7] => 7 [8] => 19 [9] => 21 [10] => 23 [11] => 78 [12] => 88 [13] => 89 [14] => 200 )
$arr=array(10,20,4,12,69,1,90,56,23,12,89,78);
$obj=new zqf();
$result= $obj->findrepetition($arr);查找$arr重复项算法
var_dump($result);//结果是Array ( [3] => 12 [9] => 12 )
$arr=array(10,20,4,12,69,1,90,56,23,12,89,78);
$obj=new zqf();
$result= $obj->findval($arr,69);二分法快速查找$arr里的元素69,c底层会给数据进行排序
var_dump($result);//结果是Array ( [8] => 69 [result] => Array ( [0] => 1 [1] => 4 [2] => 10 [3] => 12 [4] => 12 [5] => 20 [6] => 23 [7] => 56 [8] => 69 [9] => 78 [10] => 89 [11] => 90 ) )
$obj=new zqf();
$obj->savefile('https://www.baidu.com/s?wd=昌平香堂','./test.png',500);第一个参数是url,第二参数是保存路径,第三个参数是二维码长或者宽
生成透明二维码:
$obj->savefile('https://www.baidu.com/s?wd=昌平香堂','./test.png',500,1);第四个参数默认不生成透明,要想生成透明得传一个参数
