PHP实践—随机彩票代码

<?php
    $arr = array();
    $special = array();
    //1-32位号码
    for ($i = 1; $i <= 32 ; $i++){
        $arr[$i] = $i;
    }
    //1-15特别号码
    for ($i = 1; $i <= 15 ; $i++) { 
        $special[$i] = $i;
    }
    //随机取数组
    $arr2 = array_rand($arr,6);
    $arr3 = array_rand($special,1);

    $arr2[] = $arr3;

    $str = "<div style='font-size:16px;padding-top:10px;text-align:center'>";
    foreach($arr2 as $v){
        $str .= "<span style='color:red;font-size:25px'>$v---</span>";
    }
    $str .='</div>';

    echo $str;
