Question

我想计算文件中的所有双重事件。例如：

$outputArr = array();
foreach($numArr as $k1 => $val){
    foreach($val as $k2 => $val2){
        $outputArr[$k2] = $numArr[$k1][$k2];
    }

    $Opos0 = serialize($connect->real_escape_string(var_export($outputArr[0])));
    $Opos1 = serialize((int)var_export($outputArr[1]));
    $Opos2 = serialize((int)var_export($outputArr[2]));
    $Opos3 = serialize((int)var_export($outputArr[3]));
    $Opos4 = serialize((int)var_export($outputArr[4]));
    $Opos5 = serialize((int)var_export($outputArr[5]));
    $Opos6 = serialize((int)var_export($outputArr[6]));
    $Opos7 = serialize((int)var_export($outputArr[7]));
    $Opos8 = serialize((float)var_export($outputArr[8]));
    $Opos9 = serialize((float)var_export($outputArr[9]));
    $Opos10 = serialize((float)var_export($outputArr[10]));
    $Opos11 = serialize((float)var_export($outputArr[11]));
    $Opos12 = serialize((float)var_export($outputArr[12]));
    $Opos13 = serialize($connect->real_escape_string(var_export($outputArr[13])));

    $query = "INSERT INTO `num_data`(`CalledNum`, `NumCalls`, `uniqueCalls`, `dur1sec`, `dur30sec`, `dur60sec`, `dur90sec`, `dur120sec`, 
    `grossIncome`, `cogs`, `split`, `netIncome`, `nipuc`, `CallDate`) VALUES ($Opos0, $Opos1, $Opos2, $Opos3, $Opos4, $Opos5, $Opos6, 
    $Opos7, $Opos8, $Opos9, $Opos10, $Opos11, $Opos12, $Opos13)";
    $result = $connect->query($query);
    if($result == false){
        echo "<p>Error entering data into num_data!</p>";
        echo "<pre>", print_r( $query ), "</pre>";
        die(mysqli_error($connect));
    }
    $k2 = 0;
}   //Parse numArr info into INSERT command.`

我试过这段代码：

hellohello (this is counted)
hello (not conted)

但它不起作用，我不明白为什么。

请参阅http://mywiki.wooledge.org/ParsingLs了解for file in $(find ...)为何错误的原因。

关于主要问题虽然认识到{2,2}（以及所有其他修饰符）适用于模式中最近的原子，并且字符本身就是一个原子所以你所写的是

h + e + l + l + o{2,2}

这不是你想要的。

您希望hello成为原子，因此群组为：(hello){2,2}。
