php - 遍历行、更新并发送电子邮件

Question

我在遍历行、更新字段、然后根据日期发送电子邮件时遇到问题。我也可以让第一行发送电子邮件，但我不明白为什么我无法让其他行发送电子邮件。我可以显示返回了三行，但我无法发送三封电子邮件。代码如下，提前感谢您的帮助。

<?php




    for($numOfRows = 1; $numOfRows > 0;){       

    $sql = "SELECT * FROM service WHERE boosterDate BETWEEN CURDATE() AND CURDATE() + INTERVAL 30 DAY";

if(!$result = $con->query($sql)){
    die('There was an error running the query [' . $con->error . ']');  
    }

    $numOfRows = $result->num_rows;
    //%result->store_result();
    $numOfRows = var_dump($numOfRows);
    //echo $numOfRows;

//if($numOfRows > 0){

    //var_dump($numOfRows);

while($row = $result->fetch_array()){
        //Get all the rows and store them in an array   
    $firstQueryRows[] = $row;

}

foreach($firstQueryRows as $row){

您没有通过 for 循环进行迭代，并且您的代码有点困惑 :p 。您想发送三封电子邮件，请尝试以下操作:

for($numOfRows = 0; $numOfRows <= 3; $numOfRows++)
