Php 文件有时会导致 500 内部服务器错误

所以，在我们公司我们有分支机构。每个分支机构都被赋予了一组必须每天/每周/每月完成的任务。

我编写了一个脚本，总结了当月每个分支已完成的任务。现在，这可能需要很长时间，具体取决于数据量。（通常随着月份的推移而增加）

月初，一切都运转良好。接近月中/月底时，问题开始发生（通常是因为有更多的数据需要检查，因为有更多的天数）。

这是调用函数来总结所有内容的代码（也是引发 500 错误的页面）：

<?php
ini_set('max_execution_time', 3600);
require_once('../../Connections/newConn.php');
require_once('../../Library/new/branchTaskSummary.php');
header('Content-Type: application/json');
$summary = array();
if(isset($_GET['month']) && isset($_GET['year']) && isset($_GET['update'])) {
    global $conn;
    $update = $_GET['update'] == 1;
    $month = $_GET['month'];
    $year = $_GET['year'];
    if(!$update) {
        $query = $conn->prepare("SELECT data_json, DATE_FORMAT(last_updated, '%d/%m/%Y %H:%i') AS last_updated FROM branchtasksummarydata WHERE month = ? AND year = ?");
        $query->bind_param('ii', $month, $year);
        $query->execute();
        $result = $query->get_result();
        if($result->num_rows > 0) {
            $summary = $result->fetch_assoc();
        } else {
            $summary = summariseEverything($month, $year);
        }
    } else {
        $summary = summariseEverything($month, $year);
    }
}
echo json_encode($summary);
?>

它调用一个名为的函数summarizeEverything，这是所有魔法发生的地方。

这是该函数的代码：

function summariseEverything($month, $year) {
    global $conn;
    $now = new DateTime();
    $data = array();
    $daysInMonth = cal_days_in_month(CAL_GREGORIAN, $month, $year);

现在，当我调用此函数时，它会挂起大约 6/7 分钟，然后才会出现内部服务器错误。

有趣的是，我在本地机器上测试它并且运行良好。但是，在实时服务器上，它会抛出错误。

编辑

回来尝试解决这个问题后，我打开了我可以打开的所有错误日志记录，它只是在每次循环分支迭代时给我这些：

Notice: Undefined index: total in C:\WS\JMIS\Library\new\branchTaskSummary.php on line 61

如果没有日志记录，它会抛出 500 内部服务器错误。我一生都无法弄清楚发生了什么事！该代码有效，我已经在多个本地系统上对其进行了测试。但似乎无法在我无权访问的实时服务器上工作。

使用

ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
