Question

我将一个csv文件上传到服务器。该文件正在读取数据并保存到数据库中但是，我的服务器的问题是最大执行时间是180秒。我无法在180秒内将所有数据上传到csv中。服务器显示为＆＃34; 服务不可用＆＃34; 180秒后所以我决定在后台完成 csv上传。我尝试了很少的插件，但我收到的错误就像没有找到插件和其他一些插件。我需要 cakephp中的解决方案。提前致谢

Answer 1

我怀疑上传本身需要180秒。您应该重新考虑您的设计并首先收集数据，然后将其写入数据库，如果在cakephp中可用，可以使用批量插入。

Answer 2

您可以像这样延长执行时间。

ini_set('max_execution_time', 600); //600 seconds = 10 minutes

将其放在CSV上传脚本的顶部。您可以根据需要更改第二个参数。

Answer 3

第1步 - 数据库连接

首先我们需要连接数据库... 文件名：connection.php

<?php
$db = mysql_connect("Database", "username", "password") or die("Could not connect.");

if(!$db) 

    die("no db");

if(!mysql_select_db("Databasename",$db))

    die("No database selected.");
?>

第2步 - 上传页面

通过调用connection.php建立与数据库的连接，清理旧数据表，将新上传的数据插入表中... 文件名：upload.php
