PHP实现动态柱状图改进版，php柱状图改进版
本文实例分析了PHP实现动态柱状图的改进版。分享给大家供大家参考。具体分析如下：
前面已经写过如果只做动态柱状图的情况，其实原理还是很简单的。因为昨天下午有新的需求，今天上午又修改了一番，并将数据根据编号不同分割显示在表中。
下面把代码粘出来，方便以后自己查看，思路只是一时的火花，今天我想出来这么做，不一定下次还能想得到，也不用费劲的去想，所以写成笔记是比较好的形式。

<?php
// 计算上一个月的今天

{
$last_month_time = mktime(date("G", $time), date("i", $time), date("s", $time), date("n", $time), 0, date("Y", $time));
$last_month_t = date("t", $last_month_time);
if ($last_month_t < date("j", $time)) {
return date("Y-m-t H:i:s", $last_month_time);
}
return date(date("Y-m", $last_month_time) . "-d", $time);
}
?>
<?php
include dirname(dirname(dirname(__FILE__))) . '/config.php';
$endDate = date('Y-m-d');

<!-- 因为总的列数比较长，如果显示在一个表格中，数据会很拥挤，多的话根本就看不清楚。

</html>数据库方便就不弄了，其实，根据查询的表名和字段名，是很容易建一个测试的数据表的。关键是思路，无论怎么变，思路是关键。

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
Apr 05, 2025 am 12:04 AM
JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Explain late static binding in PHP (static::).
Apr 03, 2025 am 12:04 AM
Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
