項(xiàng)目進(jìn)度管理系統(tǒng)是一種用于跟蹤和管理項(xiàng)目進(jìn)度的工具，能夠幫助團(tuán)隊(duì)更好地規(guī)劃項(xiàng)目，并確保項(xiàng)目按時(shí)完成。隨著現(xiàn)代軟件開(kāi)發(fā)行業(yè)的快速發(fā)展，項(xiàng)目進(jìn)度管理系統(tǒng)已經(jīng)成為了許多團(tuán)隊(duì)中必不可少的工具。本文將介紹如何使用 PHP 編寫一個(gè)項(xiàng)目進(jìn)度管理系統(tǒng)。

首先，我們需要確定項(xiàng)目進(jìn)度管理系統(tǒng)所需的功能。一個(gè)基本的項(xiàng)目進(jìn)度管理系統(tǒng)應(yīng)該包括以下功能：

1. 項(xiàng)目概述：列出項(xiàng)目的名稱、目的、范圍、負(fù)責(zé)人等信息。
2. 任務(wù)列表：列出項(xiàng)目中的所有任務(wù)，包括任務(wù)名稱、描述、優(yōu)先級(jí)、負(fù)責(zé)人等信息。
3. 任務(wù)狀態(tài)：跟蹤任務(wù)的狀態(tài)，包括已完成、進(jìn)行中、未開(kāi)始等。
4. 任務(wù)進(jìn)度：跟蹤任務(wù)的進(jìn)度，包括任務(wù)完成進(jìn)度、任務(wù)正在進(jìn)行中進(jìn)度、任務(wù)未開(kāi)始進(jìn)度等信息。
5. 任務(wù)提醒：為任務(wù)提供提醒，以便團(tuán)隊(duì)管理員能夠及時(shí)提醒負(fù)責(zé)人完成任務(wù)。
6. 報(bào)告：生成各種報(bào)告，包括項(xiàng)目進(jìn)度報(bào)告、任務(wù)完成報(bào)告、預(yù)算報(bào)告等。

接下來(lái)，我們需要編寫 PHP 代碼來(lái)實(shí)現(xiàn)項(xiàng)目進(jìn)度管理系統(tǒng)所需的功能。以下是一個(gè)簡(jiǎn)單的項(xiàng)目進(jìn)度管理系統(tǒng)的示例代碼：
