本文實例講述了PHP實現(xiàn)簡單的新聞發(fā)布系統(tǒng)。分享給大家供大家參考。具體如下：
本人小白，一直在公司用模板和框架寫PHP，發(fā)現(xiàn)有時候連基本的sql語句都忘記了，所以有空想把PHP基礎(chǔ)復(fù)習(xí)下，鞏固下。分頁和搜索，以及排序，還沒寫，后期繼續(xù)更新...（代碼修改：添加搜索和分頁功能）

基礎(chǔ)知識總結(jié)：
文章發(fā)布系統(tǒng)
1.articlePublish.html 發(fā)布文章頁面 提交到articlePublishDo.php頁面,執(zhí)行寫入數(shù)據(jù)庫
2.articleList.php 文章列表頁面
3.點擊編輯,修改文章 提交到 aiticleEdit.php 表單頁面（回顯）
4.點擊修改文章按鈕 提交到 articleUpdate.php
希望本文所述對大家的php程序設(shè)計有所幫助。
