大家知道,數(shù)據(jù)庫對(duì)于網(wǎng)絡(luò)來說的重要性.由于cgi的復(fù)雜,現(xiàn)在asp和php+mysql已經(jīng)成為主流.幾乎所有的個(gè)人網(wǎng)頁都要用到留言本,可是申請(qǐng)的留言本很不穩(wěn)定.這為網(wǎng)上的交流帶來了諸多不便.所以,希望擁有自己的留言本的朋友越來越多.
但是,免費(fèi)的個(gè)人主頁支持asp和php的很少.筆者現(xiàn)在向您推薦奧索網(wǎng),(http://www.oso.com.cn)支持php.這樣您便有了能夠擁有自己留言本的基礎(chǔ).現(xiàn)在,我就通過一個(gè)文本留言本的例子來講述php的簡單使用.
首先,我們先確定,留言的幾個(gè)過程:寫留言,發(fā)送,查看.(搜索)等等.而且對(duì)于斑竹來說,管理留言本又是不可或缺的.這樣我們就不妨定位于6個(gè)php文件,1個(gè)文本文件.6個(gè)php文件分別為:guest.php manage.php reply.php sys.php del.php edit.php,1個(gè)文本文件為:guest.txt
先來看看guest.php的內(nèi)容,你當(dāng)然可以直接將下面的內(nèi)容放到您的php網(wǎng)頁里,請(qǐng)尊重作者的勞動(dòng),謝謝.
