php怎樣來建立一個(gè)表格呀

1、首先創(chuàng)建一個(gè)html文件,編寫上基本的代碼,在head頭部中引入jquery路徑,用于調(diào)用其中封裝的方法。

2、編寫一個(gè)簡單的表格樣式,并編寫一個(gè)執(zhí)行按鈕,用于id,此時(shí)需要給table賦予一個(gè)id屬性。

3、打開瀏覽器,看一下表格效果,目前是有兩行單元格,有兩列數(shù)據(jù)。

3、編寫js代碼實(shí)現(xiàn)點(diǎn)擊效果,先寫一個(gè)按鈕單擊事件,用click方法實(shí)現(xiàn)。

4、在click()方法中編寫表格增加一行的效果,先編寫一行表格的html代碼,轉(zhuǎn)為字符串,然后用append( )方法將字符串追加到表格當(dāng)中。

5、回到瀏覽器界面,點(diǎn)擊click按鈕,會(huì)發(fā)現(xiàn)自動(dòng)多了一行表格內(nèi)容,點(diǎn)擊按鈕添加一行表格就實(shí)現(xiàn)了。

如何在php創(chuàng)建數(shù)據(jù)庫與數(shù)據(jù)表

創(chuàng)建數(shù)據(jù)庫:create database 數(shù)據(jù)庫名

創(chuàng)建數(shù)據(jù)表:

CREATE TABLE `users` (

`id` tinyint(10) auto_increment primary key NOT NULL,

`username` varchar(30) NOT NULL,

`age` int(10) NOT NULL

) ENGINE=MyISAM DEFAULT CHARSET=utf8;

執(zhí)行這兩個(gè)sql語句就行

什么是PHP?

PHP是超文本預(yù)處理器,是一種通用開源腳本語言。

PHP獨(dú)特的語法混合了C、Java、Perl以及 PHP 自創(chuàng)的語法。利于學(xué)習(xí),使用廣泛,主要適用于Web開發(fā)領(lǐng)域。

優(yōu)點(diǎn):

1、流行,容易上手

PHP是目前最流行的編程語言,這毋庸置疑。它驅(qū)動(dòng)全球超過2億多個(gè)網(wǎng)站,有全球超過81.7%的公共網(wǎng)站在服務(wù)器端采用PHP。PHP常用的數(shù)據(jù)結(jié)構(gòu)都內(nèi)置了,使用起來方便簡單,也一點(diǎn)都不復(fù)雜,表達(dá)能力相當(dāng)靈活。

2、開發(fā)職位很多

在服務(wù)器端的網(wǎng)站編程中PHP會(huì)更容易幫助你找到工作。很多互聯(lián)網(wǎng)相關(guān)企業(yè)都在使用PHP開發(fā)框架,所以可以說市場對(duì)PHP的開發(fā)程序員的需求還是比較大的。

3、仍然在不斷發(fā)展

PHP在不斷兼容著類似closures和命名空間等技術(shù),同時(shí)兼顧性能和當(dāng)下流行的框架。版本是7之后,一直在提供更高性能的應(yīng)用。

4、可植入性強(qiáng)

PHP 語言在補(bǔ)丁漏洞升級(jí)過程中,核心部分植入簡單易行,且速度快。

5、拓展性強(qiáng)

PHP 語言在數(shù)據(jù)庫應(yīng)用過程中,可以從數(shù)據(jù)庫調(diào)取各類數(shù)據(jù),執(zhí)行效率高。

擴(kuò)展資料:

缺點(diǎn)

1、PHP的解釋運(yùn)行機(jī)制

在 PHP 中,所有的變量都是頁面級(jí)的,無論是全局變量, 還是類的靜態(tài)成員,都會(huì)在頁面執(zhí)行完畢后被清空。

2、設(shè)計(jì)缺陷

缺少關(guān)注PHP被稱作是不透明的語言,因?yàn)闆]有堆棧追蹤,各種脆弱的輸入。沒有一個(gè)明確的設(shè)計(jì)哲學(xué)。早期的PHP受到Perl的影響,帶有out參數(shù)的標(biāo)準(zhǔn)庫又是有C語言引入,面向?qū)ο蟮牟糠钟质菑?C++和Java學(xué)來的。

3、對(duì)遞歸的不良支持

PHP并不擅長遞歸。它能容忍的遞歸函數(shù)的數(shù)量限制和其他語言比起來明顯少。
