php如何拼接表單數(shù)據(jù) php 拼接

php 如何把兩段數(shù)據(jù)庫(kù)內(nèi)容拼接？

程序開(kāi)始建立兩個(gè)數(shù)據(jù)庫(kù)連接，函數(shù)mysql_query()原型：

員工經(jīng)過(guò)長(zhǎng)期磨合與沉淀，具備了協(xié)作精神，得以通過(guò)團(tuán)隊(duì)的力量開(kāi)發(fā)出優(yōu)質(zhì)的產(chǎn)品。創(chuàng)新互聯(lián)建站堅(jiān)持“專(zhuān)注、創(chuàng)新、易用”的產(chǎn)品理念，因?yàn)椤皩?zhuān)注所以專(zhuān)業(yè)、創(chuàng)新互聯(lián)網(wǎng)站所以易用所以簡(jiǎn)單”。公司專(zhuān)注于為企業(yè)提供成都網(wǎng)站設(shè)計(jì)、成都做網(wǎng)站、微信公眾號(hào)開(kāi)發(fā)、電商網(wǎng)站開(kāi)發(fā)，微信平臺(tái)小程序開(kāi)發(fā)，軟件定制開(kāi)發(fā)等一站式互聯(lián)網(wǎng)企業(yè)服務(wù)。

resource?mysql_query?(?string?$query?[,?resource?$link_identifier?] )

方法1：在mysql_query函數(shù)中指定所用連接，即：

方法2：在sql語(yǔ)句中關(guān)聯(lián)所用數(shù)據(jù)庫(kù)，此時(shí)可以省略mysql_query的第二個(gè)參數(shù)，即：

首先直接做成一頁(yè)，中間步驟的數(shù)據(jù)處理用JS，然后就可以正常提交，交給原系統(tǒng)的注冊(cè)處理頁(yè)面

PHP連接到數(shù)據(jù)庫(kù)表單代碼

mysql_connect("localhost","username","password");

PDO方式,比較通用

new PDO('mysql:host=localhost;dbname=db',"$username","password");

mysqli方式

new mysqli("localhost", "username", "password", "db");

odbc方式

odbc_connect("'DRIVER={SQL Server};SERVER=local;DATABASE=db", $username, $password)

new COM("ADODB.Connection");
