下面小編就為大家?guī)硪黄狿HP MySql增刪改查的簡單實(shí)例。小編覺得挺不錯(cuò)的，現(xiàn)在就分享給大家，也給大家做個(gè)參考。

mysql_connect()連接數(shù)據(jù)庫

mysql_select_db選擇數(shù)據(jù)庫

mysql_fetch_assoc()獲取結(jié)果集

mysql_query()執(zhí)行sql語句

實(shí)例如下：

<?php

  $con=@mysql_connect('localhost','root','root');//連接數(shù)據(jù)庫

  mysql_select_db('test',$con);//選擇數(shù)據(jù)庫

  $userInfo=mysql_query("select * from user",$con);//創(chuàng)建sql語句

  echo "<table>";

  while($row=mysql_fetch_assoc($userInfo))//獲取結(jié)果集每一行的數(shù)據(jù)

  {

    echo "<tr>";

    echo "<td>";

    echo $row['id'];//獲取行中的id

    echo "</td>";

    echo "<td>";

    echo $row['username'];

    echo "</td>";

    echo "<td>";

    echo $row['password'];

    echo "</td>";

    echo "</tr>";

  }

  echo "</table>";

  mysql_free_result($userInfo);//釋放結(jié)果集

  mysql_close($con); //關(guān)閉數(shù)據(jù)庫

  /*delete

  $d=@mysql_connect('localhost','root','root');

  mysql_select_db('test',$d);

  mysql_query("delete from user where id=1",$d);

  mysql_close($d);

  */

  /*insert

  $i=@mysql_connect('localhost','root','root');

  mysql_select_db('test',$i);

  mysql_query("insert into user(username,password) values('ad','ad')",$i);

  mysql_close($i);

  */

  //update

  $u=@mysql_connect('localhost','root','root');

  mysql_select_db('test',$u);

  mysql_query("update user set username='aaa' where username='00'",$u);

  echo "update user set username='ax' where id=2";

  mysql_close($u);

?>

以上這篇PHP MySql增刪改查的簡單實(shí)例就是小編分享給大家的全部內(nèi)容了，希望能給大家一個(gè)參考
