"你是獵人還是獵物？"

淺談php mysql與mysqli連結資料庫及查詢資料表及內文列印的不同語法

mysql資料庫連結語法
<?php
$dbhost="localhost";
$dbuser="root";
$dbpass="";


$dberror1="Could Not Connect to Your Database";
$dberror2="Could Not Find Your Table";

mysql_pconnect($dbhost,$dbuser,$dbpass) or die ($dberror1);
$select_db=mysql_select_db('資料庫名稱') or die($dberror2);
mysql_query("SET NAMES UTF8");
if(isset($_POST['uCheck']) and isset($_POST['pCheck'])) {
if(isset($_POST['remember'])) {
//設定一名稱為rmUsername的cookie，記錄輸入的使用者帳號，保存期限30天
setcookie("rmUsername",$_POST['uCheck'],time()+3600*24*30);
//設定一名稱為rmPassword的cookie，記錄輸入的使用者密碼，保存期限30天
setcookie("rmPassword",$_POST['pCheck'],time()+3600*24*30);
}else{
setcookie("rmUsername",'', time()); //刪除記錄帳號的Cookie
setcookie("rmPassword",'', time()); //刪除記錄密碼的Cookie
}
}
?>

mysqli資料庫連結語法
<?php
$dbhost="localhost";
$dbuser="root";
$dbpass="";
$dberror1="Could Not Connect to Your Database";
$dberror2="Could Not Find Your Table";
$Conn=mysqli_connect($dbhost,$dbuser,$dbpass) or die ($dberror1);
$select_db=mysqli_select_db($Conn,'資料庫名稱') or die($dberror2);
mysqli_query($Conn,'set names utf8');
if(isset($_POST['uCheck']) and isset($_POST['pCheck'])) {
if(isset($_POST['remember'])) {
//設定一名稱為rmUsername的cookie，記錄輸入的使用者帳號，保存期限30天
setcookie("rmUsername",$_POST['uCheck'],time()+3600*24*30);
//設定一名稱為rmPassword的cookie，記錄輸入的使用者密碼，保存期限30天
setcookie("rmPassword",$_POST['pCheck'],time()+3600*24*30);
}else{
setcookie("rmUsername",'', time()); //刪除記錄帳號的Cookie
setcookie("rmPassword",'', time()); //刪除記錄密碼的Cookie
}
}
?>


mysql資料表查詢及內文列印語法
<?php
$row_web_shop=mysql_query("Select * FROM shop2pic");//資料表查詢
$web_shop= mysql_num_rows($row_web_shop);//函数返回结果集中行的数目
?>

<?php do { ?>
<?php  if ($web_shop ['shop2pic_pic'] !== NULL){ ?>
    <div style="margin-left:10px;width:650px;">
    <li  style="list-style-type:none;word-break:break-all;font-size:14px;margin-top:0px; border-bottom:#B3D983 0px solid ;margin-right:20px;float:left;height:150px;"  >
<img style="border:0px blue solid;width:120px;" src="images/shop/<?php echo $web_shop['shop2pic_pic']; ?>" title="<?php echo $web_shop['p_color']; ?>"/>
    <p style="border:0px red solid;margin-top:10px;height:20px;width:100px;overflow:hidden;text-align:center"> <b><?php  echo mb_substr(strip_tags( $web_shop['p_color']),0,20,"UTF-8");?></b> <!--echo列印陣列行數的數目-->    
      </p>
     </li>
</div>
    <?php } // Show if recordset not empty ?>
   <?php } while ($web_shop = mysql_fetch_assoc($row_web_shop)); ?>      

mysqli資料表查詢及內文列印語法
<?php
$row_web_shop=mysqli_query($conn_web,"Select * FROM shop2pic");//資料表查詢
$web_shop= mysqli_num_rows($row_web_shop);//函数返回结果集中行的数目
?>

<?php do { ?>

<?php  if ($web_shop ['shop2pic_pic'] !== NULL){ ?>
 
    <li  style="list-style-type:none;word-break:break-all;font-size:14px;margin-top:0px; border-bottom:#B3D983 0px solid ;margin-left:10px;float:left;"  >
<img style="border:0px blue solid;height:100px;width:100px;" src="images/shop/<?php echo $web_shop['shop2pic_pic']; ?>" title="<?php echo $web_shop['p_color']; ?>"/>
    <p style="border:0px red solid;margin-top:10px;height:20px;width:100px;overflow:hidden;text-align:center"> <b><?php  echo mb_substr(strip_tags( $web_shop['p_color']),0,20,"UTF-8");?></b> <!--echo列印陣列行數的數目-->    
      </p>
     </li>            
    <?php } // Show if recordset not empty ?>  
   <?php } while ($web_shop = mysqli_fetch_assoc($row_web_shop)); ?>
