顯示數據庫中的表時出錯

Question

我正在嘗試使用PHP顯示我的表，t2d_10和數據庫chr10。我的表有5列，分別是rs1，rs2，rs3，rs4，rs5。這是我的代碼：

<?php 

// set database server access variables: 
$host = "localhost"; 
$user = "root"; 
$pass = ""; 
$db = "chr10"; 

// open connection 
$connection = mysql_connect($host, $user, $pass) or die ("Unable to connect!"); 

// select database 
mysql_select_db($db, $connection) or die ("Unable to select database!"); 

// create query 
$query = "SELECT * FROM t2d_10"; 

// execute query 
$result = mysql_query($query) or die ("Error in query: $query. ".mysql_error()); 

// see if any rows were returned 
if (mysql_num_rows($result) > 0) { 
    // yes 
    // print them one after another 
    echo "<table cellpadding=10 border=1>"; 
    while($row = mysql_fetch_row($result)) { 
     echo "<tr>"; 
     echo "<td>".$row['rs1']."</td>"; 
     echo "<td>".$row['rs2']."</td>"; 
     echo "<td>".$row['rs3']."</td>"; 
     echo "<td>".$row['rs4']."</td>"; 
     echo "<td>".$row['rs5']."</td>"; 
     echo "</tr>"; 
    } 
    echo "</table>"; 
} 
else { 
    // no 
    // print status message 
    echo "No rows found!"; 
} 

// free result set memory 
mysql_free_result($result); 

// close connection 
mysql_close($connection); 

?> 

錯誤：

Notice: Undefined index: rs1 in C:\wamp\www\ch\run_db.php on line 28 

Notice: Undefined index: rs2 in C:\wamp\www\ch\run_db.php on line 29 

Notice: Undefined index: rs3 in C:\wamp\www\ch\run_db.php on line 30 

Notice: Undefined index: rs4 in C:\wamp\www\ch\run_db.php on line 31 

Notice: Undefined index: rs5 in C:\wamp\www\ch\run_db.php on line 32 

我是相當新的這個PHP。任何人都可以幫助我嗎？提前致謝。

Answer 1

mysql_fetch_row()只是一個索引數組。

要麼使用mysql_fetch_array()或mysql_fetch_assoc()

檢查：Difference between mysql_fetch_array and mysql_fetch_row?

語法高亮顯示和錯誤消息都告訴你到底發生了什麼問題。

您錯過了代碼中的一些"字符。
