While Loop using PHP with a MySQL server

问题

I have a database (SQL) with the table "Staff" with two records in it. I am required to display the contents of these records on a web page using PHP.

<html>
<head>
<title>CES Staff details</title>
</head>

<body>

**code emitted**

<?php
$row = mysql_fetch_array($result) ; 
$looping = 1;
$i = $row.length;
while ($looping <= $i)  
    {
        echo $row["Name"].", Room ".$row["Room"].", Tel ".$row["Telephone"] ;
        $looping++;
    }
?>
</body>
</html>

How would I change the while loop correctly so that it will display both records on the page.

Thanks!

回答1:

mysql_fetch_array() only retrieves a single row from the database. You need to call it inside your while loop to retrieve all rows. The $looping increment is unnecessary here, since mysql_fetch_array() returns false when no more rows are available.

while ($row = mysql_fetch_array($result))  
{
    echo $row["Name"].", Room ".$row["Room"].", Tel ".$row["Telephone"] ;
}

I'll do...

while ($row = mysql_fetch_assoc($result)) {
   // print $row;
}

回答3:

while ($row = mysql_fetch_array($result))  
    {
        echo $row["Name"].", Room ".$row["Room"].", Tel ".$row["Telephone"] ;
    }

回答4:

<?php
$qry = mysql_query($result); 
while ($row = mysql_fetch_array($qry))  
    {
        echo $row["Name"].", Room ".$row["Room"].", Tel ".$row["Telephone"] ;
    }
?>

PHP has great documentation with examples. Check out the example for mysql_fetch_array().

Your code should look like this:

<?php
  while($row = mysql_fetch_array($result)) {
     echo $row["Name"].", Room ".$row["Room"].", Tel ".$row["Telephone"] ;
  }
?>

Use this

while($row = mysql_fetch_array($result)) 
{
   echo $row["Name"].", Room ".$row["Room"].", Tel ".$row["Telephone"] ; 
}

In php there is no such thing like $row.length; the "." is an operator for string concatenation. Read more on mysql_fetch_array at http://php.net/manual/en/function.mysql-fetch-array.php.

<?php
  while($row = mysqli_fetch_array($result,MYSQLI_ASSOC)) {
     echo $row["Name"].", Room ".$row["Room"].", Tel ".$row["Telephone"] ;
  }
?>
