假设您想在浏览器中显示它并从 MySQL 获取数据。使用此代码，将您的dbnameand替换tablename为正确的值：

<html>
<head><title>Result as Table</title></head>
<body>
<?php
$db_host = 'localhost';
$db_user = 'root';
$db_pwd = '';

$database = 'dbname';
$table = 'tablename';

if (!mysql_connect($db_host, $db_user, $db_pwd))
    die("Can't connect to database");

if (!mysql_select_db($database))
    die("Can't select database");

// sending query
$result = mysql_query("SELECT * FROM {$table}");
if (!$result) {
    die("Query to show fields from table failed");
}

$fields_num = mysql_num_fields($result);

echo "<h1>Table: {$table}</h1>";
echo "<table border='1'><tr>";
// printing table headers
for($i=0; $i<$fields_num; $i++)
{
    $field = mysql_fetch_field($result);
    echo "<td>{$field->name}</td>";
}
echo "</tr>\n";
// printing table rows
while($row = mysql_fetch_row($result))
{
    echo "<tr>";

    // $row is array... foreach( .. ) puts every element
    // of $row to $cell variable
    foreach($row as $cell)
        echo "<td>$cell</td>";

    echo "</tr>\n";
}
mysql_free_result($result);
?>
</body></html>

查看printf/sprintf：

printf('| %3s | %-5.1f | …', $rate, $conns, …);

printf() 是你的朋友。

<?php
function printRows($rows){
    $br = "+----------------------------------------------------------------+";
    $he = "| rate | conn/s | req/s | replies/s avg | errors | net io (KB/s) |";

    //Print out the header
    print "$br\n$he\n$br\n";

    //Iterate through the rows
    foreach($rows as $row){
        printf("|[%-5s] | [%-7s] | [%-5s] | [%-13s] | [%-6s] | [%-13s] |",
               $row[0],$row[1],$row[2],$row[3],$row[4],$row[5] 
              );

    }

    //Print the end ascii-art
    print "$br\n";
}
?>
