帮助PHP搜索

Question

如果找不到任何行，我该如何让用户知道？ 如果它找到（例如）26行我希望它打印它发现26次点击（你搜索“嘿”给出了26个结果）

$name = mysql_real_escape_string($_POST['player_name']);

$q = mysql_query("SELECT * FROM players WHERE name LIKE '%$name%'");

while ($row = mysql_fetch_array($q)) { 

$name  = $row['name']; 

    echo "<ul>\n"; 
    echo "<li>" . "<a  href=\"player-info.php?id=\">"   .$name . " </a></li>\n"; 
    echo "</ul>"; 
}

Answer 1

使用mysql_num_rows：

$rowCount = mysql_num_rows($q);
if ($rowCount === 0)
{
    echo 'Found nothing!';
}
else
{
    echo "Found $rowCount rows!";
    while ($row = mysql_fetch_array($q))
    { 
        $name  = $row['name'];
        echo "<ul>\n"; 
        echo "<li>" . "<a  href=\"player-info.php?id=\">"   .$name . " </a></li>\n"; 
        echo "</ul>"; 
    }
}
