php - 如何从 MySQL 'LIKE' 接收各种结果？

Question

所以，我编写了这段代码，并且它有效。但是，它只返回一个结果。所以我的数据库中有 2 个“Eric Clapton”名字，每个名字都有不同的 id。但查询只返回这 2 个中的一个。有什么想法吗？

<?php

$now = htmlentities(rawurldecode($_GET['word'])); // in this case i passed in 'Eric Clapton'
$cat = htmlentities($_GET['cat']); // category, in this case lets say i passed in 'music'

$con = mysql_connect("localhost","USERNAME","PASS");
if (!$con)
  {
  echo "<pre>An error occured, please try again later. Sorry...</pre>"; 
  }
else{ mysql_select_db("DATABASE", $con);

    $result = mysql_query("SELECT id, name FROM $cat WHERE name LIKE '%$now%'");
    $row = mysql_fetch_array($result);

    echo "<pre>";
    print_r($row);
    echo "</pre>";

mysql_close($con);  
}
?>

说实话，现在我们正在谈论->

<?php

$now = '%'.htmlentities(rawurldecode($_GET['word'])).'%';
$cat = htmlentities($_GET['cat']); 

$dsn = 'mysql:dbname=DATABASE;host=localhost';
$user = "USER";
$password = "PASS";

# connect to the database
try {
    $DBH = new PDO($dsn, $user, $password);
    $DBH->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );

    # the data we want to insert
    $data = array($now);

    $STH = $DBH->prepare("SELECT id, name FROM $cat WHERE name LIKE ?");
    $STH->execute($data);
    $result = $STH->fetchAll();

}
catch(PDOException $e) {
    echo "Uh-Oh, something wen't wrong. Please try again later.";
    file_put_contents('PDOErrors.txt', $e->getMessage(), FILE_APPEND);
}

echo "<pre>";
print_r($result);
echo "</pre>";

$DBH = null;

?>

您缺少循环，即循环显示结果的位置:

while($row = mysql_fetch_array($result))
{
    echo "<pre>";
    print_r($row);
    echo "</pre>";
}

您当前所做的是从结果中获取第一行。
