一般来说，关键字是在 MySQL 字段中搜索的，例如；

[tbl_hp] 标识，标题

1, Harry Potter and the Philosopher's Stone
2, Harry Potter and the Chamber of Secrets
3, Harry Potter and the Prisoner of Azkaban
4, Harry Potter and the Goblet of Fire
5, Harry Potter and the Order of the Phoenix
6, Harry Potter and the Half-Blood Prince
7, Harry Potter and the Deathly Hallows

PHP

$keyword = "Philosopher";
$keyword = "Harry Potter";

SQL

SELECT `id` FROM `tbl_hp` WHERE `title` LIKE '%" . $keyword . "%';

然后结果是；

"Philosopher" => 1
"Harry Potter" => 1,2,3,4,5,6,7

但是如何做到这一点？

[tbl_hp_keywords] id，关键字

1, philosopher
2, chamber
3, azkaban
4, goblet
5, phoenix
6, prince
7, hallows
8, prisoner
9, Prisoner of Azkaban
10, Half-Blood Prince

PHP

$keyword = "Harry Potter and the Chamber of Secrets";
$keyword = "Harry Potter and the Prisoner of Azkaban";
$keyword = "Harry Potter and the Half-Blood Prince";

然后结果是；

"Harry Potter and the Chamber of Secrets" => 2
"Harry Potter and the Prisoner of Azkaban" => 3,8,9 => or even better result is 9
"Harry Potter and the Half-Blood Prince" => 6,10 => or even better resurt is 10

关于如何做到这一点的任何帮助或想法......在此先感谢:)

<?php
$keywords = explode(' ', $keyword);
foreach($keywords AS $key){
    $sql = "SELECT id FROM tbl_hp_keywords WHERE keyword = '$key'";
    $query = mysql_query($sql);
    while($result = mysql_fetch_array($query)){
        $ids[] =$result['id'];
    }
}
$answer[$keyword] = implode(',', $ids);

或者试试这个

$keyword = 'Harry Potter and the Chamber of Secrets';
$keywords = explode(' ', $keyword);
$modifiedKeyword = implode("', '", $keywords);
$sql = "SELECT id FROM tbl_hp_keywords WHERE keyword IN ('$modifiedKeyword')";
try {
    $hostname = 'servername';
    $dbname = 'dbname';
    $username = 'username';
    $pw = "password";
    $pdo = new PDO("mssql:host=$hostname;dbname=$dbname", $username, $pw);
} catch (PDOException $e) {
    echo "Failed to get DB handle: " . $e->getMessage() . "\n";
    exit;
}
$query = $pdo->prepare($sql);
$query->execute();

for ($i = 0; $row = $query->fetch(); $i++) {
    $ids[] = $row['id'];
}

unset($pdo);
unset($query);
