How can I use multiple keywords with REGEXP?

Question

I have a query like so

SELECT name FROM users WHERE interests REGEXP :interests

since interests are varied, I have an array of submitted interests that I'm imploding to reach the database like golf|soccer|tennis . I'm then using that array to replace :interests but MYSQL is throwing an error:

SQLSTATE[HY000]: General error: property queryString is read only

Idealy the query should read:

SELECT name FROM users WHERE interests REGEXP golf|tennis|chess

I'm using PDO, what's the workaround I can use?

EDIT: This is the other php code, as requested

$keys = implode('|', array_filter($f3->get('keywords')));

//query the database, looking for matches in the users table.
$q = $db->prepare("SELECT * FROM users WHERE interests REGEXP :keywords");
$q->execute(array(':keywords' => $keys));
$q->setFetchMode(PDO::FETCH_ASSOC);
$q->fetchAll();

Answer 1

$result = $q->fetchAll();

我回溯了我的步骤，并将结果分配给一个变量，一切正常！
