Can You Bind Array Parameters with LIMIT Clause in PDO?

Passing Array Parameters with LIMIT Clause in PDO

In PHP, the PDOStatement class provides a way to execute SQL queries with parameterized values. However, when using the LIMIT clause, binding parameters using the bindParam() method does not work.

To overcome this issue, consider the following solution:

<code class="php">$sql = "SELECT * FROM table WHERE id LIKE CONCAT('%', :id, '%')
LIMIT :offset, :limit";

$stmt = $pdo->prepare($sql);

// Turn off PDO emulation of prepared statements for MySQL
$pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);

$array = [':id' => 5];

// Bind the LIMIT parameters
$stmt->bindParam(':offset', $limit1, PDO::PARAM_INT);
$stmt->bindParam(':limit', $limit2, PDO::PARAM_INT);

// Execute the query
$stmt->execute($array);

$results = $stmt->fetchAll();</code>

By disabling PDO emulation of prepared statements (default for MySQL), it allows you to use parameterized values within the LIMIT clause. This method ensures that your queries are executed correctly with the specified parameters.

Note that turning off emulation may impact performance. For more details, refer to the documentation on PDO MySQL: Use PDO::ATTR_EMULATE_PREPARES or not?.
