PDO use quote with an array

问题

I'm new in PDO

$sFields = "'".implode("', '", $fields)."'";
$sColumns = implode(", ", $columns);
$sql = "INSERT INTO $table ($sColumns) VALUES ($sFields)";

What is the shortest way to use PDO::quote on each value I want to insert.

I tried

$fields = array_map('$bdd->quote', $fields);

but it returns:

Warning: array_map() expects parameter 1 to be a valid callback, function '$bdd->quote' not found or invalid function name

回答1:

There is other way than concat sql string.

$sColumns = implode(", ", $columns);
$sFields = implode(',', array_fill(0, count($fields), '?'));
$sql = "INSERT INTO $table ($sColumns) VALUES ($sFields)";

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

回答2:

Try

$fields = array_map(array($bdd, 'quote'), $fields);
