How to bind multiple params to prepare statement [duplicate] - php

Question

Is there's an easy way of binding multiple values in PDO without repitition ? Take a look at the following code :
$result_set = $pdo->prepare("INSERT INTO `users` (`username`, `password`, `first_name`, `last_name`) VALUES (:username, :password, :first_name, :last_name)");
$result_set->bindValue(':username', '~user');
$result_set->bindValue(':password', '~pass');
$result_set->bindValue(':first_name', '~John');
$result_set->bindValue(':last_name', '~Doe');
$result_set->execute();
Here, I binded values in a repepeated way which is 4 times. So is there's an easy way of binding multiple values in PDO ?

Answer 1

You can always bind values within the arguments of execute() as long as you're fine with the values being treated as PDO::PARAM_STR (string).
$result_set = $pdo->prepare("INSERT INTO `users` (`username`, `password`, `first_name`, `last_name`) VALUES (:username, :password, :first_name, :last_name)");
$result_set->execute(array(
':username' => '~user',
':password' => '~pass',
':first_name' => '~John',
':last_name' => '~Doe'
));
You can use the array passed just like any array:
$user = "Nile";
$pdo->execute(array(":user" => $user));

If you want to bind based on type (string, int, etc), then no. If you're fine with binding everything as a string:
$stmt = $db->prepare("...");
$stmt->execute(array(
'foo' => 'bar',
'something' => 'else',
'third' => 'thing',
));

To truly never type anything twice, you can use an array to supply the data, and use a function on that same array to output the binding portion of the MySQL query. For example:
function bindFields($fields){
end($fields); $lastField = key($fields);
$bindString = ' ';
foreach($fields as $field => $data){
$bindString .= $field . '=:' . $field;
$bindString .= ($field === $lastField ? ' ' : ',');
}
return $bindString;
}
The data and column names come from a single associative array ($data). Then, use bindFields($data) to generate a string of column = :column pairs to concatenate into the MySQL query:
$data = array(
'a_column_name' => 'column data string',
'another_column_name' => 'another column data string'
);
$query = "INSERT INTO tablename SET" . bindFields($data);
$result = $PDO->prepare($query);
$result->execute($data);
bindFields($data) output:
a_column_name=:a_column_name,another_column_name=:another_column_name
