Quick way to INSERT an array into a table

This is a useful function that I wrote to insert an array into a table in your database.

<?php
function insert_array($table, $data) {
	$cols = '(';
	$values = '(';
	foreach ($data as $key=>$value) {
		$value = addslashes($value);
		$cols .= "$key,";
		$values .= "'$value',";
	}
	$cols = rtrim($cols, ',').')';
	$values = rtrim($values, ',').')';
	$sql = "INSERT INTO $table $cols VALUES $values";
	mysql_query($sql) or die(mysql_error());
	return mysql_insert_id();
}

Here is an example of using this code:

<?php
$arr = array('title' => $_POST['title'], 'product_code' => $_POST['product_code'], 'description' => $_POST['description'], 'price' => $_POST['price']);
$product_id = insert_array("products", $arr);
?>
