The getNewCriterion is a function in the PHP language that is used to define criteria for selecting or filtering data from a database or any dataset. It helps to create a new criterion object, which can be used to build more complex queries using logical operators like AND and OR.
One package library that utilizes the getNewCriterion function is the Propel ORM (Object-Relational Mapping) library. The Propel library is an abstraction layer for working with databases in PHP, which provides a simple and intuitive API for working with database objects. Here are some examples of using the getNewCriterion function in Propel:
1. To select all users whose age is greater than 18:
$c = new Criteria(); $c->add(UserPeer::AGE, 18, Criteria::GREATER_THAN);
2. To select all orders for a given product:
$c = new Criteria(); $c->add(OrderPeer::PRODUCT_ID, $product->getId());
3. To select all blog posts published in the last 30 days:
In the examples above, the Criteria object is created using the new keyword, and the add method is used to create a new criterion object, which is then added to the Criteria object. The first argument to the add method is the database column to filter by, the second argument is the value to filter on, and the third argument (optional) is the comparison operator to use.
In conclusion, the getNewCriterion function is a useful tool for building complex queries in PHP, and it is commonly used in libraries like Propel to provide a simple API for working with database objects.
