Yaf_Request_Abstract::getParam() is a method in the Yaf framework in PHP that is used to retrieve a parameter value from the current HTTP request. It is commonly used to retrieve query string parameters or form input values.

This method takes one parameter, which is the name of the parameter to retrieve. It returns the value of the parameter if found, or a default value if the parameter is not present or empty.

Here is an example usage of Yaf_Request_Abstract::getParam():


// Assuming the URL is "http://example.com/?name=John&age=25"

$request = new Yaf_Request_Http();

$name = $request->getParam('name');
// $name will be "John"

$age = $request->getParam('age');
// $age will be "25"

$unknownParam = $request->getParam('unknown', 'default');
// $unknownParam will be "default"


In this example, we create a new instance of the Yaf_Request_Http class and use the getParam() method to retrieve the values of the "name" and "age" parameters. We also demonstrate how to set a default value for a parameter that doesn't exist using the second argument of getParam().

Note that the Yaf framework is a lightweight PHP framework designed for high performance, and Yaf_Request_Abstract::getParam() is one of the methods provided by the framework to handle request parameters.
