How can PHP be configured to parse the entire source code during development to avoid issues with changing function visibility?

When developing in PHP, it's important to configure the interpreter to parse the entire source code to catch any issues with changing function visibility. This can be done by setting the `zend.assertions` directive to `1` in the php.ini file. This will enable assertions and ensure that all code is parsed and checked for errors related to function visibility. 

// Enable assertions to parse the entire source code
ini_set('zend.assertions', 1);

// Your PHP code here
