When does PHP check for Fatal Error?

Reviewing Property Declaration In PHP

This approach usually brings a bit of performance, by processing a list of arguments […]

Literal candidates for constants

Literal candidates for constants Literals are hard coded values in the source. Once they are written, they can’t be changed without altering the source code. This is always fine, initially, while building the first implementations. Yet, later, it may arise that such literal have to be managed from different points of the code. This is […]
