Synopsis
If you’ve not read my ‘The first step’ posts (all three – one , two and three ) and don’t understand PHP, then please do before continuing. The code presented will be on the same setup and the post will reference this.
Passing variables into functions can be done in one of two ways:
- By value
- By reference
In this post I will explain both and compare the effect on an array of numbers.
