If you try to use the same key multiple times in an array, PHP will ignore all other key-value pairs except the last one. There are two important points that you should remember when creating associate arrays with key pairs.įirst, the key always has to be unique.
The other method is to put all elements inside.
One is to use array() to specify the elements as key-value pairs.
There are two different ways of creating arrays. Every PHP developer must know how to use them and how to combine array functions to make code readable and short.Īlso, there is a presentation with given code examples, so you can download it from the related links and show it to your colleagues to build a stronger team. The solution is to use the strict checking option.In this tutorial, I am going to make a list of common PHP array functions, with examples of usage and best practices. It is completely correct behaviour, due to PHP's leniency on variable types, but in "real-life" is almost useless. Loose checking returns some crazy, counter-intuitive results when used with certain arrays.
