‣ The RFC: Allow specifying keys in list() Since PHP 5.4, we can work with a , but it’s always nice to see more consistency in the language!‣ The RFC: Square bracket syntax for array destructuring assignment Another small evolution, which makes PHP more consistent with itself and with other languages and will in some situations simplify things a bit: support for negative indexes, when working with strings, has been generalized.
Storing the colors one by one in a variable could look something like this: But what, if you want to store the states or city names of a country in variables and this time this not just three may be hundred.
It is quite hard, boring, and bad idea to store each city name in a separate variable. The multidimensional array is an array in which each element can also be an array and each element in the sub-array can be an array or further contain array within itself and so on.
While it’s not as powerful as Java Script’s array destructuring, it’s still a cool tool to have baked in the language.
Now that we know how array destructuring works, let’s move on to some practical examples.
Arrays are complex variables that allow us to store more than one value or a group of values under a single variable name.
Let's suppose you want to store colors in your PHP script.
It can modernize your code (like converting the operator on PHP 5.6) and (micro) optimize it.
If you are already using a linter to identify coding standards problems in your code, you know that fixing them by hand is tedious, especially on large projects.
Let’s start with an array of some fruits and vegetables.
Every piece of produce has an The previous example could also be interpreted as a tuple containing a status and a reason.
