In this serie of exercises, you will mainly play with animal emojis. Why? Because emojis are short, fun and animals are cutes !

Attention

Emojis are treated as characters (strings), not as image. '🐒' is like an 'A' or a 'W', so you should always use quotes around to display it.

💪 Challenge

In this challenge, you will have to find a better name for the variable $var, according to the naming rules best practices.

in English
no abbreviation
in camelCase (in PHP, other languages could have other rules for variable format)
meaningful that means the variable name should be clear and reflect data it refers to.

Let's start, copy/paste the code below in your IDE and try to find an appropriate name for each line!

💡 Help

Brackets [] are used to declare an array, that means a group of data, you will learn more about array very soon. Arrays contain multiple datas, so, most of the time, you should use a plural name.

php

$var = '🐒';
$var = '🦍';
$var = '🦧';
$var = '🐕';
$var = '🐺';
$var = '🦊';

$var = ['🐒', '🦍', '🦧'];
$var = ['🐒', '🦍', '🦧', '🐺', '🐅', '🐷', '🐘', '🐎'];
$var = ['🐋', '🐬'];
