============

Each item in an array is numbered starting from 0. For example, when we create an array:

```
<pre style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0); color: rgb(197, 200, 198); border-radius: 2px; padding: 7px 10px; font-size: 15px; line-height: 22px; background-color: rgb(35, 44, 49);">
```
<span class="preprocessor" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0); color: rgb(203, 75, 22);"><span class="preprocessor" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);"><?php</span></span>
<span class="variable" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0); color: rgb(181, 137, 0);"><span class="variable" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">$myArray</span></span> = <span class="keyword" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0); color: rgb(178, 148, 187);"><span class="keyword" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">array</span></span>(<span class="string" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0); color: rgb(181, 189, 104);"><span class="string" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">"do"</span></span>, <span class="string" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0); color: rgb(181, 189, 104);"><span class="string" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">"re"</span></span>, <span class="string" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0); color: rgb(181, 189, 104);"><span class="string" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">"mi"</span></span>);
<span class="preprocessor" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0); color: rgb(203, 75, 22);"><span class="preprocessor" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">?></span></span>
```
```

Therefore, we can access a particular item of the array using its position, like this:

```
<pre style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0); color: rgb(197, 200, 198); border-radius: 2px; padding: 7px 10px; font-size: 15px; line-height: 22px; background-color: rgb(35, 44, 49);">
```
<span class="preprocessor" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0); color: rgb(203, 75, 22);"><span class="preprocessor" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);"><?php</span></span>
<span class="variable" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0); color: rgb(181, 137, 0);"><span class="variable" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">$myArray</span></span> = <span class="keyword" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0); color: rgb(178, 148, 187);"><span class="keyword" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">array</span></span>(<span class="string" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0); color: rgb(181, 189, 104);"><span class="string" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">"do"</span></span>, <span class="string" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0); color: rgb(181, 189, 104);"><span class="string" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">"re"</span></span>, <span class="string" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0); color: rgb(181, 189, 104);"><span class="string" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">"mi"</span></span>);

<span class="keyword" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0); color: rgb(178, 148, 187);"><span class="keyword" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">echo</span></span> <span class="variable" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0); color: rgb(181, 137, 0);"><span class="variable" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">$myArray</span></span>[<span class="number" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0); color: rgb(222, 147, 95);"><span class="number" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">0</span></span>]
<span class="comment" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0); color: rgb(150, 152, 150); font-style: italic;"><span class="comment" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">// outputs "do"</span></span>
<span class="preprocessor" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0); color: rgb(203, 75, 22);"><span class="preprocessor" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">?></span></span>
```
```
