## Introduction of PHP array
|
||
|
|
|
||
|
|
An array in PHP is actually an ordered map. A map is a type that associates values to keys.
|
||
|
|
This type is optimized for several different uses; it can be treated as an array, list (vector), hash table (an implementation of a map), dictionary, collection, stack, queue, and probably more.
|
||
|
|
As array values can be other arrays, trees and multidimensional arrays are also possible.
|
||
|
|
|
||
|
|
|
||
|
|
Here is an example:
|
||
|
|
```
|
||
|
|
<?php
|
||
|
|
// array without keys
|
||
|
|
$bikes = array("Suzuki","BMW","Yamaha");
|
||
|
|
echo "I like " . $bikes[0] . ", " . $bikes[1] . " and " . $bikes[2] . ".";
|
||
|
|
?>
|
||
|
|
```
|
||
|
|
|
||
|
|
PHP array has so many functions to work with. Here is all list sorted: <a href="https://www.w3schools.com/php/php_ref_array.asp" target="_blank">Functions</a>

## Associative arrays
|
||
|
|
|
||
|
|
PHP arrays can be used as key and value like map. It can be accessed by key too.
|
||
|
|
|
||
|
|
Here is an simple example:
|
||
|
|
```
|
||
|
|
<?php
|
||
|
|
$array = array(
|
||
|
|
"foo" => "bar",
|
||
|
|
"bar" => "foo",
|
||
|
|
);
|
||
|
|
|
||
|
|
echo $array['bar'];
|
||
|
|
|
||
|
|
```
|
||
|
