What is an Array?

An array is a special variable that can hold more values at the some time.

In PHP, there are three types of arrays:

• Indexed or Numeric arrays - Matrix that contains a numeric index
• Associative arrays - Array containing named keys
• Multidimensional arrays - Arrays that containing one or more arrays

Create an Array in PHP
array() function is used to create an array:

Syntax:

To loop through array and display all the values of an Indexed (Numeric) array, we use a "for" loop, as this:

<?php

  $my_cars = array("Peugeot", "BMW", "Volvo", "Toyota", "Renault");

  $arr_length = count($my_cars);


for($a = 0; $a < $arr_length; $a++) {

  echo $my_cars[$a];

  echo "<br>";

  }

  ?>

Associative arrays are more o less the same as numeric arrays in term of functionality but they are different in terms of their index

Associative arrays are arrays that use named keys that you assign to them.

We show you an example: Loop Through an Associative Array

<?php

  $user_age = array("Chris"=>"32", "Benony"=>"27",

   "Johny"=>"23", "Ana-Marie"=>"29", "Maru"=>"43");


	foreach($user_age as $a => $a_value) {

 	 echo "Age for " . $a . ", is =" . $a_value;

 	 echo "<br>";

  }

  ?>
      

A multi-dimensional array is an array containing one or more arrays.

<?php

$carsstsold = array (

array("Peugeot",24,14),

array("Renault",18,11),

array("BMW",9,2),

array("Land Rover",17,12),

array("Volvo",16,7)

);



echo $carsstsold[0][0].": - In stock: ".$carsstsold[0][1].", sold: ".$carsstsold[0][2].".<br>";

echo $carsstsold[1][0].": - In stock: ".$carsstsold[1][1].", sold: ".$carsstsold[1][2].".<br>";

echo $carsstsold[2][0].": - In stock: ".$carsstsold[2][1].", sold: ".$carsstsold[2][2].".<br>";

echo $carsstsold[3][0].": - In stock: ".$carsstsold[3][1].", sold: ".$carsstsold[3][2].".<br>";

echo $carsstsold[4][0].": - In stock: ".$carsstsold[4][1].", sold: ".$carsstsold[4][2].".<br>";
