Answer: Use the Array Key or Index
If you want to access an individual value form an indexed, associative or multidimensional array you can either do it through using the array index or key.
Let's check out the following example to understand how it basically works:
Example
Try this code »<?php
// Indexed array
$sports = array("Baseball", "Cricket", "Football", "Shooting");
// Associative array
$cities = array("France"=>"Paris", "India"=>"Mumbai", "UK"=>"London", "USA"=>"New York");
// Multidimensional array
$superheroes = array(
array(
"name" => "Peter Parker",
"character" => "Spider-Man",
),
array(
"name" => "Tony Stark",
"character" => "Iron-Man",
),
array(
"name" => "Clark Kent",
"character" => "Super-Man",
)
);
echo $sports[0]; // Outputs: Baseball
echo "<br>";
echo $sports[1]; // Outputs: Cricket
echo "<br>";
echo $cities["France"]; // Outputs: Paris
echo "<br>";
echo $cities["USA"]; // Outputs: New York

echo $superheroes[0]["name"]; // Outputs: Peter Parker
