simple array retrieval

[lit108]

I am just starting php and attempting a simple program that will retrieve some data from an array

 

I have 2 files one with the function containing the array, another with the code that should select a value from the array. I have done what I thought would work however it does nothing. Any help would be greatly appreciated

 

function.php

<?PHP
function getMonthName(){
    $a=array("one","two","three","four","five");
    print_r($a);
}
?>

 

retrieve.php

<?PHP
require_once('functions.php');
$number=3;

if ($number == $a) {
    echo "$a";
}
?>

You are using variable $number as a whole number, try assigning $number variable as array, like $number[3]; and then in retrieve.php assign to $number[2] = "three"; and then compare arrays with IF.

First, the function isn't returning anything. Second, you're not invoking the function.

 

Here's what I think you want to do:

functions.php

<?php
function getMonthName($n) {
   $a=array("one","two","three","four","five");
   return($a[$n]);
}

 

main code

<?php
require_once('functions.php');
$number = 3;
echo getMonthName($number);
?>
