Very simple random array

[3raser]

I'm learning more stuff, and I don't understand why this isn't working. It's not returning any results.

 

test_index.php

<?php
include ("test_functions.php");

$array = array("Welcome", "Welcome back", "Good-bye");

echo ParseTest($array, $output);
?>

 

test_functions.php

<?php

function ParseTest($array) {
$output = array_rand($array,1);
echo "The random result returned: ". $array[$output['0']] ."";
}

?>

You're not returning anything from the function. Replace the "echo" with a "return":

<?php
function ParseTest($array) {
    $output = array_rand($array,1);
    return "The random result returned: ". $array[$output];
}
?>

 

Also, your function has only one parameter, so you should call it using one parameter.

Code works, thanks!

 

And what do you mean by this?

You declare your function as

<?php
function ParseTest($array)
?>

with one parameter, so you should have only one parameter when you call it:

<?php
$x = ParseTest($ary);
?>
