Question

I’ve started using PHP lately… all is good except one thing.
I am trying to call a function from another php file… but it’s not working.
It’s probably really simple, but I haven’t found anything useful to solve it.

I’ve used “required_once ” but it still does not work.
Does anyone know where I’m going wrong?

<?php
require_once "/Applications/MAMP/htdocs/me/database_functions.php";
require_once "/Applications/MAMP/htdocs/me/encode_decode.php";

if (isset($_POST['url']) && $_POST['url'] != "http://")
{
//Get the url posted
$long_url = $_POST['url'];

//Create record in long_url table and return it's id
$long_id = create_long_url($long_url);

Everything works so far.. But
the problem is this next function call.. it doesn’t even go into the function.

$short_url = $encode($long_id);


}...............etc...

encode_decode.php looks a bit like this…

<?php //encode_decode.php


function encode($number)
{
echo "<br />in encode";
//Encode numer to 6 char 
$s = strtr(rtrim(base64_encode(pack('i', $number)), '='), '+/', '-_');

echo $s;

return $s;
}

Any help is greatly appreciated…

You don’t need the $ before your function call

$short_url = $encode($long_id);

should be

$short_url = encode($long_id);
