Question

I’m trying to create a signature request for amazon’s AWS api using PHP. I’m not too familiar with PHP so this question might seem extremely obvious, so for that I’m sorry –

Amazon provides sample code for generating the signature request to use their API – which can be found here:

http://aws.amazon.com/code/AWIS/402

Their instructions state simply:

Run php urlinfo.php ACCESS_KEY_ID SECRET_ACCESS_KEY site

But I’m not sure how to “run” a php file. My instinct was to include the php file so I could make a call to its public urlInfo function:

UrlInfo($accessKeyId, $secretAccessKey, $site)

but if I include it:

<?php require_once ('urlinfo.php'); ?>

The page automatically generates the message:

Usage: ACCESS_KEY_ID SECRET_ACCESS_KEY site

So how do I call this php file from my index file and pass it the parameters it requires?

Answer 1

The urlinfo.php script was intended to be ran via PHP command line interface and expects arguments passed on via cli.

If you remove the following portion of the code:

if (count($argv) < 4) {
    echo "Usage: $argv[0] ACCESS_KEY_ID SECRET_ACCESS_KEY site\n";
    exit(-1);
}
else {
    $accessKeyId = $argv[1];
    $secretAccessKey = $argv[2];
    $site = $argv[3];
}

And then do:

$accessKeyId = "youkeyid";
$secretAccessKey = "yoursecret"; 
$site = "yoursite";

include('urlinfo.php');

It will work as expected.
