I am trying to access my ec2's public hostname from inside the instance.
I would like to run this command
curl http:// 169 254.169.254/latest/meta-data/public-hostname
inside a php script and save the response to a variable. How can I do this?

You can do like this
<?php
//URL of targeted site
$url = "http://www.yahoo.com/";
$ch = curl_init();
// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// grab URL and pass it to the browser
$output = curl_exec($ch);
//echo $output;
// close curl resource, and free up system resources
curl_close($ch);
?>
The $output variable contains the response.

This worked for me. The only change I made was the url. Not sure what that other comment was all about.
Shankar Damodaran provided an example of how to retrieve the response from a curl request, but specifically it is the
CURLOPT_RETURNTRANSFER that does as it says and returns the result from curl_exec
