Searching Local Venues With Foursquare API - php

Question

I am searching foursquare for venues around my area. I cannot get the search function to work.
This is the documentation on it,
I believe my problem is in the http request but I don't get why =the result is always null or how to troubleshoot it from here.

This is my search form,
<div class="row">
<div class="col-sm-6 text-center">
<div class="signup-form">
<form class="clearfix" action="actions/fsSearch.php" method="post">
<div class="form-group">
<h3>sup bro</h3>
<input type="text" class="form-control" name="query" placeholder="do iT">
</div>
</div>
<button type="submit" name="submit" value="post" class="btn btn-huge btn-info">Search For Places!</button>
</form>
</div>
</div>
This is my search foursquare script,
<?php
$client_id = "foo";
$secret = "foo";
$redirect = "http://www.example.com/sandbox";
$query = $_POST['query'];
$fsSearch = file_get_contents("https://api.foursquare.com/v2/venues/search
?client_id=" . $client_id . "
&client_secret=" . $secret . "
&v=20140623
&ll=40.7,-74
&query=".$query);
$searchResults = json_decode($fsSearch,true);
header("Location: http://www.example.com/sandbox");
?>
Then when I var_dump($searchResults);
I get a null result.
I dont see what I am doing wrong here...
This is my try with Curl
<?php
$client_id = "foo";
$secret = "foo";
$redirect = "http://www.example.com/sandbox";
$query = $_POST['query'];
echo $query;
$ch = curl_init();
curl_setopt_array($curl, array(
CURLOPT_RETURNTRANSFER => 1,
CURLOPT_URL => "https://api.foursquare.com/v2/venues/search?client_id={$client_id}&client_secret={$secret}&v=20140623&ll=40.7,-74&query={$query}",
CURLOPT_USERAGENT => 'Mozilla/5.0 (Windows NT 5.1; rv:31.0) Gecko/20100101 Firefox/31.0'
));
$response = curl_exec($ch);
curl_close($ch);
var_dump($response);
?>

I know this is epically late, but i just got this to work by removing the line feeds in your API request and wanted to submit this encase anyone arrived here via google (like i did!)
Change this:
$fsSearch = file_get_contents("https://api.foursquare.com/v2/venues/search
?client_id=" . $client_id . "
&client_secret=" . $secret . "
&v=20140623
&ll=40.7,-74
&query=".$query);
To this:
$fsSearch = file_get_contents("https://api.foursquare.com/v2/venues/search?client_id=" . $client_id . "&client_secret=" . $secret . "&v=20140623&ll=40.7,-74&query=".$query);
