Mailchimp Api Subscriber Check via php - php

Question

I am trying to check if an e-mail address a user enters already is in the list of subscribers or not.
This is what I have tried so far:
<?php
$apikey = 'apikey';
$list_id = 'listid';
$chunk_size = 4096; //in bytes
$url = 'http://us14.api.mailchimp.com/export/1.0/list?apikey='.$apikey.'&id='.$list_id;
/** a more robust client can be built using fsockopen **/
$handle = #fopen($url,'r');
if (!$handle) {
echo "failed to access url\n";
} else {
$i = 0;
$header = array();
while (!feof($handle)) {
$buffer = fgets($handle, $chunk_size);
if (trim($buffer)!=''){
$obj = json_decode($buffer);
if ($i==0){
//store the header row
$header = $obj;
} else {
//echo, write to a file, queue a job, etc.
echo $obj[0];
}
$i++;
}
}
fclose($handle);
}
?>
This will return all email subscribers. I am trying to narrow it down to the specific e-mail the user entered, but I am stuck and don't know how to do it?

if ($obj[0] == "myemail#gmail.com") { echo "XXXXXXX";} else { }
}
$i++;
