<?php
$options = array(
  'http'=>array(
    'method'=>"GET",
    'header'=>"CustomHeader: yay\r\n" .
              "AnotherHeader: test\r\n"
  )
);
$context=stream_context_create($options);
$data=file_get_contents('http://www.someservice.com/api/fetch?key=1234567890',false,$context);
?>

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://www.someservice.com/api/fetch?key=1234567890');
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Header: value'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$result = curl_exec($ch);
curl_close($ch);

$context = stream_context_create(array(
'http' => array(
'method' => 'GET',
'header' => 'CUSTOM HEADER HERE',
)
));

$result = file_get_contents($url, false, $context);
