Question

Consider the following PHP cURL command:

$url = 'http://bit.ly/faV1vd';

$_h = curl_init();
curl_setopt($_h, CURLOPT_HEADER, 1);
curl_setopt($_h, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($_h, CURLOPT_HTTPGET, 1);
curl_setopt($_h, CURLOPT_URL, $url);
curl_setopt($_h, CURLOPT_DNS_USE_GLOBAL_CACHE, false );
curl_setopt($_h, CURLOPT_DNS_CACHE_TIMEOUT, 2 );

$return = curl_exec($_h);

This returns:

HTTP/1.1 301 Moved
Server: nginx
Date: Sun, 29 Apr 2012 12:48:07 GMT
Content-Type: text/html; charset=utf-8
Connection: keep-alive
Set-Cookie: _bit=4f9d3887-00215-020af-2f1cf10a;domain=.bit.ly;expires=Fri Oct 26 12:48:07 2012;path=/; HttpOnly
Cache-control: private; max-age=90

MIME-Version: 1.0
Content-Length: 209

I want to split the header info into an array, as follows

[Status] => HTTP/1.1 301 Moved,
[Server] => nginx,
[Date] => Sun, 29 Apr 2012 12:48:07 GMT,
...
[Content-Length] => 209

So:
– the first line (HTTP/1.1 301 Moved) should be the value of [Status]
– all other header info should be split on :

I’m not succeeding in splitting the header info:

explode("\r\n\r\n", $return);
explode("\r\n", $return);

This doesn’t split the header into an array (to further split on :, etc. as expected. What am I doing wrong?

Answer 1

Use this to split your header into an array

$myarray = array();
$data = explode("\n",$return);

$myarray['status'] = $data[0];

array_shift($data);

foreach($data as $part){
     $middle = explode(":",$part);
     $myarray[trim($middle[0])] = trim($middle[1]);
}

print_r($myarray);

As well as use curl_setopt($_h, CURLOPT_NOBODY, 1);
if you need to return only header.
