Explode does not separate line correctly

I am getting below the line using cURL. The code can be found in this comment .

HTTP/1.1 200 OK ID=347 Date: Tue, 19 Feb 2013 09:15:25 GMT Server:
Apache/2.2.22 (Ubuntu) Content-length: 0 Vary: Accept-Encoding
Content-Type: text/plain; charset=ISO-8859-1

Now I want an ID from a string and for that I used explode to create an array from a space as shown below:

$getIdElem = explode(' ',$output);
echo '<pre>';print_r($getIdElem);

but I am getting Date: with id string and space before it. Array print output:

Array
(
    [0] => HTTP/1.1
    [1] => 200
    [2] => OK
    [3] => ID=347
Date:
    [4] => Tue,
    [5] => 19
    [6] => Feb
    [7] => 2013
    [8] => 09:15:25
    [9] => GMT
Server:
    [10] => Apache/2.2.22
    [11] => (Ubuntu)
Content-length:
    [12] => 0
Vary:
    [13] => Accept-Encoding
Content-Type:
    [14] => text/plain;
    [15] => charset=ISO-8859-1


)

I don't understand why it doesn't include this space in the break function. Can anyone help me with this?

Use a regular expression instead:



if (preg_match('# ID=(\d+) #', $response, $match)) { 
   $id = $match[1];
}

It is a newline before the date, not a space. Better try a regular expression to extract the bits you want.
