Question

have some headers like:

HTTP/1.1 100 Continue
HTTP/1.1 302 Found
HTTP/1.1 200 OK
HTTP/1.1 400 Not Found

so, I need to get 2 parts:

[200] => [OK]
[400] => [Not Found]

I need a way to use preg_match_all and get those values, but need to preserve the spaces at Not Found

have this code:

preg_match_all( '/([0-9]{3}) ([A-Za-z0-9+]*)/', $headers, $matches );

Works with 1-3 example headers.

Any ideas?

Answer 1

For the single line and for the text in general

$str = "HTTP/1.1 100 Continue
HTTP/1.1 302 Found
HTTP/1.1 200 OK
HTTP/1.1 400 Not Found";

// for the values in the string, one on each line
preg_match_all('#(\d{3})\s+([\w\s]+)$#m', $str, $matches);
var_dump($matches);  // captures a new line symbol if exists

// for single value in the string
$str = "HTTP/1.1 400 Not Found";
preg_match('#(\d{3})\s+([\w\s]+)$#', $str, $matches);
var_dump($matches);

So, do you have each header on a new line or not?
