Stie cineva cum se poate obtine valoarea lui HTTP Status Code prin functii de PHP4? (ex: codul 200=OK, codul 301=Moved Permanently, etc.)
In PHP5 il gasesc in primul element din array-ul returnat de get_headers().

Cu header() creezi un header. Eu vreau sa citesc din el.

Vreau sa obtin ce iti afiseaza extensia Web Developer din Firefox in tagul Information la View Response Headers, mai precis ultimul rind.

get_headers

(PHP 5)
get_headers -- Fetches all the headers sent by the server in response to a HTTP request
Description
array get_headers ( string url [, int format] )

get_headers() returns an array with the headers sent by the server in response to a HTTP request. Returns FALSE on failure.

If the optional format parameter is set to 1, get_headers() parses the response and sets the array's keys.

Example 1. get_headers() example Cod:
<?php
$url = 'http://www.example.com';

print_r(get_headers($url));

print_r(get_headers($url, 1));
?>

sau daca n-ai php 5

Cod:
<?php
if (isset($_POST['url']) && get_magic_quotes_gpc()) {
$_POST['url'] = stripslashes($_POST['url']);
}

?>

cu get_headers am avut mai multe probleme, recomand urmatoarea abordare:

$host = "www.phpromania.net";
$path = "/";

Cod:
$fp = fsockopen($host, 80, $errno, $errstr, 5); //deschid conexiune pe port 80
if (!$fp) {
print "EROARE: $errstr ($errno)\n";
return false;
} else {
$out = "GET ".$path." HTTP/1.1\r\n";
$out .= "Host: ".$host."\r\n";
$out .= "User-Agent: Mozilla/5.0 (compatible)\r\n";
$out .= "Content-type: text/html\r\n";
$out .= "Accept-Charset: iso-8859-1\r\n";
$out .= "Connection: Close\r\n\r\n";
fwrite($fp, $out);
//verificam headerele documentului
for($i=0;$i<=7;$i++){ //luam primele 7-8 linii din document care contin headerul
$html_header .= fgets($fp, 128);
}
//verificare daca headerul contine HTTP
if(ereg("HTTP/[0-9.]+ (([0-9])[0-9]{2})", $html_header, $regs)){
//print_r($regs);
[...]
