; cgi.fix_pathinfo provides *real* PATH_INFO/PATH_TRANSLATED support for CGI.  PHP's
; previous behaviour was to set PATH_TRANSLATED to SCRIPT_FILENAME, and to not grok
; what PATH_INFO is.  For more information on PATH_INFO, see the cgi specs.  Setting
; this to 1 will cause PHP CGI to fix its paths to conform to the spec.  A setting
; of zero causes PHP to behave as before.  Default is 1.  You should fix your scripts
; to use SCRIPT_FILENAME rather than PATH_TRANSLATED.

; FastCGI under IIS (on WINNT based OS) supports the ability to impersonate

; cgi.rfc2616_headers configuration option tells PHP what type of headers to

ya encontre como poder hacerlo

Código PHP:

$data = file("php.ini");
$out = array();
foreach($data as $line) {
     if (strpos($line, ';') === false ) {
         $out[] = $line;
     }
}
