    function is :
    
function check_requirements() {
   $requirements = array ();
   #PHP Vesion
   $result        = array ('req' =>('PHP Version >= 4.1'));
   $result['ok']  = @ version_compare (@ phpversion(), '4.1', '>=');
   $result['txt'] = '('.@ phpversion().')';
   if (!$result['ok'])
      $result['txt'] .= ('script may not work. Please upgrade!');

   $requirements[] = $result;

   #Server API
   $result       = array ('req' => ('Server API'));
   $result['ok'] = php_sapi_name() != "cgi";
   if ($result['ok'])
      $result['txt'] = '('.php_sapi_name().')';
   else
      $result['txt'] = ('CGI mode is likely to have problems.');

   $requirements[] = $result;

   #GD support
   $result       = array ('req' => ('GD Support (for visual confirmations)'));
   $result['ok'] = extension_loaded ('gd');
   if ($result['ok'])
   {
      ob_start();
      @ phpinfo(8);
      $module_info = @ ob_get_contents();
      @ ob_end_clean();
      if (preg_match ("/\bgd\s+version\b[^\d\n\r]+?([\d\.]+)/i", $module_info, $matches))
         $result['txt'] = '('.$matches[1].')';
      unset ($module_info, $matches);
   }
   else
      $result['txt'] = ('Visual confirmation functionality will not be available.');

   $requirements[] = $result;

   #Session Save Path writable?
   $result = array ('req' => ('Session Save Path writable?'));
   $sspath = @ ini_get ('session.save_path');
   if (preg_match ("`.+;(.*)`", $sspath, $matches))

      $sspath = $matches[1];
      unset ($matches);

   if (!$sspath)

      $result['txt'] = str_replace ('##sspath##', $sspath, $r['txt']);
   }
   $requirements[] = $result;

   #MySQL Support

    You can't convert a function into an array, they're two completely different things...

    $requirements[] = $result;

   return $requirements;
}
    PHP:
    This function is already returning an array. Try following

    
$my_arr = check_requirements(); 
print_r($my_arr);// print array returned from function
    PHP:
    It should display all array elements if function is working without errors.

    I think this is what you want... The following works because the function returns an array

    
$array = check_requirements();
print_r($array);

function check_requirements() {
   $requirements = array ();
   #PHP Vesion
   $result        = array ('req' =>('PHP Version &gt;= 4.1'));
   $result['ok']  = @ version_compare (@ phpversion(), '4.1', '>=');
   $result['txt'] = '('.@ phpversion().')';
   if (!$result['ok'])
      $result['txt'] .= ('script may not work. Please upgrade!');

   $requirements[] = $result;

   #Server API
   $result       = array ('req' => ('Server API'));
   $result['ok'] = php_sapi_name() != "cgi";
   if ($result['ok'])
      $result['txt'] = '('.php_sapi_name().')';
   else
      $result['txt'] = ('CGI mode is likely to have problems.');

   $requirements[] = $result;

   #GD support
   $result       = array ('req' => ('GD Support (for visual confirmations)'));
   $result['ok'] = extension_loaded ('gd');
   if ($result['ok'])
   {
      ob_start();
      @ phpinfo(8);
      $module_info = @ ob_get_contents();
      @ ob_end_clean();
      if (preg_match ("/\bgd\s+version\b[^\d\n\r]+?([\d\.]+)/i", $module_info, $matches))
         $result['txt'] = '('.$matches[1].')';
      unset ($module_info, $matches);
   }
   else
      $result['txt'] = ('Visual confirmation functionality will not be available.');

   $requirements[] = $result;

   #Session Save Path writable?
   $result = array ('req' => ('Session Save Path writable?'));
   $sspath = @ ini_get ('session.save_path');
   if (preg_match ("`.+;(.*)`", $sspath, $matches))
   {
      $sspath = $matches[1];
      unset ($matches);
   }

   if (!$sspath)
   {
      $result['ok']  = false;
      $result['txt'] = ('Warning: <span class="item">session.save_path ('.$sspath.')</span> is not set.');

      $result['txt'] = str_replace ('##sspath##', $sspath, $r['txt']);
   }
   $requirements[] = $result;

    You don't 'call' arrays, you call functions, which then return a result (this may be an array). I'm not sure if you should be messing around with PHP if you don't know the difference between these two concepts, but to print the contents of an array you can use:

    var_dump($array);

    Don't learn php the hard way, go get a book, you will learn more reading the book than hacking around in 1 year
