My Timer() class fails, need a hand

[ppowell]

I wrote a class called Timer that will attempt to time how long it takes to evaluate and load a page.

/**
 * Class for implemention of various timers
 *
 * @author Phil Powell
 * @version 1.0.0
 * @package MU-SPIN
 */
class Timer extends View {

/**
 * @access private
 * @var float $startTime
 */
var $startTime;

/**
 * @access private
 * @var mixed $url
 */
var $url;

/**
 * Constructor.  Set optional URL property
 *
 * @access public
 * @param mixed $url (optional)
 */
function Timer($url = '') {				// CONSTRUCTOR
	$this->url = $url;
}

//-------------------------------------------- --* GETTER/SETTER METHODS *-- ------------------------------------------

/**
 * Retrieve $url property
 *
 * @access private
 * @return mixed $url
 */
function &getURL() {					// STRING METHOD
 	return $this->url;
}

/**
 * Set the time
 *
 * @access private
 * @param float $timeKeeper (reference)
 * @return float $timeKeeper
 */
function &setTime(&$timeKeeper) {			// STATIC FLOAT METHOD
	$start = microtime();
	$start = explode(' ', $start);
	$start = (float)$start[1] + (float)$start[0];
	$timeKeeper = $start;
	return $timeKeeper;
}

/**
 * Set $url property
 *
 * @access private
 * @param mixed $url
 */
function &setURL($url) {				// VOID METHOD
	if (is_object($this) && !$this->url) $this->url = $url;
}

//--------------------------------------------- --* END OF GETTER/SETTER METHODS *-- -------------------------------

/**
 * Display HTML based on given URL property value
 *
 * @access public
 * @param mixed $url (optional)
 * @return mixed HTML
 */
function &displayHTML($url = '') {			// STATIC HTML STRING METHOD
	if (is_object($this) && !$this->getURL() && $url) $this->setURL($url);
	if (is_object($this)) $url = $this->getURL();
	if ($url && ini_get('allow_url_fopen')) {
	 $this->setTime($this->startTime);	// SET START TIME
	 $html = @file_get_contents($url);
	 $timer = $this->setTime($timer);
	 $html = preg_replace('/(.*<body[^>]*>)(.*)(<\/body>.*)/i', '$1<p><b>' . ($timer - $this->startTime) . ' seconds</b>' . '$2$3', $html);
	}
	return $html;
}

}

However, the problem lies in the displayHTML() method whereby the line:

$html = @file_get_contents($url);

will produce wrong results if $url happens to point to a URL that is either $COOKIE or $SESSION - dependent.

What on earth do I do in the method to ensure those are available prior to the "scrape" of the URL? I have no clue what to do at this point regarding that and this class produces false results.

Furthermore, the preg_replace() line also fails to display the time anywhere in the URL:

$html = preg_replace('/(.*<body[^>]*>)(.*)(<\/body>.*)/i', '$1<p><b>' . ($timer - $this->startTime) . ' seconds</b>' . '$2$3', $html);[/{PHP] - the pattern match fails every time.

Wow.

I updated the class via a friend's suggestion of using CURL (this will require that --with-curl option is on in PHP):

/**
 * Class for implemention of various timers
 *
 * @author Phil Powell
 * @version 1.0.0
 * @package MU-SPIN
 */
class Timer extends View {

/**
 * @access private
 * @var float $startTime
 */
var $startTime;

/**
 * @access private
 * @var mixed $url
 */
var $url;

/**
 * Constructor.  Set optional URL property
 *
 * @access public
 * @param mixed $url (optional)
 */
function Timer($url = '') {				// CONSTRUCTOR
	$this->url = $url;
}

//-------------------------------------------- --* GETTER/SETTER METHODS *-- ------------------------------------------

/**
 * Retrieve $url property
 *
 * @access private
 * @return mixed $url
 */
function &getURL() {					// STRING METHOD
 	return $this->url;
}

/**
 * Set the $_POST curl set_opt options per instance of $_POST
 * 
 * @access private
 * @param resource $ch (reference) curl reference
 */
function &setPOSTCurlSetOpt(&$ch) {			// STATIC VOID METHOD
	if (@sizeof($_POST) > 0) curl_setopt($ch, CURLOPT_POSTFIELDS, serialize($_POST));
}


/**
 * Set the time
 *
 * @access private
 * @param float $timeKeeper (reference)
 * @return float $timeKeeper
 */
function &setTime(&$timeKeeper) {			// STATIC FLOAT METHOD
	$start = microtime();
	$start = explode(' ', $start);
	$start = (float)$start[1] + (float)$start[0];
	$timeKeeper = $start;
	return $timeKeeper;
}

/**
 * Set $url property
 *
 * @access private
 * @param mixed $url
 */
function &setURL($url) {				// VOID METHOD
	if (is_object($this) && !$this->url) $this->url = $url;
}

//--------------------------------------------- --* END OF GETTER/SETTER METHODS *-- -------------------------------

/**
 * Display HTML based on given URL property value
 *
 * @access public
 * @param mixed $url (optional)
 * @return mixed HTML
 */
function &displayHTML($url = '') {			// STATIC HTML STRING METHOD
	global $projectFolderName, $PHPSESSID;
	if (is_object($this) && !$this->getURL() && $url) $this->setURL($url);
	if (is_object($this)) $url = $this->getURL();
	if ($url && ini_get('allow_url_fopen')) {
	 if (!$_COOKIE['PHPSESSID']) {
	  if (preg_match('/\?/i', $url)) $url .= "&PHPSESSID=$PHPSESSID"; else $url .= "?PHPSESSID=$PHPSESSID";
	 }
	 $this->setTime($this->startTime);	// SET START TIME
	 // grab URL and pass it to the browser
	 ob_start();
	  $ch = curl_init();
	  curl_setopt($ch, CURLOPT_COOKIE, $_COOKIE["$projectFolderName"]);
	  $this->setPOSTCurlSetOpt($ch);
	  curl_setopt($ch, CURLOPT_HEADER, 1);
	  curl_setopt($ch, CURLOPT_URL, $url);
	  curl_exec($ch);
	  curl_close($ch);
	  $html = ob_get_contents();
	 ob_end_clean();
	 // close curl resource, and free up system resources
	 $timer = $this->setTime($timer);
	 $html = preg_replace('/(.*<body[^>]*>)(.*)(<\/body>.*)/i', '$1<p><b>' . ($timer - $this->startTime) . ' seconds</b>' . '$2$3', $html);
	}
	return $html;
}

}

Now what happens is that the URL is produced and comes back, without any timer information unfortunately, however, the HTTP header for "Set-cookie" remains unchanged even though $_COOKIE exists with multiple values and need to be passed into the HTTP header.

So now I need a really good CURL PHP expert!

Thanx
