class JS{

	//generic and maybe not the desired results xD

	function value($o){

		if($o === null)

			return 'null';

		$t = strtolower(gettype($o));

		if($t == 'string' && is_numeric($o) && ($o[0] || strlen($o) == 1) || in_array($t, array('double', 'integer')))

			$t = 'number';

		elseif($t == 'string' && preg_match('@^\d{4}(?:-\d{1,2}){1,2}(?: (?:\d{1,2}:){2}\d{1,2})?$@', $o)) //strtotime works also with "strange" values strtotime('x')

			$t = 'object';

		elseif(!in_array($t, array('boolean', 'string', 'array', 'object')))

	}

	function fromNumber($o){

	}

	}

	function fromBoolean($o){

		return $o ? 'true' : 'false';

	}

	//$q = should quote? 

	//$c = char that will be used to quote

	function fromString($o, $q = true, $c = '"'){

		return ($p = $q ? $c : '') . preg_replace('/\r\n|\n\r|\r/', '\n', str_replace($c, '\\' . $c, str_replace('\\', '\\\\', $o))) . $p;

	}

	function fromArray($o){

		$s = '';

		foreach($o as $v)

		return '[' . $s . ']';

	}

	function fromDate($o){

		(is_numeric($o) && $o = +$o) || ($o = strtotime($o)) > 0 || ($o = mktime());

		$o = explode(',', date('Y,n,j,G,i,s', $o));

		foreach($o as $i => $v)

			$o[$i] = +$v;

		return 'new Date(' . implode(',', $o)  . ')';

	}

}

Example



$o = new stdClass;

$o->abc = 123;

echo implode("\n
", array(

	JS::value('1984-07-22 11:30:12'),

	JS::value('Test'),

	JS::value(1234),

	JS::value(true),

	JS::value(array(1,2,3)),

	JS::value(array('lala' => 'x')),

	JS::value($o)

));

Cannot modify header information - headers already sent by FIX

dezmarie (Desirae Beberniss) — Sun, 10 Sep 2006 03:54:29 GMT

Buffers output and eliminates problem with spaces/line breaks at the beginning/end of files. Make sure to place ob_start(); before header(); is called.



ob_start();



header("Location: somepage.php"); //Redirect



ob_end_flush();

exit;
