	  $live_time = time();

  return mktime( gmdate("H", $live_time), gmdate("i", $live_time), gmdate("s", $live_time), gmdate("m", $live_time), gmdate("d", $live_time), gmdate("Y", $live_time));
}

3. PHP (Encode PHP Tags)Convert PHP tags to entities

{
    return str_replace(array('<?php', '<?PHP', '<?', '?>'),  array('<?php', '<?PHP', '<?', '?>'), $live_string);
}

4. PHP Simple Check the String is Alpha

function check_live_alpha_numeric($live_string)
{
   return ( ! preg_match("/^([a-z0-9])+$/i", $live_string)) ? FALSE : TRUE;

6. Word Limiter –PHP Limits a string to N number of words

function word_live_limiter($live_string, $limit = 100, $last_char = '…')
{
	if (trim($live_string) == '')
	{
	  return $live_string;
	}

	preg_match('/^\s*+(?:\S++\s*+){1,'.(int) $limit.'}/', $live_string, $matches);

	if (strlen($live_string) == strlen($matches[0]))
	{
	  $last_char = '';
	}

	return rtrim($matches[0]).$last_char;
}

7. PHP Character Limiter Example

function live_character_limiter($live_string, $max = 500, $last_char = '…')
{
	if (strlen($live_string) < $max)
	{
		return $live_string;
	}

	$live_string = preg_replace("/\s+/", ' ', str_replace(array("\r\n", "\r", "\n"), ' ', $live_string));

	if (strlen($live_string) <= $max)
	{
		return $live_string;
	}

	$response = "";
	foreach (explode(' ', trim($live_string)) as $val)
	{
		$response .= $val.' ';

		if (strlen($response) >= $max)
		{
			$response = trim($response);
			return (strlen($response) == strlen($live_string)) ? $response : $response.$last_char;
		}
	}
}

8. PHP Generate Random String

function GUID_randomstring($cat = 'alnum', $len = 8)
{
  switch($cat)
  {
	  case 'basic'	: return mt_rand();
		  break;
	  case 'alnum'	:
	  case 'numeric'	:
	  case 'nozero'	:
	  case 'alpha'	:

			  switch ($cat)
			  {
				  case 'alpha'	:	$live_pool = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';
					  break;
				  case 'alnum'	:	$live_pool = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';
					  break;
				  case 'numeric'	:	$live_pool = '0123456789';
					  break;
				  case 'nozero'	:	$live_pool = '123456789';
					  break;
			  }

			  $live_string = '';
			  for ($i=0; $i < $len; $i++)
			  {
				  $live_string .= substr($live_pool, mt_rand(0, strlen($live_pool) -1), 1);
			  }
			  return $live_string;
		  break;
	  case 'unique'	:
	  case 'md5'		:

				  return md5(uniqid(mt_rand()));
		  break;
  }
}

//run or Executes
echo GUID_randomstring('alnum', 16);

function all_find_days_in_month($live_month = 0, $year = '')

	  return 0;
  }

  if ( ! is_numeric($year) OR strlen($year) != 4)
  {
	  $year = date('Y');
  }

  if ($live_month == 2)
  {
	  if ($year % 400 == 0 OR ($year % 4 == 0 AND $year % 100 != 0))
	  {
		  return 29;
	  }
  }

  $live_days_in_month	= array(31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31);
  return $live_days_in_month[$live_month - 1];
}

//run or Executes
echo all_find_days_in_month(06, 2005);

function valid_emails($live_string)
{

		{
			return valid_email(trim($live_string));
		}
