			$str_alpha_up = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
			$str_alpha_small = "abcdefghijklmnopqrstuvwxyz";
			$str_num = "1234567890";
			$str_sym = "~!@#$%^&*()_'-\=+[];:<>,\/.?|";
			$str = $str_alpha_up.$str_alpha_small.$str_num.$str_sym;
			$str_len = strlen($str) - 1;
			$pwd_str = '';
			$pwd_len = 0;
			while ($pwd_len < $length) {
				$n = rand(0, $str_len);
				$pwd_str .= $str[$n];
				$pwd_len = strlen($pwd_str);
			}
			return htmlentities($pwd_str);
		} else {
			return false;
		}

$pass = password_generate_method1(10); 
echo "<p> password $pass </p>";

			$string .= "~!@#$%^&*()_'-\=+[];:<>,\/.?|";
			$shuffle = str_shuffle($string);
			$pwd_str = substr($shuffle, 0, $length);
			return htmlentities($pwd_str);

$pass = password_generate_method3(10); 
echo "<p> password $pass </p>"; 

Method 4

	//Using Array

			$string .= "~!@#$%^&*()_'-\=+[];:<>,\/.?|";
			$str_arr = str_split($string, 1);
			$shuffle = shuffle_assoc($str_arr);
			$pwd_str = implode("",array_slice($shuffle,0,$length));
         return $pwd_str;
		} else {
