Passing 2 strings from one PHP script to the other using href -

i trying pass 2 strings first.php file second.php file-

in first.php file, tried send data

<?php echo "<a href='second.php?newformat=$statusstring&macaddress=$macaddress'>link</a>"; ?> 

and

<a href="second.php?newformat="<?php echo $statusstring; ?> &macaddress=<?php echo $macaddress; ?>link</a> 

and

<a href="second.php?newformat=<?php echo urlencode($statusstring);?>&amp;macaddress=<?php echo urlencode($macaddres); ?>"link</a> 

i tried of above possibilities. same error -

php parse error: syntax error, unexpected '<' in /var/www/html/first.php on line 176

my $statusstring - "u=500000;t1=1479394;s=10;r=-33;v=3.7;"

my $macaddres - "500000"

can tell me how differently do this?

edit 1

i have tried comment line in code, , code works without errors!

edit 2

if(some condition) {         $statusstring = "u=".$macaddress.";t1=".$time.";s=10;r=-33;v=".$voltage.";";     <?php echo "<a href='second.php?newformat=$statusstring&macaddress=$macaddress'>link</a>"; ?> } 

in second.php file, retrieving these by-

if (isset($_get['newformat'])) {      $str = $_get['newformat']; } else      $str = 'no data';  if (isset($_get['macaddress']))  {      $macaddress = $_get['macaddress'];  } 

in last edit:

if(some condition) {        $statusstring = "u=".$macaddress.";t1=".$time.";s=10;r=-33;v=".$voltage.";";     <?php echo "<a href='second.php?newformat=$statusstring&macaddress=$macaddress'>link</a>"; ?> } 

well, explains unexpected <. you're already in context of php code. can write php code:

if(some condition) {        $statusstring = "u=".$macaddress.";t1=".$time.";s=10;r=-33;v=".$voltage.";";     echo "<a href='second.php?newformat=$statusstring&macaddress=$macaddress'>link</a>"; } 

no need sprinkle in more <?php ?> tags, you're confusing php parser.

edit: should url-encode values, since complex:

echo '<a href="second.php?newformat=' . urlencode($statusstring) . '&macaddress=' . urlencode($macaddress) . '">link</a>';
