PHP - what's wrong with this piece of code? - 


<?  function foo($return = false) {     $x = '12345';      $return ?     return $x : // here fails     echo $x; }  echo foo(true);  ?>

it says "parse error: syntax error, unexpected 'return' (t_return) in..."

why!? :)

you can't use inline ifs in way. used this:

echo ($return ? x : "false");

your code should this:

<?  function foo($return = false) {     $x = '12345';      if($return)     {         return $x     }     else     {         echo $x;     } }  echo foo(true);  ?>

(more confusing some), don't need add else statement, if if statement satisfied, return value, exiting function, means if if statement not satisfied, go echo anyway:

<?  function foo($return = false) {     $x = '12345';      if($return)     {         return $x     }     echo $x; }  echo foo(true);  ?>
