PHP Code:

$rank = $site->user->rank; 

 

while( list($key, $value) = each($rank) ) 

     $extra += "boob   ";//" OR LIKE %".$value."%"; 

 

echo $extra; 

if i echo $value in the while loop it outputs values
but with $extra it will output nothing



Thanks in advance

Because you're doing it wrong, you don't use + to add on to a string, this isn't javascript

PHP Code:

$extra .= 'boob        '; 

You use . to append in PHP.

Another example:

$a = 3;
$a += 5; // sets $a to 8, as if we had said: $a = $a + 5;
$b = "Hello ";
$b .= "There!"; // sets $b to "Hello There!", just like $b = $b . "There!";
