From manual page: http://www.php.net/control-structures.while

According to the documentation(and many old comments), having a space between the while keyword and the expression is legal. This seems to no longer be the case, so a direct use of the while loop example would not work with a recent build of PHP.
Documented-
while (expr):
    statement
    ...
endwhile;

Functional-
while(expr):
    statement
    ...
endwhile;
