proposal control-structures.for.php

Hi list,

could someone add a paragraph to the end of 'control-structures.for.php' that
it's not recommended to use count() in arg2 especially when the for loop is
used to unset elements of an array, because the function will be executed
every loop.

I mean:

for($i=0; $i<count($myarray); $i++)
...

instead:

$count = count(myarray);
for($i=0; $i<$count; $i++)
...

Best Regards,

Oliver
