On fgets() document is write

string fgets ( int fp [, int length])

bug is you just write php code like

$string = fget($fp);

it will print out some warn info about "Wrong parameter count".

when I check the source code on fgets(), it writed
if (ARG_COUNT(ht) != 2 || zend_get_parameters_ex(2, &arg1, &arg2) == FAILURE) {
   WRONG_PARAM_COUNT;
}

I think it must not ARG_COUNT(ht) != 2
