### CODE ###
$Flag = 0;
if ( $Flag == 'N' ) echo "1";
else echo "2";
### END ###
Result: 1

If the $Flag is integer value and 'N' non integer, why this operation gives true as the result?
This is different types 0 and 'N', but if the programm can compare this values, it will be better to give "false"!

Can you explane this ?

Use === for exact comparison. == is 'numeric' comparison.
