There is "." to concatenate the first and the second lines. So, echo 'A'. b='B'; == echo 'A'.b='B'; == echo 'AB';

echo 'A'. $b = 'B'; echo 'B'; echo 'C'; Answer: ABBC because of dot (.) echo 'A'; $b = 'B'; echo 'B'; echo 'C'; Answer: ABC

There's a dot (.) between first and second line which concatenates AB and the rest is same.

AJ #L1G3 both of these are the same... <?php echo 'A'. /* did you see the period */ $b = 'B'; echo 'B'; echo 'C'; ?> <?='A'.$b='B'.'B'.'C';?>

Vladimir Got it. If there is semicolon then answer will be ABC. Right?

AJ #L1G3 It's in the dot (.) and semicolon (;). Many viable answers here already... 👌
