I typed in $a = 5; just like it's shown in video. Why is the workspace telling me I have a syntax error?

I followed the video exactly but the workspace console is telling me I've done it wrong but I don't know what or why.

$a = 5; is correct PHP syntax. Can you share the rest of your code? Sometimes syntax errors are caused by other lines. Something like a missing ; or something

I was having the same problem. Below is the code I was using. I will use <<<< to point out my mistake and hopefully it can help anyone who might need it.

<?php $num_one = 1; $num_two = 2; $num_three = 3;

/var_dump( $num_one ); var_dump( 1 ); var_dump( "1" ); var_dump( $num_one + $num_two - $num_three );/

$distance_home = 1.2; $distance_work = 2.5;

var_dump($distance_home + $distance_work + $num_three + .3) <<<< I was missing ; at the end of this var_dump.

$a = 5; $b = 10;

var_dump($a * $b); var_dump($a / $b); ?>
