I don't get seven when I type $a++;

treehouse:~/workspace$ php numbers.php
PHP Parse error: syntax error, unexpected ';' in /home/treehouse/workspace/numbers.php on line 24

Parse error: syntax error, unexpected ';' in /home/treehouse/workspace/numbers.php on line 24

My code was:

$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);

$a = 5;
$b = 10;

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

$a = $a + 1;

I got caught out by this as well. It would have helped if Alena Holligan had shown the duplicated line on screen below the increment line.

yes i think if she had shown how she duplicated it would be easier

Try one of them:


$a += 1;


$a = $a + 1;

But the problem maybe is that, You write the last value giver "$a++" after the "var_dump($a)", so the var_dump still contains the upper value of the $a.

I hope I can You!

this got me too - should have scrolled down to show we insert $a++ in between
