Adding with a string as an integer...

[Anon]

Hi, I just want to know simple thing..
how do I add a string + 3....

like
$num = 4;
echo "$num + 3"
and I want the output to be 7...do you get what I mean?

Sorry for my newbie questions 😛
Thanks..

Why not just do:
echo $num + 3;
?

try
$num = 4;
$result=$num+3;
echo $result;

...or just
$num = 4;
$num += 3;
echo $num; // will output 7

That's all good...but is there a way to do it within an echo statement?

for instance:

$num = 5;
echo "The number is ($num) and the number plus 3 is ($num+3)";
// where $num+3 equals 8

I hope you see what I mean..

Thanks..

Read Diego Huang's reply.

$num = 5;
echo "The number is ($num) and the number plus 3 is (".$num+3.")";

Humm, still no luck..I tried the last one and it gave me Parse error: parse error, expecting ','' or';'' in c:\foxserv\www\num.php on line 3
<?
$num = 5;
echo "The number is ($num) and the number plus 3 is (".$num+3.")";
?>

Any Idea?

Y'see, at this point I'd've looked at the manual again and saved everyone's time.

<?
$num = 5;
echo "The number is ($num) and the number plus 3 is (".($num+3).")";
?>
