Php Sytax Help.

Dear, I'm Trying tO Write A Syntax In Php, But I Can't,
Look,
$Page1 = '13';
I'm Trying tO Write It In This Format,
$Page = '10';
$Page1 = '$Page+3';
But Error Accoutred, Please Solve It ..

 

$Page1= $Page + '3';

 

ThaNks Dear ..

 

you could also leave $Page1 = 13;
without making it a string and leaving it an integer.

 

Ummm, ThaNks ..

 

well you are using it as a string '13'
Math and Logic in PHP are different. sometimes you can get away with it, but once you get used to it, you'll be reminded along the way when certain functions wont see string as integer
