Add 1 to value not working

[liamloveslearning]

Hi all, im trying to call a number from a db, add 1 to it and then print it to the browser,

 

I've been googling to no avail and ive been trying playing about, guesswork basically.

 

At the moment im left with

<?php $jobby = $row_gethighestworld['intrajobno']; 
            $nxtjob = ('+1' . $jobby);
           echo $nxtjob; ?>

Just tried this to no avail!

 

<?php
$c = $row_gethighestworld['intrajobno']; 
$d= $c + 1 ;
echo $d; 
?>

okay finally got it working using

<?php $newno = $row_gethighestworld['intrajobno'] += 1; echo $newno; ?>

 

only now all instances of $row_gethighestworld['intrajobno'] are showing the value +1. I need just 1 instance of this to make the addition, it needs to be a unique variable if this makes sense?

sorted! <?php $newno = $row_gethighestworld['intrajobno'] + 1; echo $newno; ?>
