I am trying to make a variable addition code like this

Code: Select all

$addedvalue = 5;

$mysqlvalue + $addedvalue = $totalvalue;

print($totalvalue);
totalvalue has been displaying as 0. It should not display as 0.

anyone know how to fix this

Code: Select all

$totalvalue = $mysqlvalue + $addedvalue
Assignment always works in the order that whatever's on the left of the assignment operator (=) is given the value of whatever's on the right of it.

ok but now its counting like this

19 = 0 + 10

the result should be 10
