1.2.979. Possible Increment¶
This expression looks like a typo : a missing + would change the behavior.
The same pattern is not reported with -, as it is legit expression. + sign is usually understated, rather than explicit.
<?php
// could it be a ++$b ?
$a = +$b;
?>

1.2.979.1. Suggestions¶
Drop the whole assignation
Complete the addition with another value : $a = 1 + $b
Make this a ++ operator : ++$b
Make this a negative operator : -$b
Make the casting explicit : (int) $b
