Plug-in concatenation Error

Description

In plugin-settings.php when a variable is concatenated in the format of:

<?php
$x = "Hello " . $i+1;

the result evaluates to $x = "1".

Haven't done full testing but these results turn out fine:

<?php
$x = $i+1."Hello";
$x = "Hello".1+$i;

Change History (1)

Hi @kaine78, welcome to WordPress Trac!

There's no plugin-settings.php file in WordPress core. The observed behavior is the result of PHP type casting due to the ​dot operator having the same precedence as + and -. I don't see a WordPress bug here.
