Bug Report

Multiple concatenated variables (like "$prefix$main$suffix") are not recognized by the WrapEncapsedVariableInCurlyBracesRector rule.

Minimal PHP Code Causing Issue

The following code:

$prefix = '';
$main = '';
$suffix = '';
      
return "$prefix$main$suffix";

is changed to

$prefix = '';
$main = '';
$suffix = '';
      
return "{$prefix}$main{$suffix}";

Expected Behaviour

$prefix = '';
$main = '';
$suffix = '';

- return "{$prefix}$main{$suffix}";
+ return "{$prefix}{$main}{$suffix}";
