If the $name constant doesn't exist in the targetted class the function returns bool(false), not empty nor null but false (you to test with "==="

$constFounded = false ;
$this->currentlangClass = new ReflectionClass($langFile);
$this->currentlangClass->getConstant($constant);
if($myConst !== false){
              $constFounded = true ;
}

The "getconstant" method can be used to get the value associated with a constant
of a particular class that you are examining.
The following code snippet shows this:

<?php
   
class Test{
        const
ONE = "Number one";
        const
TWO = "Number two";
    }
   
   
$obj = new ReflectionClass( "Test" );
    echo
$obj->getconstant( "ONE" )."\n";
    echo
$obj->getconstant( "TWO" )."\n";
   
?>

output:
Number one
Number two
