there have errors the form correct to do that is of this way:

 function gen() {
    echo "Foo\n";
    try {
    
    throw new Exception('Prueba');

    } catch (Exception $e) {
        echo "Excepción: {$e->getMessage()}\n";
    }
    echo "Bar\n";
}

 gen();

 i resolved one tecnic of how work getMessage look at it:

$myarray=array();

if($respuesta == "Mark"){

for($i=5;$i<=16;$i++){
try {

    $palabra="soy la excepcion en la linea:".$i;

     throw new Exception($palabra);

}
catch(Exception $e) {
 
        $myarray[$e->getLine()] =$palabra;
       
        if($e->getLine() == $i){
  echo "<br><b>La excepción se creó en la línea : " .$e->getLine()."LA LINEA DICE:". $myarray[$e->getLine()]."</b>";
}//if

}//catch
   

}//for

}//if
