Generator::throw — Throw an exception into the generator
Descrizione
Throws an exception into the generator and resumes execution of the generator.
The behavior will be the same as if the current yield expression was replaced with
a throw $exception statement.
If the generator is already closed when this method is invoked, the exception will be thrown in the caller's context instead.

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
