Two variables in echo PHP -

i have loop , want show values question$vari2 in loop

            $vari1=$_session['quantity'];             $vari2=0;             while($vari2<$vari1){                 $vari2++;                 extract( $_post, extr_overwrite, "question$vari2" );                 echo "<br>data1= ".$_session['data1'.$vari2];                 echo "<br>data2= ".$_session['data2'.$vari2];                 echo "<br>data3= "."$question1"."<br>"; //problem line             } 

how write last line show question1, question2 ... in loop try echo '$'.'question'.$vari2; show $question2 in file not values of variable

you looking variables variable:

$var = "question{$vari2}"; echo "<br>data3={$$var}<br>";
