PHP: How to echo strings from an Array? -

i'm stuck trying echo strings array, "array" text.

this array:

    $_session['lista'][] = array( 'articulo' => $articulo,  'precio' => $precio,  'cantidad' => $cantidad); 

this echo:

echo "1. ".$_session['lista'][0][0]." ".$_session['lista'][0][1]." unidades".", ".$_session['lista'][0][2]." crc."; 

the current output is:

1. array array unidades, array crc. 

remove [] looks these , put session_start() @ starting line;

<?php session_start(); $_session['lista'] = array( 'articulo' => $articulo,  'precio' => $precio,  'cantidad' => $cantidad); ?> 

to access array:

echo $_session['lista']['articulo'];  echo $_session['lista']['precio'];
