associative array in associative array

[Antoine Merieux]

Hi,
I'm trying to use associative array in another associative array

to feed it's ok
to retrieve, something's wrong
can you help me
thank you

<?php
session_start() ;
$tabItems = array(49, 59, 69, 79);
$tabExercice = array(
'1' =$tabItems,
'45' =$tabItems);

$tab = array(
'487' =$tabExercice,
'45' =$tabExercice,
'23' =$tabExercice);

$_SESSION['caddy'] = $tab;

//print_r($tab);

// Let see what is it
foreach ($tab as $k =$v) {
// the key is id_focus
echo "Liste des exercices pour le focus".$k;
foreach ($k as $k2 =$v2) {
// the key is id_exo
echo "<br>id_exo =".$k2;
echo "<br>liste des items";
for ($i=0; $i < count($v2); $i++)
{
echo $v2[$i]." ";
}
}
}

?>

Re: associative array in associative array

In your nested foreach, you're trying to loop over the key as opposed
to the nested array.

Change:
foreach ($k as $k2 =$v2) {
to:
foreach ($v as $k2 =$v2) {

In PHP4, arrays behave as if they only hold scalars in some regards (similar
to Perl) possibly in PHP5 too.

Try serializing the data before putting it in a session variable.
