Array to string conversion array it happens no matter how I echo
// with single quotes on inner key
echo "<li>$contacts[0]['name'] : $contacts[0]['email']</li>\n";
// without single quotes on inner key

// desperation
print_r "<li>$contacts[2]['name'] : $contacts[2]['email']</li>\n";

// meaning each person in the contact list will have their own array. The first step is to make each person
// their own single item ASSOCIATIVE array, using 'name' as the key for these internal arrays.
//edit this array
