Here is another tutorial:

$languages = array('German', 'French', 'Spanish');
printf("

Languages: %s .

\n", implode(', ', $languages));

Here is another tutorial:

$countries_languages = array('Germany' => 'German', 'France' => 'French', 'Spain' => 'Spanish');
echo "Array values: ";
printf("

Languages: %s.

\n",implode(',', array_values($countries_languages)) );
echo "Array keys: ";
printf("

Countries: %s.

\n",implode(',', array_keys($countries_languages)) );

Here is yet another tutorial:

$customers = array(array('first' => 'Bill', 'last' =>'Jones', 'age' => 24, 'state' => 'CA'),
array('first' => 'Mary', 'last' => 'Smith', 'age' => 32, 'state' => 'OH'),
array('first' => 'Joyce', 'last' => 'Johnson', 'age' => 21, 'state' => 'TX'),
);

printf("print_r():

%s

", print_r($customers, TRUE));
printf("var_export():

%s

", var_export($customers, TRUE));

print 'var_dump():

';
var_dump($customers);
print '
