Are these actual program snippets? If they are then
(1) '$test1 = array()' line is missing a trailing ';'
(2) The statement 'list($test,$test1);', to the best of my knowledge,
does nothing in this context.
(3) From your echo statement, you should see the output
'list(Array,Array)' - functions and language constructs aren't
evaluated in double-quoted strings; only variables.
It would make more sense to me to have something like
$test = array('bean', 'noodle', 'wednesday');
$test1 = array('a'=>'apple', 'b'=>'banana', 'c'=>'carrot');
$foo = array($test, $test1);
Then you could display these values like so:
If you have PHP4, use print_r() or var_dump():
echo print_r($foo);
See
http://www.php.net/manual/en/function.print-r.php
http://www.php.net/manual/en/function.var-dump.php
I haven't used either of these functions, so I don't know exactly
what the output looks like. It says var_dump() was available in PHP 3
after 3.0.5, but I'm not entirely sure that's true. If it is, it must
have been undocumented for a while.
An alternative display method would be something like (a little more
cumbersome, but works in PHP3 & 4):
for ($i=0; $i<count($foo); $i++)
{
while(list($Key,$Val) = each($foo[$i]))
{
echo "foo[$i][$Key] = $Val<br>\n";
}
}
Also, instead of the
$test = array('bean', 'noodle', 'wednesday');
$test1 = array('a'=>'apple', 'b'=>'banana', 'c'=>'carrot');
$foo = array($test, $test1);
way of declaring the $foo array, you could also say
$foo = array(
array('bean', 'noodle', 'wednesday'),
array('a'=>'apple', 'b'=>'banana', 'c'=>'carrot')
)
or
$foo[0] = array('bean', 'noodle', 'wednesday');
$foo[1] = array('a'=>'apple', 'b'=>'banana', 'c'=>'carrot');
