Hello ,

I have a table like $data[$var][$i] $data is an string, $var is a string and $i is an index int.

I am tired to write for($i=1;,$i<=count($$data[$var],$i++) { echo $data['id'][$i] ... }oouuuff

How i can make it with foreach ?

I tried foreach ($data -> $field as $value) echo $value; but i doesnt work.

Any advise ?

Okay, so there's no key to call on, therefore I'm assuming you want to loop through them all.  What I don't understand is why you would use an array within an array making the inner array the first item of the outer array, which is pointless unless there's multiple arrays in it.

 

A more sensible array would be something like:

 

$data = array(
    'key1' => array(1, 2, 3),
    'key2' => array(1, 2, 3),
    'key3' => array(1, 2, 3)
);

 

Then you could call on it by the key of choice (as it looks like you were trying to do by the previous posts).

 

$data = array(
    'key1' => array(1, 2, 3),
    'key2' => array(4, 5, 6),
    'key3' => array(7, 8, 9)
);

$var = 'key2';

foreach ($data[$var] as $item)
{
    echo "{$item}<br />";
}

 

Outputs

 

4
5
6

 

Hopefully I'm correct on what you're trying to do.
