在Codeigniter视图中使用变量作为数组名称

I passed $data array to view. $data array is like:

$data = array('t0' => array('point' => 0), 't1' => array('point' => 2) .... );

What I am trying to do is using this array in my view as follows:

<?php echo $t0['point']; ?> //It works!

But I am doing this in a for loop by definition of structure. Therefore I need to pass numeric value(near 't' letter) as a variable. How can I achieve this?

you can do like this:

$count = count($data);   //if you know the count of $data
 for($i = 0; $i < $count; $i++) {
        $var = 't'.$i;
        echo ${$var}['point'];
    }

You'll need to send through a count in your data, so you can later run a loop, so change your $data array to something like:

$data = array('tCount' => 10, 't0' => array('point' => 0), 't1' => array('point' => 2) .... );

Note the addition of the tCount variable in the array, that should tell how many t items you are sending in the array, we'll use that in the loop below.

Now you can use a variable variable, something like:

foreach ($i = 0; $i < $tCount); $i++) {
    $key = 't' . $i;
    echo($$key['point']);
}

Note the use of the double $

If you are using it in a for loop and your changing variable is $x, you could use:

<?php echo $data['t'.$x]['point']; ?>

So, you could do something like:

$data = array('t0' => array('point' => 0), 't1' => array('point' => 2) .... );
for ($x = 0; $x < count($data); $x++) {
    echo $data['t'.$x]['point'];
}
