在Codeigniter视图中使用变量作为数组名称

Question

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?

Answer 1

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'];
    }
