在base_url（）的参数内部回显

Question

I have this code below:

href="<?= base_url('classes/number_of_class')?>"

I'm thinking of something like this

href="<?= base_url('classes/$class['number']')?>"

I don't have any idea how to multi quote this or if it is even possible. Any other way how to do this is welcome.

Answer 1

Try this

<?= base_url("classes/{$class['number']}")?>

Or this

<?= base_url("classes/" . $class['number'])?>

Answer 2

尝试这个，

href="<?= base_url('classes/'.$class['number'])?>"
