• How to set an option from multiple options or array with different values to views as selected in select box using PHP 2 answers

This is my php code.

 $list .="<option value='$A $B'> $A,$B </option>";

I want to put a select option based on data. for example if $A = 1 and $B =2 then the option value get selected.

Normaly I would do it through this code

<?php echo $A == '1' ? 'selected' : ''; ?>

Option 2:

$selected = $A == '1' ? 'selected : '';
$list .="<option value='$A $B' $selected> $A,$B </option>";
