Echoing an abstract variable in PHP

Question

So I have some code that looks like this

<tr>
 <td>
  <?php echo "text_". $textnum ?>
 </td>
</tr>   

And I want the code to function the same as

<tr>
 <td>
  <?php echo $text_x ?>
 </td>
</tr>  

Where X is the value of $textnum. I cannot just use <?php echo $text_1?> because I dont know which text variable i am going to be echoing

Answer 1

Use <?=${'text_'.$textnum};?> or <?php echo ${'text_'.$textnum}?>
