php - how to use variable content as a part of a other variable name?

Solution:

This would be far better implemented using arrays.

e.g.

<?php
$vidoos = array(
  "fk16zv6mw2jj", 
  "eztx3n90w8xs",
  "eztx3n90w8xs",
  "eztx3n90w8xs",
  "eztx3n90w8xs",
  "eztx3n90w8xs",
  "eztx3n90w8xs",
  "eztx3n90w8xs",
  "eztx3n90w8xs",
  "eztx3n90w8xs"
);

$titlenumber = 0;
$vidoo="https://vidoo.tv/e/";

echo $vidoo.$vidoos[$titlenumber];

$titlenumber = 3;
echo "<br/>"; //line break, just for demo
echo $vidoo.$vidoos[$titlenumber];
?>
Copy code

Note that arrays start their indexes at 0 by default, so if you can start titlenumber at 0 too, you can do it simply like I've shown. If not, shift the array as shown in this answer

BTW you don't have to write a new<?php on every line. Just write it once at the start of the section of PHP, and close it once with?> at the end. Lines in between only need to end with;.
