Question

I have following problem. I have file variable.php with declared variable:

<?php
  $animal = "cat";
?>

And file b.php, where I want to use this variable in a function

<?php
  include_once 'a.php';

  function section()
  {
     $html = "<b>" . $animal "</b>";
     return $html;
  }
?>

and file c.php where I’m using my function section()

<?php
  require_once 'b.php';
  echo section();
?>

I have an error message, that variable $animal does not exist in file b.php. Why and what can I do here?

Best regards,
Dagna

Answer 1

send $animal; to the function:

function section($animal)
  {
     $html = "<b>" . $animal "</b>";
     return $html;
  }
