Show active navigation for current page with php

Question

I\'m trying to use use $current_url = basename($_SERVER[\'PHP_SELF\']); to determine which page I am on, considering my navigation (html) is stored in a php fil

Answer 1

You could also use preg_replace() to add class="active"

ob_start();
echo '

  
Page 1
  
Page 2
  
';
$output = ob_get_clean();
$pattern = '~
~';
$replacement = '
';
echo preg_replace($pattern, $replacement, $output);
