Shorten php for the last letter

You want the substrign of that value, less one. See https://www.php.net/manual/en/function.substr.php

Thank you but I dont know how to put it in a correct way with my <?php echo pods_field_display( 'voe_kategorie' );?>

Sorry ??

<?php
$pfd = pods_field_display( 'voe_kategorie' );
$pfdlen = strlen($pfd);
echo substr( $pfd, 0, $pdflen-1);
?>

Perfect ! Many thanks !
