I want you to click on the hyperlink for the second time to execute another code.

<a href=?ordem=nom>$lib_nom</a>


//ordena dados do array ASC
array_multisort( $affiche_ord, SORT_ASC, $affiche_tab );

//ordena dados do array DESC
array_multisort( $affiche_ord, SORT_DESC, $affiche_tab );

If you click once make the ASC if it is the second time DESC, and so on.

php

You can do this by switching between one parameter and another by capturing the variable ordem with $_GET and applying to the function according to the parameter sent by the link:

<?php
$ordem = $_GET['ordem'];
$nova_ordem = empty($ordem) || $ordem == 'SORT_DESC' ? 'SORT_ASC' : 'SORT_DESC';

echo '<a href="?ordem='.$nova_ordem.'">$lib_nom</a>';

array_multisort( $affiche_ord, $ordem, $affiche_tab );
?>

If the ordem parameter is empty, the ?ordem=SORT_ASC value will be included in the link, and then it will alternate with ?ordem=SORT_DESC as the link is clicked.
