Hi,

I have a link in my web page and when user click on this link, i would like
to execute a PHP function with a parameter.
how can i do it ?

ex :
<?php
function lang($language)
{
  $lg = $language;
}
?>

...

<A href="<?php lang("eng");?>">test</A>

but this does not work.... :-(
thanks for help.
