note 24341 added to language.variables.variable

Here's a simple example that writes a hidden form field when passed the variable name. function print_hidden($el){ GLOBAL ${$el}; echo("<input type=hidden name=$el value='" . ${$el} . "'>"); } so... print_hidden('id'); will store the value of $id in a hidden form field. Same as typing: <input type=hidden name=id value='$id'> -- http://www.php.net/manual/en/language.variables.variable.php http://master.php.net/manage/user-notes.php?action=edit+24341 http://master.php.net/manage/user-notes.php?action=delete+24341 http://master.php.net/manage/user-notes.php?action=reject+24341
