note 86475 added to function.get-defined-vars

As a note, get_defined_vars() does not return a set of variable references (as I hoped). For example: <?php // define a variable $my_var = "foo"; // get our list of defined variables $defined_vars = get_defined_vars(); // now try to change the value through the returned array $defined_vars["my_var"] = "bar"; echo $my_var, "\n"; ?> will output "foo" (the original value). It'd be nice if get_defined_vars() had an optional argument to make them references, but I imagine its a rather specialized request. You can do it yourself (less conveniently) with something like: <?php $defined_vars = array(); $var_names = array_keys(get_defined_vars()); foreach ($var_names as $var_name) { $defined_vars[$var_name] =& $$var_name; } ?> ---- Server IP: 209.41.74.194 Probable Submitter: 208.101.181.19 ---- Manual Page -- http://www.php.net/manual/en/function.get-defined-vars.php Edit -- https://master.php.net/note/edit/86475 Del: integrated -- https://master.php.net/note/delete/86475/integrated Del: useless -- https://master.php.net/note/delete/86475/useless Del: bad code -- https://master.php.net/note/delete/86475/bad+code Del: spam -- https://master.php.net/note/delete/86475/spam Del: non-english -- https://master.php.net/note/delete/86475/non-english Del: in docs -- https://master.php.net/note/delete/86475/in+docs Del: other reasons-- https://master.php.net/note/delete/86475 Reject -- https://master.php.net/note/reject/86475 Search -- https://master.php.net/manage/user-notes.php
