#27572 [Opn->WFx]: Allowing characters other than [] to define arrays in POST or GET variables

ID: 27572 Updated by: derick@php.net Reported By: marwan at marvonline dot org -Status: Open +Status: Wont fix Bug Type: Feature/Change Request Operating System: Any PHP Version: Irrelevant New Comment: We use the [] everywhere for array accesses, we can't change it because it will break a lot of scripts, and by making it a switch you prevent people from writing portable scripts. Previous Comments: ------------------------------------------------------------------------ [2004-03-11 12:05:30] marwan at marvonline dot org Description: ------------ PHP registers HTML variables that look like arrays as array variables, which is pretty convenient for packaging form variables. I'm building a form generator that utilizes this feature a lot. It uses it something like this: for ($i=0; $i<count($data['ID']); $i++) { echo "<input type=\"hidden\" name=\"data[ID][$i]\" value=\"{$data['ID'][$i]}\"> " ."<input type=\"text\" name=\"data[Name][$i]\" value=\"{$data['Name'][$i]\"><br>\n"; } The (slightly) annoying thing about this is that urlencoding the variable names replaces the '[' and ']' with three letter codes. If the arrays are large (as they typically are) this bloats the POST request quite a lot. If PHP would consider the '.' as an array operator when registering GET and POST variables, it would improve matters. The '.' is urlencoded as a '.' with no charcter inflation. Further, it would only require one operator instead of two ([ and ]). The code would then look like: for ($i=0; $i<count($data['ID']); $i++) { echo "<input type=\"hidden\" name=\"data.ID.$i\" value=\"{$data['ID'][$i]}\"> " ."<input type=\"text\" name=\"data.Name.$i\" value=\"{$data['Name'][$i]\"><br>\n"; } Since PHP forbids using the '.' in variable names anyway, this shouldn't affect much code. To be safe, an INI option could be made to switch this behaviour on and off. As far as I can tell, the only function that would need to change would be php_register_variable_ex in main/php_variables.c I would be quite willing to re-code the function and hand it to someone who has CVS access. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=27572&edit=1
