#15479 [Opn->Csd]: problem referencing $_GET using a variable

ID: 15479 Updated by: sniper@php.net Reported By: pguillot@paanjaru.com -Status: Open +Status: Closed Bug Type: Documentation problem Operating System: Linux PHP Version: 4.1.1 New Comment: Documented here: http://www.php.net/manual/en/language.variables.variable.php Previous Comments: ------------------------------------------------------------------------ [2002-07-02 17:24:25] sniper@php.net reclassified. (not bug but documentation issue) ------------------------------------------------------------------------ [2002-02-09 18:30:05] pguillot@paanjaru.com It seems that it is not possible to reference the $_GET, $_POST, etc using a variable as in (A) : $var_get = '_GET'; $local_get = $$var_get; $var_http_get = 'HTTP_GET_VARS'; $local_http_get = $$var_http_get; Now if the requested url contains &something=12 print $local_http_get['something'] . '*'; // print the string '12*' print $local_get['something'] . '*'; // print the string '*' But if (B) : $local_good=&$_GET; $var_good = 'local_good'; $var_get = $$var_good; print $local_get['something'] . '*'; // print the string '12*' Would it be a problem trying to reference a variable which name starts with an underscore ? I use this kind of syntax to check if something not allowed exists in the url, using an array like $to_check = array( '_GET', '_POST' ); Anyway, as it's possible to use an alternative syntax (B), it is not a __big__ problem, after all ! Keep on with a so nice job, I am still amazed about the power and speed of Php, after more than 2 years using it, in a production environment. Thanks a lot, and have a nice day. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=15479&edit=1
