#17290 [Com]: Cannot use [] for reading

ID: 17290 Comment by: 7l9it46r1adm1l1 at jetable dot com Reported By: mellow at mellow dot dk Status: No Feedback Bug Type: Scripting Engine problem Operating System: Linux PHP Version: 4.1.2 New Comment: I got the same strange Fatal error (using Windows XP, PHP PHP 5.0.4): Fatal error: Cannot use [] for reading in ... on line 82 [php] if ($insert->check($_POST['value']) === FALSE) { $error[] == 'Error'; // line 82 } [/php] Zend Developer didn't give any warnings so there shouldn't be any syntax mistakse in that PHP file.

Probably there is a major bug in the parser (priority?), because the workaround with $array[{$array_b[1][2]}], which I would expect that first {$array_b[1][2]} is evaluated and then $array[$evaluation_result] gets the error that no {} are allowed. I am not sure this is a new bug, but I remember in 4.0.x it always worked fine. ------------------------------------------------------------------------ [2002-05-17 11:02:29] mellow at mellow dot dk I've build an array using the following in a function : ------------- $this->get_data(array("","","and D.XiParentId= 'gwak_root_element' ORDER BY D.vcOrder")); $arrCategory = $this->return_array(); for($i = 0 ; $i < sizeof($arrCategory) ; $i++) { $this->get_data(array("","","and D.XiParentId = '" . $arrCategory[$i]["XiDataId"] . "' ORDER BY D.vcOrder")); $arrItem[$arrCategory[$i]["vcItemId"]] = $this->return_array(); } return $arrItem; ------------- This constructs an array with values like : $arrItem["project_priority"][0] = array(...) $arrItem["project_priority"][1] = array(...) etc... Later I tried to do the following to the returned $arrItem : ------------- $arrItem["project_severity"][] = array("XiDataId" => "gwak_get_all", "vcText" => "All"); ------------- This gives the error : ------------- Fatal error: Cannot use [] for reading in /home/plb/public_html/gwak/module/project/include/Task.class.php on line 160 ------------- Funny because doing the following : ------------- $arrThis["here"][] = array("XiDataId" => "asdasdas", "vcText" => "324234234"); $arrThis["here"][] = array("XiDataId" => "asdasdas", "vcText" => "324234234"); $arrThis["here"][] = array("tr" => "ert"); $arrThis["where"][] = array("er" => "ert"); $arrThis["where"][] = array("we" => "ert"); $arrThis["where"][] = array("tr" => "ert"); ------------- gives no error at all, eventhough $arrThis and $arrItem have exactly the same format. Do you guys have an idea what is going on here? The only thing i can see could cause the problem is that $arrItem is built using "arrays within arrays": $arrItem[$arrCategory[$i]["vcItemId"]] = array(...); Can this be the cause or... In advance thx... ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=17290&edit=1
