Previous Comments: ------------------------------------------------------------------------ [2004-08-09 12:44:38] wez@php.net Crash or exception? Paste the output you see from the CLI here please. ------------------------------------------------------------------------ [2004-08-09 11:54:27] edwin at rabbito dot org Description: ------------ When trying to retrieve a date field from an Access 97 database, the actual data returned is different from PHP4 (PHP 4 returns a timestamp, whereas PHP 5 returns a date, ie) 02/04/04 instead of a timestamp). By calling the code (as attached) in PHP5, PHP does not return error gracefully, but crashes. (seems to be something that is not yet fixed in bug#29392) Reproduce code: --------------- $security="C:\access97.mdw"; $user="access"; $password="access"; $dsn="Driver={Microsoft Access Driver (*.mdb)}; DBQ=$database;SystemDB=$security;Uid=$user;Pwd=$password"; $db = new COM("ADODB.Connection"); $db->open($dsn); $query="SELECT DateField1 FROM [Table1];"; $rs = $db->execute($query); if (!$rs->EOF()) { echo strlen($rs->Fields(0)->Value); } Expected result: ---------------- Either an error should be returned due to invalid type ($rs->Fields(0)->Value in date type), or the actual length the the date string. Actual result: -------------- PHP crashed ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=29583&edit=1
