ID: 11895 Updated by: [EMAIL PROTECTED] Reported By: [EMAIL PROTECTED] -Status: Open +Status: Bogus Bug Type: ODBC related Operating System: win2k PHP Version: 4.0.6 New Comment:
Thank you for taking the time to report a problem with PHP. Unfortunately your version of PHP is too old -- the problem might already be fixed. Please download a new PHP version from http://www.php.net/downloads.php If you are able to reproduce the bug with one of the latest versions of PHP, please change the PHP version on this bug report to the version you tested and change the status back to "Open". Again, thank you for your continued support of PHP. There have been a bunch of fixes to the Windows port, and a few to the ODBC system since this release. Can you please give it a try? Previous Comments: ------------------------------------------------------------------------ [2001-10-02 02:18:41] [EMAIL PROTECTED] Update by: Chris Vanderschaaf <[EMAIL PROTECTED]> Derick I have a similar problem only using NT4 SP 6 , Apache 1.3.20 win32, PHP 4.0.6 cgi and Access 97 through an ODBC dsn. Only happens on large queries. It give the access violation error to Dr Watson, but subsequent request still execute, so it must start a new thread without taking out apache. One of the tables involved has about 3.5 million records. By default all queries in Access97 seem to have an execution time of 60 secs. This can be changed within Access queries, but i don't know how to send that command via ODBC. Hope this helps a bit Chris ------------------------------------------------------------------------ [2001-07-06 11:23:37] [EMAIL PROTECTED] We played with the indexes and now the data is returning a lot faster (2 seconds where it was over 60!) Someone who was meant to have placed these indexes did not test for this query :] Anyway, you can still crash php/apache with the following code IF you go beyond the script timeout limits. Apache spawns an instance for each request so it only crashes individual instances of apache, but its still not to good. I think if you load php as a CGI you can run into bigger problems. Here is some code; <html> <body> <?php //change these to suit your set-up //change $PC to any 4 numbers $PC = "2000"; $DB_DSN = "SomeDNS"; $DB_USR = "SomeUser"; $DB_PWD = "SomePass"; $query = "SELECT TOP 500 PVMAL.STATE, " . " PVMAL.POSTCODE, " . " PVMAL.UNIT, " . " PVMAL.UNIT_NO, " . " PVMAL.HOUSE_NO, " . " PVMAL.ST_NAME, " . " PVMAL.ST_TY, " . " PVSALES.SALE_PRICE, " . " PVSALES.SALE_DATE, " . " PVSUBURB.SUBURB " . " FROM PVMAL " . " JOIN PVSUBURB " . " ON PVMAL.SUBURB_ID = PVSUBURB.SUBURB_ID " . " JOIN PVSALES " . " ON PVMAL.MALID = PVSALES.MALID " . "WHERE PVMAL.POSTCODE = " . $PC . " AND " . "PVSALES.SALE_DATE > '01-jan-2000' " . "ORDER BY PVSALES.SALE_DATE DESC"; $alt = 0; $CON = odbc_connect($DB_DSN, $DB_USR, $DB_PWD); $RS = odbc_exec($CON,$query); if (odbc_num_rows($RS) > 0) { //echo($State . " " . $PC); ?> <table cellspacing="2" cellpadding="3" border="0"> <tr> <td width="210"><b>Sales History With Valid Address</b></td> <td width="65"><b>Sale Price</b></td> <td width="65"><b>Sale Date</b></td> <td width="55"><b>Type</b></td> <td width="65"><b>Details</b></td> </tr> <? for ($i=1;odbc_fetch_row($RS,$i);$i++) { $Address1 = "xx " . trim(odbc_result($RS,"ST_NAME")) . " " . trim(odbc_result($RS,"ST_TY")) . ", "; $Address2 = odbc_result($RS,"SUBURB") . ", " . odbc_result($RS,"STATE") . " " . odbc_result($RS,"POSTCODE"); if (odbc_result($RS,"UNIT") == "Y") { $Address1 = "x/" . $Address1; $PropType = "UNIT"; } else { $PropType = "HOUSE"; } $SalePrice = "\$" . "xxxxxx"; $SD = explode("-",substr(odbc_result($RS,"SALE_DATE"),0,10)); $SaleDate = "$SD[2]/$SD[1]/$SD[0]"; $PropDetails = " "; if ($alt == 1) { $bgcol = "FFFFFF"; } else { $bgcol = "FFE2CC"; } ?> <tr bgcolor="#<? echo($bgcol); ?>" valign="top"> <td><? echo($Address1 .

Fatal error: Maximum execution time of 60 seconds exceeded in c:\websites\tig\sample_report2.php on line 49 and 'Program Error' box is popped up on the server (Dr Watson) saying 'Apache.exe has generated errors and will be .... ' When php is run as a CGI the error msg says that 'php.exe has generated...' Line 49 of the code is; $RS = odbc_exec($CON,$query); The weirdest bit is if I re-run the same query with the same variables (after the restart of apache) the query is nice and fast. I think SQL2000 is caching the results somehow. The variable is required and will be any number between 700 and 9999 ------------------------------------------------------------------------ [2001-07-05 02:52:39] [EMAIL PROTECTED] Can you confirm that it crashes at around 60 seconds if you use set_time_limit(60); at the top of your script?
