I encounter a problem every time I do an odbc_prepare or odbc_exec call. The function call works fine and the correct results are generated (and displayed if I do an odbc_result_all), but the output from php hangs once all of the page has been output - ie the browser still thinks that there is more to come. The system log in the event viewer shows an error, source WAM, description The HTTP server encountered an unhandled exception while processing the ISAPI Application 'C:\WINNT\system32\php4isapi.dll'. Here's a simple page that causes the error (as a data source I'm using the adventureworks database which comes with the IIS for use with an ASP example): <html> <head></head> <body> <?php $a=odbc_connect("Adventure","",""); /*always returns 1 (NB I've tried this with sundry cursor types but with no change in behaviour)*/ if(!$a) { print("failed connecting"); exit(); } $test=odbc_exec($a,"select ShipDate from Orders where ShipCity='Anchorage'"); /*always returns 2*/ if(!$test) { printf("failed in exec"); odbc_close($a); exit(); } $closed=odbc_close($a);/*always returns 0*/ ?> </body> </html> Note that the above script works perfectly on php 3.0.11 running on the same machine. If it helps, here's the output of the ODBC trace: inetinfo 119:11f ENTER SQLAllocEnv HENV * 0x002b4890 inetinfo 119:11f EXIT SQLAllocEnv with return code 0 (SQL_SUCCESS) HENV * 0x002b4890 ( 0x05801500) inetinfo 119:11f ENTER SQLAllocConnect HENV 0x05801500 HDBC * 0x002b4894 inetinfo 119:11f EXIT SQLAllocConnect with return code 0 (SQL_SUCCESS) HENV 0x05801500 HDBC * 0x002b4894 ( 0x058022e0) inetinfo 119:11f ENTER SQLConnectW HDBC 0x058022e0 WCHAR * 0x058016b0 [ -3] "Adventure\ 0" SWORD -3 WCHAR * 0x1f4be05c [ -3] "******\ 0" SWORD -3 WCHAR * 0x1f4be05c [ -3] "******\ 0" SWORD -3 inetinfo 119:11f EXIT SQLConnectW with return code 0 (SQL_SUCCESS) HDBC 0x058022e0 WCHAR * 0x058016b0 [ -3] "Adventure\ 0" SWORD -3 WCHAR * 0x1f4be05c [ -3] "******\ 0" SWORD -3 WCHAR * 0x1f4be05c [ -3] "******\ 0" SWORD -3 inetinfo 119:11f ENTER SQLAllocStmt HDBC 0x058022e0 HSTMT * 0x002b59e0 inetinfo 119:11f EXIT SQLAllocStmt with return code 0 (SQL_SUCCESS) HDBC 0x058022e0 HSTMT * 0x002b59e0 ( 0x05802520) inetinfo 119:11f ENTER SQLGetInfoW HDBC 0x058022e0 UWORD 8 <SQL_FETCH_DIRECTION> PTR 0x00f3fa74 SWORD 4 SWORD * 0x00f3fa5a inetinfo 119:11f EXIT SQLGetInfoW with return code 0 (SQL_SUCCESS) HDBC 0x058022e0 UWORD 8 <SQL_FETCH_DIRECTION> PTR 0x00f3fa74 SWORD 4 SWORD * 0x00f3fa5a (4) inetinfo 119:11f ENTER SQLSetStmtOption HSTMT 0x05802520 UWORD 6 <SQL_CURSOR_TYPE> UDWORD 2 inetinfo 119:11f EXIT SQLSetStmtOption with return code 1 (SQL_SUCCESS_WITH_INFO) HSTMT 0x05802520 UWORD 6 <SQL_CURSOR_TYPE> UDWORD 2 DIAG [01S02] [Microsoft][ODBC Microsoft Access Driver]Option value changed (10) inetinfo 119:11f ENTER SQLExecDirect HSTMT 0x05802520 UCHAR * 0x0029f7e0 [ -3] "select ShipDate from Orders where ShipCity='Anchorage'\ 0" SDWORD -3 inetinfo 119:11f EXIT SQLExecDirect with return code 0 (SQL_SUCCESS) HSTMT 0x05802520 UCHAR * 0x0029f7e0 [ -3] "select ShipDate from Orders where ShipCity='Anchorage'\ 0" SDWORD -3 inetinfo 119:11f ENTER SQLNumResultCols HSTMT 0x05802520 SWORD * 0x002b59e8 inetinfo 119:11f EXIT SQLNumResultCols with return code 0 (SQL_SUCCESS) HSTMT 0x05802520 SWORD * 0x002b59e8 (1) inetinfo 119:11f ENTER SQLColAttributes HSTMT 0x05802520 UWORD 1 UWORD 1 <SQL_COLUMN_NAME> PTR 0x002a68b0 SWORD 32 SWORD * 0x00f3fa4e SDWORD * 0x00000000 inetinfo 119:11f EXIT SQLColAttributes with return code 0 (SQL_SUCCESS) HSTMT 0x05802520 UWORD 1 UWORD 1 <SQL_COLUMN_NAME> PTR 0x002a68b0 SWORD 32 SWORD * 0x00f3fa4e (8) SDWORD * 0x00000000 inetinfo 119:11f ENTER SQLColAttributes HSTMT 0x05802520 UWORD 1 UWORD 2 <SQL_COLUMN_TYPE> PTR 0x00000000 SWORD 0 SWORD * 0x00000000 SDWORD * 0x002a68d8 inetinfo 119:11f EXIT SQLColAttributes with return code 0 (SQL_SUCCESS) HSTMT 0x05802520 UWORD 1 UWORD 2 <SQL_COLUMN_TYPE> PTR 0x00000000 SWORD 0 SWORD * 0x00000000 SDWORD * 0x002a68d8 (11) inetinfo 119:11f ENTER SQLColAttributes HSTMT 0x05802520 UWORD 1 UWORD 6 <SQL_COLUMN_DISPLAY_SIZE> PTR 0x00000000 SWORD 0 SWORD * 0x00000000 SDWORD * 0x00f3fa50 inetinfo 119:11f EXIT SQLColAttributes with return code 0 (SQL_SUCCESS) HSTMT 0x05802520 UWORD 1 UWORD 6 <SQL_COLUMN_DISPLAY_SIZE> PTR 0x00000000 SWORD 0 SWORD * 0x00000000 SDWORD * 0x00f3fa50 (19) inetinfo 119:11f ENTER SQLBindCol HSTMT 0x05802520 UWORD 1 SWORD 1 <SQL_C_CHAR> PTR 0x002b5ac0 SDWORD 20 SDWORD * 0x002a68d4 inetinfo 119:11f EXIT SQLBindCol with return code 0 (SQL_SUCCESS) HSTMT 0x05802520 UWORD 1 SWORD 1 <SQL_C_CHAR> PTR 0x002b5ac0 SDWORD 20 SDWORD * 0x002a68d4 (91927008) inetinfo 119:11f ENTER SQLDisconnect HDBC 0x058022e0 inetinfo 119:11f EXIT SQLDisconnect with return code 0 (SQL_SUCCESS) HDBC 0x058022e0 inetinfo 119:11f ENTER SQLFreeConnect HDBC 0x058022e0 inetinfo 119:11f EXIT SQLFreeConnect with return code 0 (SQL_SUCCESS) HDBC 0x058022e0 inetinfo 119:11f ENTER SQLFreeEnv HENV 0x05801500 inetinfo 119:11f EXIT SQLFreeEnv with return code 0 (SQL_SUCCESS) HENV 0x05801500 inetinfo 119:11f ENTER SQLFreeStmt HSTMT 0x05802520 UWORD 1 <SQL_DROP> ...and heres the php.ini file [PHP] ;;;;;;;;;;;;;;;;;;; ; About this file ; ;;;;;;;;;;;;;;;;;;; ; This file controls many aspects of PHP's behavior. In order for PHP to ; read it, it must be named 'php.ini'. PHP looks for it in the current ; working directory, in the path designated by the environment variable ; PHPRC, and in the path that was defined in compile time (in that order). ; Under Windows, the compile-time path is the Windows directory. The ; path in which the php.ini file is looked for can be overriden using ; the -c argument in command line mode. ; ; The syntax of the file is extremely simple. Whitespace and Lines ; beginning with a semicolon are silently ignored (as you probably guessed). ; Section headers (e.g. [Foo]) are also silently ignored, even though ; they might mean something in the future (they probably won't). ; ; Options are specified using the syntax key = value or key = "complex value". ; Key names are *case sensitive*. foo = bar is different from FOO = bar. ; 'value' can be any number, word or keyword (keywords are On, Off, True, ; False, Yes and No, and are case insensitive). ; 'complex value' can be just about anything, expcept for " and a newline ; Boolean flags can be turned on using the values 1, On, True or Yes. ; They can be turned off using the values 0, Off, False or No. ; ; All the values in the php.ini-dist file correspond to the builtin ; defaults (that is, if no php.ini is used, or if you delete these lines, ; the builtin defaults will be identical). ;;;;;;;;;;;;;;;;;;;; ; Language Options ; ;;;;;;;;;;;;;;;;;;;; engine = On ; Enable the PHP scripting language engine under Apache short_open_tag = Off ; allow the <? tag. otherwise, only <?php and <script> tags are recognized. asp_tags = Off ; allow ASP-style <% %> tags precision = 14 ; number of significant digits displayed in floating point numbers y2k_compliance = Off ; whether to be year 2000 compliant (will cause problems with non y2k compliant browsers) ; Safe Mode safe_mode = Off safe_mode_exec_dir = ; Colors for Syntax Highlighting mode.
