A crash occurs when ODBC functions are called with an "or die" statement. BUT this only happens when an error arises AND the ODBC or die statement is made within a user defined function. Doing the same thing without a creating a user defined function caused no problem. Doing the same exact procedures with MySQL functions caused no problem. This bug didn't exist in PHP 3.0.11. Samples of each test variation is below, along with a Dr. Watson report. <?php # This works fine in PHP 3.0.11 # BUT CRASHES IN 4.0.3 echo "<h3>ODBC field_len or die Called via Function</h3>"; echo "PHP Version: " . phpversion(); function SomeFunction() { global $RecordSetFieldCount; global $RecordSet; for ($Counter = 0; $Counter < $RecordSetFieldCount; $Counter++) { echo "<br />Counter: $Counter"; # Uncommenting one of these causes crash in 4.0.3. $Output[] = @odbc_field_len($RecordSet, $Counter+1) or die ("Went beyond field index."); # $Output[] = @odbc_field_type($RecordSet, $Counter+1) or die ("Went beyond field index."); # $Output[] = @odbc_num_fields() or die ("Went beyond field index."); # Uncommenting this works fine in both versions. # $Output[] = @odbc_field_len($RecordSet, $Counter+1); # $Output[] = @odbc_num_fields(); } } $Connection = @odbc_connect("StatsFInAccess", "", "", SQL_CUR_USE_ODBC); $QueryString = "select * from States order by SC"; $RecordSet = @odbc_exec($Connection,"$QueryString"); $RecordSetFieldCount = 4; SomeFunction(); ?> <?php /* # This works fine in PHP 3.0.11 and 4.0.3 echo "<h3>ODBC field_len or die Called Directly</h3>"; echo "PHP Version: " . phpversion(); $Connection = @odbc_connect("StatsFInAccess", "", "", SQL_CUR_USE_ODBC); $QueryString = "select * from States order by SC"; $RecordSet = @odbc_exec($Connection,"$QueryString"); $RecordSetFieldCount = 4; for ($Counter = 0; $Counter < $RecordSetFieldCount; $Counter++) { echo "<br />Counter: $Counter"; $Output[] = @odbc_field_len($RecordSet, $Counter+1) or die ("Went beyond field index."); } */ ?> <?php /* # This works fine in PHP 3.0.11 and 4.0.3 echo "<h3>MySQL field_len or die Called via Function</h3>"; echo "PHP Version: " . phpversion(); function SomeFunction() { global $RecordSetFieldCount; global $RecordSet; for ($Counter = 0; $Counter < $RecordSetFieldCount; $Counter++) { echo "<br />Counter: $Counter"; $Output[] = @mysql_field_len($RecordSet, $Counter) or die ("Went beyond field index."); } } $Connection = @mysql_connect("localhost", "jdoe", "TheNumberGal"); $Database = @mysql_select_db("StatsF",$Connection); $QueryString = "select * from States order by SC"; $RecordSet = @mysql_query("$QueryString",$Connection); $RecordSetFieldCount = 4; SomeFunction(); */ ?> <?php /* Microsoft (R) Windows NT (TM) Version 4.00 DrWtsn32 Copyright (C) 1985-1996 Microsoft Corp.
