(PHP ActiveX) Using DebugLogFilePath to Debug a Crash

If a crash is suspected to occur within a Chilkat method call, it can be debugged using the VerboseLogging and DebugLogFilePath as shown here.

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows Note: The php_com_dotnet.dll may need to be enabled inside of php.ini.

// If a crash is suspected to occur within a Chilkat method call, it can be debugged using the VerboseLogging and DebugLogFilePath as shown here.
// 
// NOTE: The same technique applies for any Chilkat class that has the DebugLogFilePath property.
// Most Chilkat classes have DebugLogFilePath.

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Crypt2')
$crypt = new COM("Chilkat.Crypt2");

// First make sure VerboseLogging is turned on.
$crypt->VerboseLogging = 1;

// Set the DebugLogFilePath to the path of a log file that will be created automatically.
// If the file already exists, Chilkat will append to it.
$crypt->DebugLogFilePath = 'c:/someDir/debugLog.txt';

// Reproduce the problem.

// ...
$success = $crypt->VerifyP7M('c:/someDir/someFile.p7m');
// ...

// If a crash occurred within Chilkat, then the debugLog.txt will contain information that
// can be sent to support@chilkatsoft.com

// ------------------------------------------------------------------------------------------------
// Note: Given that the debug log file is always appended, the log file might grow 
// to a very large size.  You can prevent the continual growth of the log file by
// deleting the log file at certain points, such as after a Chilkat method returns.
// 
// Given that we're only interested in the log file for Chilkat calls that crash or hang,
// it's OK to delete the log file after a Chilkat method that returns.
// 
// The next call to a Chilkat method will re-create the log file.  If the Chilkat call crashes
// or hangs, then you'll be left with just the log of the crash or hang.
