Detailed Description

Advanced debug/log system.

The eZ debug library is used to handle debug information. It can display information on screen and/or write it to log files.

You can enable on-screen debug information for specific IP addresses.

Timing points can be placed in the code to time the different sections of code.

Each debug message can be turned on/off by using the showTypes() function.

PHP error messages can also be shown using setHandleType().

  // write a temporary debug message
  eZDebug::writeDebug( "Test" );

  // write a notice
  eZDebug::writeNotice( "Image found" );

  // write a warning
  eZDebug::writeWarning( "Image not found, using default" );

  // write an error
  eZDebug::writeError( "Object not found, bailing.." );

  // add a timing points
  eZDebug::addTimingPoint( "Module Found" );

  //.... code

  eZDebug::addTimingPoint( "Module loading" );

  // print the results on screen.
  eZDebug::printReport();
