  Modified files:              
    /phpdoc/en/language operators.xml 
  Log:
  Fixed example, added note that @foreach doesn't work,
  added note that db-functions usually don't cause
  a php error, and finally added an example
  to show that its use isn't restricted to
  functions

+     Most database-functions do not return PHP-errors, rather,
