    28. Costanti di errore e log predefinite

  28. E_ERROR (1) Fatal run-time errors. These indicate errors that can not be recovered from, such as a memory allocation problem. Execution of the script is halted.
  29. E_WARNING (2) Run-time warnings (non-fatal errors). Execution of the script is not halted.
  30. E_PARSE (4) Compile-time parse errors. Parse errors should only be generated by the parser.
  31. E_NOTICE (8) Run-time notices. Indicate that the script encountered something that could indicate an error, but could also happen in the normal course of running a script.
  32. E_CORE_ERROR (16) Fatal errors that occur during PHP’s initial startup. This is like an E_ERROR, except it is generated by the core of PHP.
  33. E_CORE_WARNING (32) Warnings (non-fatal errors) that occur during PHP’s initial startup. This is like an E_WARNING, except it is generated by the core of PHP.
  34. E_COMPILE_ERROR (64) Fatal compile-time errors. This is like an E_ERROR, except it is generated by the Zend Scripting Engine.
  35. E_COMPILE_WARNING (128) Compile-time warnings (non-fatal errors). This is like an E_WARNING, except it is generated by the Zend Scripting Engine.
  36. E_USER_ERROR (256) User-generated error message. This is like an E_ERROR, except it is generated in PHP code by using the PHP function trigger_error().
  37. E_USER_WARNING (512) User-generated warning message. This is like an E_WARNING, except it is generated in PHP code by using the PHP function trigger_error().
  38. E_USER_NOTICE (1024) User-generated notice message. This is like an E_NOTICE, except it is generated in PHP code by using the PHP function trigger_error().
  39. E_STRICT (2048) Enable to have PHP suggest changes to your code which will ensure the best interoperability and forward compatibility of your code. Since PHP 5 but not included in E_ALL until PHP 5.4.0
  40. E_RECOVERABLE_ERROR (4096) Catchable fatal error. It indicates that a probably dangerous error occurred, but did not leave the Engine in an unstable state. If the error is not caught by a user defined handle (see also set_error_handler()), the application aborts as it was an E_ERROR. Since PHP 5.2.0
  41. E_DEPRECATED (8192) Run-time notices. Enable this to receive warnings about code that will not work in future versions. Since PHP 5.3.0
  42. E_USER_DEPRECATED (16384) User-generated warning message. This is like an E_DEPRECATED, except it is generated in PHP code by using the PHP function trigger_error(). Since PHP 5.3.0
  43. E_ALL (32767) All errors and warnings, as supported, except of level E_STRICT prior to PHP 5.4.0.
