PHP Handlers¶
PHP handlers are methods which are called to customize the processing of specific events. All those handlers have a default handler, which is used until a new one is configured.
Handlers are usually named by their setting function :
- Errors
set_error_handler()
set_exception_handler()
- Sessions
session_set_save_handler()
session_register_shutdown()
- Execution
register_shutdown_function()
- Ticks
register_tick_function()
- Headers
header_register_callback()
- Streams
stream_register_wrapper()
stream_wrapper_register()
stream_filter_register()
- Autoload
spl_autoload_register()
PHP handlers may be functions, closures and arrow functions.
