Inherited Methods

Class: Log

Log::alert(): A convenience function for logging an alert event. It will log a message at the PEAR_LOG_ALERT log level.
Log::attach(): Adds a Log_observer instance to the list of observers that are listening for messages emitted by this Log instance.
Log::close(): Abstract implementation of the close() method.
Log::crit(): A convenience function for logging a critical event. It will log a message at the PEAR_LOG_CRIT log level.
Log::debug(): A convenience function for logging a debug event. It will log a message at the PEAR_LOG_DEBUG log level.
Log::detach(): Removes a Log_observer instance from the list of observers.
Log::emerg(): A convenience function for logging a emergency event. It will log a message at the PEAR_LOG_EMERG log level.
Log::err(): A convenience function for logging a error event. It will log a message at the PEAR_LOG_ERR log level.
Log::factory(): Attempts to return a concrete Log instance of type $handler.
Log::flush(): Abstract implementation of the flush() method.
Log::getIdent(): Returns the current identification string.
Log::getMask(): Returns the current level mask.
Log::getPriority(): Returns the current default priority.
Log::info(): A convenience function for logging a information event. It will log a message at the PEAR_LOG_INFO log level.
Log::isComposite(): Indicates whether this is a composite class.
Log::log(): Abstract implementation of the log() method.
Log::MASK(): Calculate the log mask for the given priority.
Log::MAX(): Calculate the log mask for all priorities less than or equal to the given priority. In other words, $priority will be the highests priority matched by the resulting mask.
Log::MIN(): Calculate the log mask for all priorities greater than or equal to the given priority. In other words, $priority will be the lowest priority matched by the resulting mask.
Log::notice(): A convenience function for logging a notice event. It will log a message at the PEAR_LOG_NOTICE log level.
Log::open(): Abstract implementation of the open() method.
Log::priorityToString(): Returns the string representation of a PEAR_LOG_* integer constant.
Log::setIdent(): Sets this Log instance's identification string.
Log::setMask(): Set and return the level mask for the current Log instance.
Log::setPriority(): Sets the default priority to the specified value.
Log::singleton(): Attempts to return a reference to a concrete Log instance of type $handler, only creating a new instance if no log instance with the same parameters currently exists.
Log::stringToPriority(): Returns the the PEAR_LOG_* integer constant for the given string representation of a priority name. This function performs a case-insensitive search.
Log::UPTO(): Calculate the log mask for all priorities up to the given priority.
Log::warning(): A convenience function for logging a warning event. It will log a message at the PEAR_LOG_WARNING log level.

Method Detail

Log_file (Constructor) [line 98]

Log_file Log_file(
string
$name, [string
$ident = ''], [array
$conf = array()], [int
$level = PEAR_LOG_DEBUG])

Constructs a new Log_file object.

Access: public

Parameters:

string	`$name`	—	Ignored.
string	`$ident`	—	The identity string.
array	`$conf`	—	The configuration array.
int	`$level`	—	Log messages up to and including this level.

)

Destructor

close [line 235]

void close(
)

Closes the log file if it is open.

Access: public

Overrides Log::close() (Abstract implementation of the close() method.)

[ Top ]

flush [line 251]

void flush(
)

Flushes all pending data to the file handle.

Since: Log 1.8.2
Access: public

Overrides Log::flush() (Abstract implementation of the flush() method.)

[ Top ]

log [line 268]

boolean log(
mixed
$message, [string
$priority = null])

Logs $message to the output window. The message is also passed along to any Log_observer instances that are observing this Log.

Return: True on success or false on failure.
Access: public

Overrides Log::log() (Abstract implementation of the log() method.)

Parameters:

mixed	`$message`	—	String or object containing the message to log.
string	`$priority`	—	The priority of the message. Valid values are: PEAR_LOG_EMERG, PEAR_LOG_ALERT, PEAR_LOG_CRIT, PEAR_LOG_ERR, PEAR_LOG_WARNING, PEAR_LOG_NOTICE, PEAR_LOG_INFO, and PEAR_LOG_DEBUG.

open [line 204]

void open(
)

Opens the log file for output. If the specified log file does not already exist, it will be created. By default, new log entries are appended to the end of the log file.

This is implicitly called by log(), if necessary.

Access: public

Overrides Log::open() (Abstract implementation of the open() method.)
