Properties
$defaultLogFileTemplate
Default log file path
protected
string
$defaultLogFileTemplate
= '/log/typo3_%s.log'
$logFile
Log file path, relative to TYPO3's base project folder
protected
string
$logFile
= ''
$logFileHandles
Log file handle storage
protected
static array<string|int, mixed>
$logFileHandles
= []
To avoid concurrent file handles on a the same file when using several FileWriter instances, we share the file handles in a static class variable
Tags
$logFileHandlesCount
Keep track of used file handles by different fileWriter instances
protected
static array<string|int, mixed>
$logFileHandlesCount
= []
As the logger gets instantiated by class name but the resources are shared via the static $logFileHandles we need to track usage of file handles to avoid closing handles that are still needed by different instances. Only if the count is zero may the file handle be closed.
$logFileInfix
protected
string
$logFileInfix
= ''
Methods
__construct()
Constructor, opens the log file handle
public
__construct([array<string|int, mixed> $options = [] ]) : mixed
Parameters
- $options : array<string|int, mixed> = []
__destruct()
Destructor, closes the log file handle
public
__destruct() : mixed

closeLogFile()
Closes the log file handle.
protected
closeLogFile() : mixed
createHtaccessFile()
Creates .htaccess file inside a new directory to access protect it
protected
createHtaccessFile(string $htaccessFile) : mixed
Parameters
- $htaccessFile : string
-
Path of .htaccess file
createLogFile()
Creates the log file with correct permissions and parent directories, if needed
protected
createLogFile() : mixed
formatContextValue()
Escape or quote a value from the context appropriate for the output.
protected
formatContextValue(string $value) : string
Note: In some output cases, escaping should not be done here but later on output, such as if it's being written to a database for later display.
Parameters
- $value : string
Return values
stringformatException()
Formats an exception into a string.
protected
formatException(Throwable $ex) : string
The format here is nearly the same as just casting an exception to a string, but omits the full class namespace and stack trace, as those get very long.
Parameters
- $ex : Throwable
Return values
stringgetDefaultLogFileName()
Returns the path to the default log file.
protected
getDefaultLogFileName() : string
Uses the defaultLogFileTemplate and replaces the %s placeholder with a short MD5 hash based on a static string and the current encryption key.
Return values
stringinterpolate()
Interpolates context values into the message placeholders.
protected
interpolate(string $message[, array<string|int, mixed> $context = [] ]) : string
Parameters
- $message : string
- $context : array<string|int, mixed> = []
