Variables
boolean $append = true (line 54)

If set to true, appends to file. Otherwise overwrites it.

- access: protected

string $file (line 60)

Path to the target file.

- access: protected

resource $fp (line 66)

The file resource.

- access: protected

boolean $locking = true (line 48)

If set to true, the file is locked before appending. This allows concurrent access. However, appending without locking is faster so it should be used where appropriate.

TODO: make this a configurable parameter
