Detailed Description

Simulation of a backend storage in memory.

All data in the backend is automatically deleted at the end of PHP execution. Since the data stored here is volatile, this is only useful for staging or testing.

Since:: 1.23

MemoryFileBackend::isPathUsableInternal ( $ storagePath )

Check if a file can be created or changed at a given storage path.

FS backends should check if the parent directory exists, files can be written under it, and that any file already there is writable. Backends using key/value stores should check if the container exists.

Parameters:

string $storagePath

Returns:: bool

Reimplemented from FileBackendStore.

Definition at line 37 of file MemoryFileBackend.php.

MemoryFileBackend::resolveHashKey ( $ storagePath ) [protected]

Get the absolute file system path for a storage path.

Parameters:

string $storagePath Storage path

Returns:: string|null
