Detailed Description

Class representing a non-directory file on the file system.

Constructor & Destructor Documentation

__construct()

FSFile::__construct

(

$path

)

Sets up the file object.

Parameters

string

$path

Path to temporary file on local disk

Reimplemented in TempFSFile.

Definition at line 44 of file FSFile.php.

References $path.

Member Function Documentation

exists()

FSFile::exists

(

)

Checks if the file exists.

Returns

bool

Definition at line 62 of file FSFile.php.

Referenced by getProps().

extensionFromPath()

static FSFile::extensionFromPath ( $path )

static

Get the final file extension from a file system path.

Parameters

string

$path

Returns

string

Definition at line 195 of file FSFile.php.

References $path.

getPath()

FSFile::getPath

(

)

Returns the file system path.

Returns

string

Definition at line 53 of file FSFile.php.

References $path.

getProps()

FSFile::getProps

(

$ext = true

)

Get an associative array containing information about a file with the given storage path.

Resulting array fields include:

• fileExists
• size (filesize in bytes)
• mime (as major/minor)
• file-mime (as major/minor)
• sha1 (in base 36)
• major_mime
• minor_mime

Parameters

string | bool

$ext

The file extension, or true to extract it from the filename. Set it to false to ignore the extension. Currently unused.

Returns

array

Definition at line 112 of file FSFile.php.

getPropsFromPath()

static FSFile::getPropsFromPath ( $path, $ext = true )

static

Get an associative array containing information about a file in the local filesystem.

Parameters

string	$path	Absolute local filesystem path
string | bool	$ext	The file extension, or true to extract it from the filename. Set it to false to ignore the extension.

Returns

array

Definition at line 209 of file FSFile.php.

getSha1Base36()

FSFile::getSha1Base36

(

$recache = false

)

Get a SHA-1 hash of a file in the local filesystem, in base-36 lower case encoding, zero padded to 31 digits.

160 log 2 / log 36 = 30.95, so the 160-bit hash fills 31 digits in base 36 fairly neatly.

Parameters

bool

$recache

Returns

bool|string False on failure

Definition at line 173 of file FSFile.php.

getSha1Base36FromPath()

static FSFile::getSha1Base36FromPath ( $path )

static

Get a SHA-1 hash of a file in the local filesystem, in base-36 lower case encoding, zero padded to 31 digits.

160 log 2 / log 36 = 30.95, so the 160-bit hash fills 31 digits in base 36 fairly neatly.

Parameters

string

$path

Returns

bool|string False on failure

FSFile::getSize

(

)

Get the file size in bytes.

Returns

int|bool

Returns

string|bool TS_MW timestamp or false on failure

Definition at line 84 of file FSFile.php.

static FSFile::placeholderProps ( )

static

Placeholder file properties to use for files that don't exist.

Resulting array fields include:

• fileExists
• size (filesize in bytes)
• mime (as major/minor)
• file-mime (as major/minor)
• sha1 (in base 36)
• major_mime
• minor_mime
