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.

Member Function Documentation

exists()

FSFile::exists

(

)

Checks if the file exists.

Returns

bool

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

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

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

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

false|string False on failure
