Detailed Description

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

Definition at line 29 of file FSFile.php.

Constructor & Destructor Documentation

◆ __construct()

FSFile::__construct ( $path)

Sets up the file object.

Parameters
string$pathPath to temporary file on local disk

Reimplemented in TempFSFile.

Definition at line 41 of file FSFile.php.

References $path.

Member Function Documentation

◆ exists()

FSFile::exists ( )

Checks if the file exists.

Returns
bool

Reimplemented in MockFSFile.

Definition at line 59 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 188 of file FSFile.php.

◆ getPath()

FSFile::getPath ( )

Returns the file system path.

Returns
string

Definition at line 50 of file FSFile.php.

References $path.

Referenced by File\getThumbnailSource().

◆ 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$extThe file extension, or true to extract it from the filename. Set it to false to ignore the extension. Currently unused.
Returns
array

Reimplemented in MockFSFile.

Definition at line 105 of file FSFile.php.

References $mime, exists(), false, getSha1Base36(), getSize(), list, and placeholderProps().

◆ getPropsFromPath()

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

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

Parameters
string$pathAbsolute local filesystem path
string | bool$extThe 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

Reimplemented in MockFSFile.

Definition at line 166 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

◆ getSize()

FSFile::getSize ( )

Get the file size in bytes.

Returns
int|bool

Reimplemented in MockFSFile.

Definition at line 68 of file FSFile.php.

◆ getTimestamp()

FSFile::getTimestamp ( )

Get the file's last-modified timestamp.

Returns
string|bool TS_MW timestamp or false on failure

Reimplemented in MockFSFile.

◆ placeholderProps()

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
