getData [line 158]

void getData(
[
$length = -1])

Reads some data from the current file

If the end of the file is reached, returns null If $length is not specified, reads up to the end of the file If $length is specified reads up to $length

Overridden in child classes as:

File_Archive_Reader_Memory::getData()

File_Archive_Reader_File::getData()

Parameters:

$length —

getDataFilename [line 150]

the getDataFilename(
)

If the current file of the archive is a physical file,

Return:
name of the physical file containing the data or null if no such file exists
The data filename may not be the same as the filename.

Overridden in child classes as:

File_Archive_Reader_File::getDataFilename()

[ Top ]

getFilename [line 118]

string getFilename(
)

Returns the name of the file currently read by the reader

Warning: undefined behaviour if no call to next have been done or if last call to next has returned false

Return: Name of the current file

Overridden in child classes as:

File_Archive_Reader_Memory::getFilename()

File_Archive_Reader_File::getFilename()

getMime [line 136]

void getMime(
)

Returns the MIME associated with the current file

The default function does that by looking at the extension of the file

Overridden in child classes as:

File_Archive_Reader_Memory::getMime()

File_Archive_Reader_File::getMime()

[ Top ]

getStandardURL [line 95]

void getStandardURL(
string
$path)

Returns the standard path

Changes \ to / Removes the .. and . from the URL

Parameters:

string $path — a valid URL that may contain . or .. and \

getStat [line 130]

void getStat(
)

Returns an array of statistics about the file (see the PHP stat function for more information)

The returned array may be empty, even if readers should try their best to return as many data as possible

Overridden in child classes as:

File_Archive_Reader_Memory::getStat()

File_Archive_Reader_File::getStat()

[ Top ]

next [line 48]

bool next(
)

Move to the next file in the reader

Return: true iif no more files are available

Overridden in child classes as:

File_Archive_Reader_Memory::next(): The subclass should overwrite this function to change the filename, stat

File_Archive_Reader_File::next()

[ Top ]

select [line 61]

bool select(
string
$filename, [bool
$close = true])

Move to the next file whose name is in directory $filename or is exactly $filename

Return: whether the file was found in the archive or not

Parameters:

string	`$filename`	—	Name of the file to find in the archive
bool	`$close`	—	If true, close the reader and search from the first file

sendData [line 192]

void sendData(

&$writer, [
$bufferSize = 102400])

Sends the current file to the Writer $writer

The data will be sent by chunks of at most $bufferSize bytes

Parameters:

	`&$writer`	—
	`$bufferSize`	—

skip [line 169]

void skip(

$length)

Skip some data and returns how many bytes have been skipped

This is strictly equivalent to return strlen(getData($length)) But could be far more efficient

Overridden in child classes as:

File_Archive_Reader_Memory::skip()

File_Archive_Reader_File::skip()

Parameters:

$length —
