bzread
(PHP 4 >= 4.0.4, PHP 5)
bzread -- Binary safe bzip2 file read
Description
string
bzread ( resource bz [, int length])
bzread() reads up to
length bytes from the bzip2 file pointer
referenced by bz. Reading stops when
length (uncompressed) bytes have been read
or EOF is reached, whichever comes first. If the optional
parameter length is not specified,
bzread() will read 1024 (uncompressed) bytes
at a time.
