stream_filter_removestream_get_contents
(PHP 5)
stream_get_contents — Reads remainder of a stream into a string
Opis
$handle
[, int $maxlength = -1
[, int $offset = -1
]] )
Identical to file_get_contents(), except that
stream_get_contents() operates on an already open
stream resource and returns the remaining contents in a string, up to
maxlength bytes and starting at the specified
offset.
Parametry
-
handle(resource) -
A stream resource (e.g. returned from fopen())
-
maxlength(integer) -
The maximum bytes to read. Defaults to -1 (read all the remaining buffer).
-
offset(integer) -
Seek to the specified offset before reading. If this number is negative, no seeking will occur and reading will start from the current position.
Zwracane wartości
Returns a string lub FALSE w przypadku niepowodzenia.
