Attach a filter to a stream

Parametry

Parametr Datový typ Výchozí hodnota Poznámka
$stream resource   The target stream.
$filtername string   The filter name.
$read_write int null, By default, stream_filter_pre­pend will attach the filter to the read filter chain if the file was opened for reading (i.e. File Mode: r, and/or +). The filter will also be attached to the write filter chain if the file was opened for writing (i.e. File Mode: w, a, and/or +). STREAM_FILTER_READ, STREAM_FILTER_WRI­TE, and/or STREAM_FILTER_ALL can also be passed to the read_write parameter to override this behavior. See stream_filter_ap­pend for an example of using this parameter.
$params mixed null This filter will be added with the specified params to the beginning of the list and will therefore be called first during stream operations. To add a filter to the end of the list, use stream_filter_ap­pend.
