Stream Contexts
A context
is a set of parameters
and
wrapper specific options
which modify or enhance the
behavior of a stream. Contexts
are created using
stream_context_create() and can be passed to most
filesystem related stream creation functions (i.e. fopen(),
file(), file_get_contents(), etc...).
Options
can be specified when calling
stream_context_create(), or later using
stream_context_set_option().
A list of wrapper specific options
can be found in the
Context options and parameters chapter.
Parameters
can be specified for
contexts
using the
stream_context_set_params() function.
