<function>stream_context_get_default</function> devuelve el contexto por

defecto que se utiliza con las funciones de ficheros como
|
|
<function>fopen</function>, <function>file_get_contents</function>, etc,
|
|
cuando se utilizan sin parámetro de contexto. Las opciones del contexto
|
|
por defecto pueden especificarse opcionalmente con la misma
|
|
sintaxis que para <function>stream_context_create</function>.
