As of PHP 4.3, this function can (potentially) work on any kind of
|
|
stream. In PHP 4.3, socket based streams are still the only kind
|
|
supported in the PHP core, although streams from other extensions
|
|
may support this function.

<note>
|
|
<para>
|
|
This function doesn't work with advanced operations like
|
|
<function>stream_socket_recvfrom</function>, use
|
|
<function>stream_select</function> with timeout parameter instead.
|
|
</para>
|
|
</note>
|
|
<para>
|
|
This function was previously called as
|
|
<function>set_socket_timeout</function> and later
|
|
<function>socket_set_timeout</function> but this usage is deprecated.
