This is called blocking; you can prevent blocking by setting the optional <CODE CLASS="parameter" >blocking</CODE > parameter to <TT CLASS="constant" ><B >FALSE</B ></TT >, in which case <B CLASS="function" >msg_send()</B > will immediately return <TT CLASS="constant" ><B >FALSE</B ></TT > if the message is too big for the queue, and set the optional <CODE CLASS="parameter" >errorcode</CODE > to <TT CLASS="constant" ><B >MSG_EAGAIN</B ></TT >, indicating that you should try to send your message again a little later on. </P ><P > The optional <CODE CLASS="parameter" >serialize</CODE > controls how the <CODE CLASS="parameter" >message</CODE > is sent. <CODE CLASS="parameter" >serialize</CODE > defaults to <TT CLASS="constant" ><B >TRUE</B ></TT > which means that the <CODE CLASS="parameter" >message</CODE > is serialized using the same mechanism as the session module before being sent to the queue. This allows complex arrays and objects to be sent to other PHP scripts, or if you are using the WDDX serializer, to any WDDX compatible client. </P ><P > Upon successful completion the message queue data structure is updated as follows: <CODE CLASS="parameter" >msg_lspid</CODE > is set to the process-ID of the calling process, <CODE CLASS="parameter" >msg_qnum</CODE > is incremented by 1 and <CODE CLASS="parameter" >msg_stime</CODE > is set to the current time. </P ><P > See also <A HREF="function.msg-remove-queue.html" ><B CLASS="function" >msg_remove_queue()</B ></A >, <A HREF="function.msg-receive.html" ><B CLASS="function" >msg_receive()</B ></A >, <A HREF="function.msg-stat-queue.html" ><B CLASS="function" >msg_stat_queue()</B ></A > and <A HREF="function.msg-set-queue.html" ><B CLASS="function" >msg_set_queue()</B ></A >. </P ></DIV ><DIV CLASS="NAVFOOTER" ><HR ALIGN="LEFT" WIDTH="100%"><TABLE SUMMARY="Footer navigation table" WIDTH="100%" BORDER="0" CELLPADDING="0" CELLSPACING="0" ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" ><A HREF="function.msg-remove-queue.html" ACCESSKEY="P" >Anterior</A ></TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" ><A HREF="index.html" ACCESSKEY="H" >Principal</A ></TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" ><A HREF="function.msg-set-queue.html" ACCESSKEY="N" >Próxima</A ></TD ></TR ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" >msg_remove_queue</TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" ><A HREF="ref.sem.html" ACCESSKEY="U" >Acima</A ></TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" >msg_set_queue</TD ></TR ></TABLE ></DIV ></BODY ></HTML >
