serialize -
The optional
serializecontrols how themessageis sent.serializedefaults toTRUEwhich means that themessageis 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. -
blocking -
If the message is too large to fit in the queue, your script will wait until another process reads messages from the queue and frees enough space for your message to be sent. This is called blocking; you can prevent blocking by setting the optional
blockingparameter toFALSE, in which case msg_send() will immediately returnFALSEif the message is too big for the queue, and set the optionalerrorcodetoMSG_EAGAIN, indicating that you should try to send your message again a little later on. -
errorcode -

msg_stime is set to the current time.
