/**
* Receive a message from a message queue
* @link https://php.net/manual/en/function.msg-receive.php
* @param SysvMessageQueue|resource $queue
* @param int $desired_message_type <p>
* If <i>desiredmsgtype</i> is 0, the message from the front
* of the queue is returned. If <i>desiredmsgtype</i> is
* greater than 0, then the first message of that type is returned.
* If <i>desiredmsgtype</i> is less than 0, the first
* message on the queue with the lowest type less than or equal to the
* absolute value of <i>desiredmsgtype</i> will be read.
* If no messages match the criteria, your script will wait until a suitable
* message arrives on the queue. You can prevent the script from blocking
* by specifying <b>MSG_IPC_NOWAIT</b> in the
* <i>flags</i> parameter.
* </p>
* @param int &$received_message_type <p>
* The type of the message that was received will be stored in this
* parameter.
* </p>
* @param int $max_message_size <p>
* The maximum size of message to be accepted is specified by the
* <i>maxsize</i>; if the message in the queue is larger
* than this size the function will fail (unless you set
* <i>flags</i> as described below).
* </p>
* @param mixed &$message <p>
* The received message will be stored in <i>message</i>,
* unless there were errors receiving the message.
* </p>
* @param bool $unserialize [optional] <p>
* If set to
* <b>TRUE</b>, the message is treated as though it was serialized using the
* same mechanism as the session module. The message will be unserialized
* and then returned to your script. This allows you to easily receive
* arrays or complex object structures from other PHP scripts, or if you
* are using the WDDX serializer, from any WDDX compatible source.
* </p>
* <p>
* If <i>unserialize</i> is <b>FALSE</b>, the message will be
* returned as a binary-safe string.
* </p>
* @param int $flags [optional] <p>
* The optional <i>flags</i> allows you to pass flags to the
* low-level msgrcv system call. It defaults to 0, but you may specify one
* or more of the following values (by adding or ORing them together).
* <table>
* Flag values for msg_receive
* <tr valign="top">
* <td><b>MSG_IPC_NOWAIT</b></td>
* <td>If there are no messages of the
* <i>desiredmsgtype</i>, return immediately and do not
* wait. The function will fail and return an integer value
* corresponding to <b>MSG_ENOMSG</b>.
* </td>
* </tr>
* <tr valign="top">
* <td><b>MSG_EXCEPT</b></td>
* <td>Using this flag in combination with a
* <i>desiredmsgtype</i> greater than 0 will cause the
* function to receive the first message that is not equal to
* <i>desiredmsgtype</i>.</td>
* </tr>
* <tr valign="top">
* <td><b>MSG_NOERROR</b></td>
* <td>
* If the message is longer than <i>maxsize</i>,
* setting this flag will truncate the message to
* <i>maxsize</i> and will not signal an error.
* </td>
* </tr>
* </table>
* </p>
* @param int $error_code [optional] <p>
* If the function fails, the optional <i>errorcode</i>
* will be set to the value of the system errno variable.
* </p>
* @return bool <b>TRUE</b> on success or <b>FALSE</b> on failure.
* <p>
* Upon successful completion the message queue data structure is updated as
* follows: msg_lrpid is set to the process-ID of the
* calling process, msg_qnum is decremented by 1 and
* msg_rtime is set to the current time.
* </p>
