# SAMConnection->receive()

(No version information available, might be only in CVS)

SAMConnection->receive() — Receive a message from a queue or subscription.

### Description

SAMConnection
SAMMessage receive ( string `$target` [, array `$properties` ] )

### Parameters

`target`

  The identity of the queue, topic or subscription from which to receive the message.

`properties`

  An optional associative array of properties describing other parameters to control the receive operation.

  Property name | Possible values
  --- | ---
  SAM_CORRELID | Used to request selection of the message to receive based upon the correlation id string of the message.
  SAM_MESSAGEID | Used to request selection of the message to receive based upon the message id string of the message.
  SAM_WAIT | Timeout value in milliseconds to control how long the request should block waiting to receive a message before returning with a failure if no message is available on the queue or topic. The default value is 0 meaning wait indefinitely and should be used with caution as the request may wait until the overall PHP script processing time limit has expired if no message becomes available.

### Return Values

This method returns a SAMMessage object or `FALSE` if an error occurs.

### Examples

Example#1 Receiving a message from a queue

`<?php
$msg = $conn->receive('queue://receive/test');
if (!$msg) {
// The receive failed!
echo "Receive failed ($conn->errno) $conn->error";
}
?>`

Example#2 Receiving a message from a queue with options

In this example the SAM_CORRELID option is used to specify a correlation id string to be used to identify the message to receive. A wait timeout of 10 seconds is also specified.

`<?php
$msg = $conn->receive('queue://receive/test', array(SAM_CORRELID => $token, SAM_WAIT => 10000));
?>`

Example#3 Receiving a message from a subscription

In this example we show how to receive a message from a subscription id.

`<?php
$msg = $conn->receive($subscriptionName);
if (!$msg) {
// The receive failed!
echo "Receive failed ($conn->errno) $conn->error";
}
?>`

Please note that $subscriptionName is a subscription id returned from an earlier subscribe call.
