[SOLVED] msg_receive question..

[crichard6069]

Hi All - I'm very new to PHP but the project I'm doing at work requires it.. with that said, I have a simple question I'm hoping someone can help me with.

 

I have a need to communicate between a C program and PHP and it's looking like a Linux message queue is the way to go. I've written a small C program that puts a message in the queue (and reads from the queue). I've now "advanced" this to putting the message in the queue through the C program and reading it from the queue with a PHP script.

 

Currently I'm running the php script from the shell and it IS reading the message from the queue. However, it seems to be dumping off the first 4 characters of the message. Why is this? If I put a message in the queue from the C app that says "Testing" all I get when I read the queue in PHP is "ing".

 

PHP Code to read the queue:

 

<?

    echo "Starting\n\n";

 

    $MSGKEY = 3;   

    $mqId = msg_get_queue($MSGKEY);

 

    msg_receive($mqId, 0, $msg_type, 2000, $msg, false, 0, $error);

    echo "Message: $msg\n";

    echo "Error: $error\n";

 

    echo "Finished\n";

 

?>

 

I'm just trying to figure out how to get the message in it's entirety. The C app is creating the queue and putting the message there. PHP just needs to attach to it and read the message.

 

Thanks..

Chad
