time out if exceeded the time limit

[carobee]

Is there any way to monitor the message queue through php script?

Suppose my php script is receiving message from message queue. i wanted my php scipt to time out if certain sec say 30 sec are exceeded while receiving message from message queue. Is it possible?

i tried with set_time_limit( ) function but still the script doesnot time out. It waits till it receives the message.

want urgent help. thanks in advance

Check the value for max_execution_t ime in php.ini. In what context you are using set_time_limit( )?

i checked out , its 30 sec. but i guess when the php script comes to the code of receiving message it goes into wait state. how to take control at that time?

i used it so that i could set my own time

when the php script comes to the code of receiving message

Please explaing this, from where your script is receiving messages?

From PHP manual

When called, set_time_limit( ) restarts the timeout counter from zero. In other words, if the timeout is the default 30 seconds, and 25 seconds into script execution a call such as set_time_limit( 20) is made, the script will run for a total of 45 seconds before timing out.

i m sending message to the php script from a C prog

PHP Manual says

Note: The set_time_limit( ) function and the configuration directive max_execution_t ime only affect the execution time of the script itself. Any time spent on activity that happens outside the execution of the script such as system calls using system(), stream operations, database queries, etc. is not included when determining the maximum time that the script has been running.

.

Did you read the PHP manual?

Heya, carobee.

Since PHP doesn't support threading, your script will stop and wait for the system() call to finish before doing anything else.

If you want to enforce a time limit on your app, it will have to be done in your C program.

can i do something like fork a process, let the child process try to receive the process. now since no message is there in the message queue it will go into block state n return control to parent process. As soon as control comes back to the parent process it sends the time out messsage.
Is somethng like this is feasible?

[carobee]

i found the solution. Instead of doing in such a complex way i went for a nonblocking message receive call.In this way i could solve the problem easily
