Hi Readers,

Heres what i'm trying to achieve:

A script, that uses multiple fsockopen()'s and simltaniously get feedback from each socket from fget()s. Now, since using a single fget() needs to be in a loop then it's not possible to have more than one loop going at the same time.

I was thinking of using a break command, then getting feedback from the other loops, and breaking each of them inside a encapsulating loop - however, this is VERY ineffective.

What I thought about doing was just using the same script launched multiple times, so it has diffrent proccesses running and therefore would be able to complete the task of having multiple loops running at the same time on the same system.

The problem I've found out is that on Unix (the desired OS breed), PHP can't be forked - so using a start.php script to execute multiple system() calls wouldn't work becuase PHP waits till the system() function has finished before carrying on with the rest of start.php.

i.e. The following won't work:

PHP Code:

for ($i = 0; $i < 5; $i++) {

  system ("/path/to/php /path/to/script.php &");

} 

Basically, i'm asking if anyone has a work around, or alternativley a answer to my problem?

I'd much appritiate it, or any help you can contribute.

Thanks in advance, or for atleast reading to this point

On all UNIX systems PHP can be forked.. if it is run from the command line and.. if it was compiled with --enable-pcntl.

See process controll functions in the manual.

Another option that you may wish to explore is register_tick_function ( string func [, mixed arg])

register_tick_function registers the function named by func to be executed when a tick is called.

A tick is an event that occurs for every N low-level statements executed by the parser within the declare block. The value for N is specified using ticks=N within the declare blocks's directive section.

The event(s) that occurs on each tick is specified using the register_tick_function().

Ticks are well suited for debugging, implementing simple multitasking, backgrounded I/O and many other tasks.
