Question

I want to run more than 1 php processes using exec(command). Each of these (actually they are the same) may last long, and I dont want wait one to finish than launch another.

in other words, I want

for($i=0; $i < $count; $i++) {
   exec($command);
}

this code to be executed without waiting for return from previous process.

Any ideas ?

Thanks in advance!

Take a look at the doc:

If a program is started with this function, in order for it to
continue running in the background, the output of the program must be
redirected to a file or another output stream. Failing to do so will
cause PHP to hang until the execution of the program ends.
