Process Control support in PHP implements the Unix style of
|
|
process creation, program execution, signal handling and process
|
|
termination. Process Control should not be enabled within a
|
|
web server environment and unexpected results may happen if any
|
|
Process Control functions are used within a web server environment.

|
This documentation is intended to explain the general usage of
|
|
each of the Process Control functions. For detailed information
|
|
about Unix process control you are encouraged to consult your
|
|
systems documentation including fork(2), waitpid(2) and signal(2)
|
|
or a comprehensive reference such as Advanced Programming in the
|
|
UNIX Environment by W. Richard Stevens (Addison-Wesley).

PCNTL now uses ticks as the signal handle callback mechanism, which is
|
|
much faster than the previous mechanism. This change follows the same
|
|
semantics as using "user ticks". You use the <function>declare</function>
|
|
statement to specify the locations in your program where callbacks are
|
|
allowed to occur. This allows you to minimize the overhead of handling
|
|
asynchronous events. In the past, compiling PHP with pcntl enabled would
|
|
always incur this overhead, whether or not your script actually used
|
|
pcntl.
