Ok.But I guess that this behavior is not that anyone expect.

PHP signals are implemented with ticks
(http://us3.php.net/manual/en/control-structures.declare.php). Ticks are
events that occur every so much statements in a script. Since fgets()
blocks, no more statements are executed and no more ticks are fired.
This means that no signal arrives.

I do not know whether the current behavior is by design or by mistake,
so I cannot determine whether it is a bug or not. It would certainly be
desirable to be able to interrupt a blocking read by doing Ctrl-C.

Where I say:

'There is true?',

is

'That's true?'

The problem is that I need hit enter - exit from fgets - to run the
signal handler - but this is not the correct way - in python for
example, the signal handler are calling when the function are waiting
for a user input.

I found this page -
http://br2.php.net/manual/en/function.pcntl-signal.php
- the commentary
above:

'28-Mar-2006 07:26
Process handling is not available when using a blocking socket! Bear
this in mind.'

There is true?

Thank you for your bug report.

I don't fully understand the problem.

Is the problem that you have to hit enter for the signal handler to
run? Or that the line with 'echo $foo' is ran after the fgets?
