I wasn´t unable to watch the forking process completely. Execute this script, it shows that
a) sequential executing with for() equals tick executing, time-wise, I assume that this is not ok,
well maybe I ran into the WTF thing and did not understand what´s going on, I thought these functions
were executed concurrently, what is (apparently) not the case. Ok. they must be spawned sequentially,
but even replacing usleep with sleep(1) keeps these proportions in time difference.
b) referenced variable $b is only increased in every function in for(), that´s ok.
$b=3;
function foo(&$a) {
$a++;
usleep(10000000);
$x=substr(microtime(),0,10)."\n";
print "(1[$a])$x\n"; }
function zoo(&$b) {
$b++;
$x=substr(microtime(),0,10)."\n";
print "(2[$b])$x\n"; }
function boo(&$b) {
$b++;
$x=substr(microtime(),0,10)."\n";
print "(3[$b])$x\n"; }
register_tick_function("foo",$b);
register_tick_function("zoo",$b);
register_tick_function("boo",$b);
declare (ticks = 3)
{ 1;1;1;1;1;1;1;1;1; }
?><BR><?php
for ($i=1;$i<=3;$i++) {
foo($b);
zoo($b);
boo($b); }
