When a child process errors out such as PHP error/warning/notice, is there a way to tell from the parent process? I try the following code but it returns exit normally.
<?php
$pid = pcntl_fork();
if ($pid > 0)
{
echo "pid: $pid
";
$status = 0;
pcntl_waitpid($pid, $status);
if (pcntl_wifsignaled($status))
echo "child crashed
";
if (pcntl_wifexited($status))
echo "child exited normally
";
if (pcntl_wifstopped($status))
echo "child stopped
";
}
else if ($pid == 0)
{
$n = 0;
while (++$n < 10)
{
echo ".";
sleep(1);
if ($n == 8)
{
// to cause a crash
// $n = $n / 0;
$a = "a";
unserialize(str_replace('1', 2147483647, serialize($a)));
}
}
}
?>
