New Comment:
Sorry, forgot the pcntl_waitpid during my 1st edit (see below).
ingres_connect($str_database, $str_username, $str_password);
if (ingres_query('select count(*) from auto_ldg_run')) {
print 'db ok during fork'."\n\n";
}
$int_pid = pcntl_fork();
if(!$int_pid) {
ingres_connect($str_database, $str_username, $str_password);
if (ingres_query('select count(*) from auto_ldg_run')) {
print 'db ok for child'."\n\n";
}
exit();
}
pcntl_waitpid ($int_pid, $str_status);
ingres_connect($str_database, $str_username, $str_password);
if (!ingres_query('select count(*) from auto_ldg_run')) {
print 'db not ok after fork'."\n\n";
}
exit(1);

Description:
------------
As per the manual ingres_connect connections are terminated when the
process exits. When a forked child exits the connection is terminated
permanently until the parent process is restarted.
Reproduce code:
---------------
ingres_connect($str_database, $str_username, $str_password);
if (ingres_query('select count(*) from table')) {
print 'db ok during fork'."\n\n";
}
$int_pid = pcntl_fork();
if(!$int_pid) {
ingres_connect($str_database, $str_username, $str_password);
if (ingres_query('select count(*) from table')) {
print 'db ok for child'."\n\n";
}
exit();
}
ingres_connect($str_database, $str_username, $str_password);
if (!ingres_query('select count(*) from table')) {
print 'db not ok after fork'."\n\n";
}
Expected result:
----------------
db ok during fork
db ok for child
Actual result:
--------------
db ok during fork
db ok for child
