PHPINFO is making or breaking my page

lucasrd

I have a really strange error I've never seen and I"ve been programming PHP for nearly 6 years...

This code does nothing and hangs

<?php
$c = oci_connect("user","pass","service");
echo $c;
oci_close($c);

?>

This code executes and prints out Resource Id #4 followed by the normal phpinfo output.

<?php
$c = oci_connect("user","pass","service");
echo $c;
oci_close($c);
phpinfo();
?>

I'm about ready to shoot myself!!!

I'd say... don't try to echo resources! :p

lucasrd

I was echoing the resource to show that it wasn't connecting....the same thing happens if I, say, loop through and print my result set returned....it displays when i call phpinfo() but hangs if I dont and the resource is not usable....

My guess is something weird going on with buffers.

<?php
$c = oci_connect("user","pass","service");
echo $c;
oci_close($c);
@ob_end_flush();
flush();
?>

Are you using mod_gzip in apache? Does the code still hang if running from the command line?

Ok, I did some more digging....when I include the phpinfo() everythign works as expected....when I don't have it on there, I get this in my apache error_log file:

[Thu Jun  9 09:18:30 2005] [notice] child pid 20093 exit signal Segmentation fault (11)

Any ideas why this would happen? does it have to do with my environment?

lucasrd

More updates:

I did a tail -f /var/log/httpd/httpd.conf

the segmentation fault occurs whether or not I have the phpinfo() call. However, if I omit the call, nothing displays, when I include the call everything prints out as expected but the fault still occurs in the log file...

Anyone know of server dependencies of oci_connect (such as pthreading) that I need to have configured?

lucasrd

My bad...

tail -f /var/log/httpd/error_log

I've been spending too much time at the command line...everything's a blur

Segfaults are Bad Things. Really the only way your code is likely to cause an Apache process to dump core is if it is such a pig for resources that your system can't support it any more (e.g. infinite recursion). That's not the case here!

So my suspicion would be in the direction of PHP itself. A couple of these items look like they may be relevant (there are other experiments you may want to try out, mention of things like environment variable settings, and whatnot); if not, then perhaps a new bug report is in order.

Ok, I finally got it working...

I set ALL the environment variables...apache still seg-faulted...

then downloaded the LATEST version of PHP, re-compiled and installed...that fixed the problem...

Thanks for all the input on this post...
