PHP Warning: strstr(): Empty needle in

[frank18]

Just checked the logs of a client site - ZC 1.5.4 - and found 32 identical (...except for the time) entries in the logs folder - all in the space of about 2 minutes:

[28-Jan-2015 19:56:38 UTC] PHP Warning: strstr(): Empty needle in /home/[account_name]/public_html/includes/functions/functions_lookups.php on line 712

That line reads

case (strstr(EXCLUDE_ADMIN_IP_FOR_MAINTENANCE, $_SERVER['REMOTE_ADDR'])): 

Checked the admin logs for that date - nothing extraordinary.... site was not down for maintenance.

Never had this error previously. Could anyone shed a light on this please....

Cheers / Frank

$_SERVER['REMOTE_ADDR'] can be empty, which causes the error

I think you can suppress the error with @

case (@strstr(EXCLUDE_ADMIN_IP_FOR_MAINTENANCE, $_SERVER['REMOTE_ADDR'])):

or clarify the case condition

case (!empty($_SERVER['REMOTE_ADDR'])&&strstr(EXCLUDE_ADMIN_IP_FOR_MAINTENANCE, $_SERVER['REMOTE_ADDR'])):

Thanks - but suppressing the error is not much good to me, I would like to know the reason for this error.

You probably have no value set for you admin ip under configuration->maintenance

Yes, an IP is set, the field is not empty

Nah, it wouldn't be that. The error message is "PHP Warning: strstr(): Empty needle", which means that it's the $_SERVER['REMOTE_ADDR'] variable being set.

Why it's not being set is something I can't answer, but as SignTorch suggested, suppressing the error is probably the easiest 'fix'.

Addendum:

That should have read:

It's the$_SERVER['REMOTE_ADDR'] variable NOT being set.

ps. Does anyone else experience lockups when trying to edit a post or is it just me? Doesn't happen all the time, but often enough that its become a real headache.

Yeah, I guess so - BUT the question still remains: why is the error happening, is it a bug in the coding -- or what??
