Re: [PHP] Array question
Mike,
See entire function under topic Array question - maybe UTF?...
I am trying to change accented characters to their equivalent without accents.
And yes, the arrays look fine after var_dump()...

Please show a little more code, as it looks to me as though this should work
how you think it should.
Specifically: how do we know what is in $c? how do you know the array_search
works? how do you know $n is only getting 'a', 'b', or 'c'? (Hint: var_dump()
is your friend!)

Re: [PHP] How to run one php app from another?
I don't know if you solved this already, but I use it to redirect to
different pages depending on whther the user is logged in or not.
Something like header(location:/page/?p=login); works fine. You were
on the right track.

Hi gang:
This seems like so obvious a question, I am reluctant to ask.
In any event, I simply want my php application to run another, like so:
switch (option)
{
case a:
run a.php;
exit;
break;
case b:
run b.php;
exit;
break;
case c:
run c.php;
exit;
break;
}
I know that from within an application I can run another php application via a user click
(.e., button), or from javascript event (onclick), or even from cron. But, what if you
want to run another application from the results of a calculation inside your main
application without a user trigger. How do you do that?
I have tried header(Location: http://www.example.com/;); ob_start(),
ob_flush() and such, but I can't get anything to work.
Is there a way?
Thanks.

Perfectly doable in PHP. Just have the form action go to a new php script and do your logic, then use header(location:...) to redirect.

Re: [PHP] Preventing double-clicks
Jay,
I use a technique to prevent hitting the back button and
resubmitting data. I use a 2-script process, one with the form and
submit button (I set a session var here), and a second form (the
action script). The action script makes sure the session variable is
set, processes the info, then clears the session var. If the session
var is not set, an error is displayed.

I am going to do some thinking (typing) out loud here because I need to
come up with a solution to double-clicking on a form button issue.
The steps are;
1. Fill out form
2. Click 'Submit'
3. Data gets stored (including unique data and time stamp data in this
casewhich should work out well)
If the process sees the unique data and a timestamp sometime within the
last minute it should ignore the subsequent attempt.
4. A reply is returned to the user based on the first click. The data
returned to the user would be different for each click, that is why this
is so important. The first data returned is the correct data.
My confusion is in this (as I have mentioned in the past couple of
weeks, most of the confusion is as a result of a lack of rest, which
leads to not thinking clearly, which leads to me feeling ignorant); upon
the second click, where I check to see if the data has been entered and
find that it has how do I get it to return the data back to the user. I
think I see it now..let's see.if I;
Select * from foo where data is what it is and time is within last
interval that I decide upon;
if(1 == mysql_num_rows(that query up there)){
get that data for return to the user;
} else {
Insert data, do calcs, return data back to user;
}
Does that look reasonable, or am I missing something?
Thanks for any insight!

# Loop through each POST'ed value and test if it contains one of the
$bad_strings:

foreach($bad_strings as $v2) {
if(strpos($v, $v2) !== false) {
log_bad_request();
header(HTTP/1.0 403 Forbidden);
exit();
}
}
}
# Made it past spammer test, free up some memory and continue rest of

As I can see most of the spam messages are in Chinese / Japanese.

AFAIK PHP lists use some home-grown moderator so doing this should be an easy task. Of course that may affect some legal users that have such characters in their signatures, but in this case it sounds reasonable just to reply with an email explaining blocking policy so any legal user will know what to do to get his message go through the moderator.
