Hi,

MySQL database, I have a table, which is HEAP (memory) type and I found

insert new entry it gives me an error that the table is full.
The question is: How can I increase this limit?
Only the mysql documention or lists will be able to answer that.

So you know it's off topic, yet you're going to ask anyway.

Well, you could read the *MySQL* manual. You could search Google. You
could search the archives for the *MySQL* mailing lists. If none of
that bears fruit, you could post this question on the *MySQL* mailing list.

PHP is indeed working. If I use METHOD=GET instead of POST, the script works
without any issues. Here is the test script I'm using:
<html>
<title>test script</title>
<body>
<?php
//If the user wants to add a joke
if(isset($_GET['addtext'])):
You're checking for a get string here, not a post string. So it will
never get into this part of the code.

I have tried _POST here, and when its then that I won't be able to get into
the part of the code that I want to get into. $addtext is passed through an
HREF tag, not through the form.
I think I have reached the limit where I need to use a debugger to get any
further. I just installed Gubed, and currently reading the documentation.
Once I can start debugging the script, I will be able to know what and where
exactly are things going wrong.

Sorry, missed that bit.
First step before using a debugger, add:
echo "<pre>"; var_dump($_POST); echo "</pre>";
somewhere in your code and go from there.

[/snip]
The form action should be $_SERVER['PHP_SELF']. Here case
matters, since this is a string and not a variable name.
If action is empty, I believe browsers simply send the request
to whatever URL the page was accessed at. Since you're already
at a GET (with ?addtext), the POST request actually includes
both the GET and the POST, so the the form is shown again.
Just var_dump $_GET and $_POST and you'll see what's happening.

The most likely explanation is that there is something wrong with your
script or with your form. It would help if you showed the code (a minimal
test case by preference) you are trying to use.

Hi all,
are there any security concerns with uploaded images?
My thought is that it wouldnt be too hard to have some kind of script
masquerade as a gif file, and perhaps cause damage.
I cant find anyway to check a file really is a gif/png/jpg (i assume the
mimetype available in $_FILES could be spoofed).
I'd welcome any thoughts in general on this, but specifically if anyone
has experience/knowledge in this area and can point me in the right
direction.
Check the file extension and the mimetype, make sure they are both
valid.. or as someone else suggested, use getimagesize on it - if that
returns false or empty then it's not an image.

Ok thanks guys. I'll do extension and mime and getimagesize() before
saving/using them.

is there a way to upload large files (e.g. 15mb) without changing the
default settings in php.ini***?
According to this page:
http://www.php.net/manual/en/ini.php#ini.list
You can do it with a htaccess file. See comments at the bottom.
Preferably by using php, but if not is there another web tech (e.g. Java
applets) that will allow me to do this?
Sure. Python, ruby, java, perl, whatever you like.

Why don't you want to change the php.ini values if you legitimately want to

Depends on the size of the file. If it's 10M, php will be able to
handle it. If it's 100M, teach them to use ftp - it'll save you so
many headaches.
You can write a java applet if you like but how you do that? Don't
know - you'll have to find a java list :)

Subject: [PHP] Wierd ass code...
Hey,
Been reading some other code that I got from the net,
and have come across some wierd looking code, would
appreciate it if someone could explain it to me:
$hits = array();
$bytes = array();
$blocked = array();
$baps = array();
$bapm = array();
So far so good.... then further down:
// Add to the running totals
@$hits["$username|$subnet"]++;
@$bytes["$username|$subnet"]+=$byte;
@$baps["$username|$subnet|$this_second"]++;
@$bapm["$username|$subnet|$this_minute"]++;
What kind of arrays are the above? I have never seen
nor worked with arrays like them before.
If you can point me to a particular place in the
manual or a few URLs too would be appreciated.
Thanks,
Ryan
I don't think there is nothing special with the arrays, he is just
coding some information into strings, with the vertical bar as
separator, and using this as the keys to several arrays where he is
collecting some statistical information, such as (it would seem to me)
- number of hits by user and subnet
- number of bytes by user and subnet
- number of hits per user and subnet per second
- number of hits per user and subnet per minute
I would assume that the variables $this_second and $this_minute are
absolute numbers counted from a particular time, not seconds from 0
to 60 within the minute. Likewise for the minutes.
I assume that the @ in front is to avoid the error of trying to
increment a value that is not yet set.
I guess that this same thing could have been achieved with
multidimensional arrays but either concatenating the variables into a
single string is faster or some other reason that makes sense for the
application, such as being able to sort by keys in just one operation.
Satyam
Of course, another possibility is that the author does not know how to
handle multidimensional arrays (just to say it before anyone else
points an obvious alternative)
Satyam
Hi!
I don't think the author does not know how to handle multidimensional
arrays. I thought the author was more concerned about performance than
other issues people like as coding "beautifuly"... Maybe author's
approach is weird, but its twice faster in the worst case!!
Sure the author only needs to loop the whole array and doesn't need
multi-dimensional approach... 'cause its a lot faster to iterate once
the array is filled!!
Look at the test I've done (below) its seems filling multi-dimensional
arrays is n/2 faster than single dimension, but then when you need to
read the array data, a multi-dimensional approach is always worse than
n*6!! so the total time for setting & getting the data is about n*2 in
the worse case... Repeating the same operation multiple times, the
multi-dimensional approach always gets worse performance ??, but
single-dimension stays performing in a linear way. I think that's really
interesting!!
Perhaps there are better approaches for iterating over multidimensional
arrays, but that's what I got in 5 minutes coding. I'd like to hear your
suggestions about if the author code really worth the pain when
performance makes sense.
Attached results and code. (tested on PHP 4.3.4)

hi list -
am wondering what approaches people take for multilanguage sites? were
working on a CMS system and need to have the UI / links show up in
many languages and be easily localizable by people.
we're using smarty, so one approach is to use smarty config files and
then smarty tags for all the items.
_TOP_MENU_BTN= "return to top menu";
is there a big performance hit to this? this means replacing a lot of
items in each page, each pass.
the other way is to just localize inline in the template files
themselves, but this means if a design changes all the lang templates
for each lang have to be updated... :(
another way is to have a huge define file
define("_TOP_MENU_BTN", "return to top menu" );
is this a LOT faster?
Also i am looking for some way to manage the strings during
translation, to make sure as things get added to say the english UI
that its easy to track whats missing from the translations. i guess
well have to build a simple spreadsheet like GUI but i was wondering
if anything is already available.
I guess there is also a gnu gettext extension, but it doesnt seem
widely supported or avail for windoze.
tx for any other suggestions!!

suitable caching/compiling should be used to avoid translation on each pass -
maybe using a precompiler plugin - I haven't figured out a decent way of doing
this
myself yet.

creating constants is SLOW. using the apc extension constant related
functions is a great way of speeding this up. outputting the
constants is comparative fast.

I have no idea about gettext on windows - personally I would never
use windows for a production webserver anyway.
I'm currently working on a stand alone 'plugin' type application using gettext
that can scan (using tokenize) & manage a projects files, retrieve all
translatable
strings dump them in a DB (with an editing interface for translators) and
finally
generate the binary .mo files for the project ... it requires that all strings
in
the project are translated via the 'gettext()' function (or it's alias '_()').
in the longterm gettext is the superior method and a solution that allows you
to use
it AND manage the translations is the way to go IMHO.

Without seeing all of the code, we can't tell anything from that.
