This is because of your mktime() call. You're trying to get the zeroth day of 
the month, which is the last day of the preceding month. Using mktime(0, 0, 0, 
$i, 1) instead should give you the desired results, assuming you do start at 1, 
and not 0 as you have in your code.

You'r specifying day 0. Which actually is in december. It is an optional
argument. So you can specifify mktime(0,0,0,$1) instead.

I wouldn't really use a while statement for this, but a for loop instead, as it 
needs less code:

<?php

echo "<select>";

for($i =1;$i<=12;$i++)
{
     $dateformat = date("M", mktime(0,0,0, $i,0,0));

     echo <<<HTML

     <option value="$i">$dateformat $i</option>

HTML;
}

echo "</select>";
?>


The other code was starting from 0 and going to 12, which is 13 months! Also, 
you had the variable being compared as a string, which will work in this 
particular case, because php will convert $i to a string before each comparison 
in the loop. While it works in this case, its best practice to use the variable 
type you need to avoid unusual behavior.

The mktime function is unusual in that indexes for months start at 1 and not 0 
as you might expect, but it does indicate that on the manual pages.

Subject: [PHP] odd while behavior...
To: "PHP General list" <[email protected]>

Okay so I'm just playing around with some stuff trying to learn more  
and expand my knowledge and I ran into something I don't understand...  
Take the following code:

<?PHP

echo "<select>";
$i ="0";
     while($i <="12") {

     $dateformat = date("M", mktime(0,0,0, $i,0,0));
     $month = mktime(0,0,0, $i,0,0);
     //echo date("M", mktime(0,0,0, $i,0,0));
     //echo "<br>inside while<br>";
     echo <<<HTML
     <option value="{$i}">{$dateformat} {$i}</option>
HTML;
     $i++;
     }
echo "</select>";

?>

which does display a select drop down box with the month's in it...  
But on my test server it starts the display at december... With  
setting $i = "1" i would have thought it should start at january?

Any ideas on what I missed? :)


Thanks for looking! :)

Probably a PHP compilation problem.
The message seems refer to the headers (libmysql.h) used in the ./configure phase of the building process.
It seems like your PHP version was compiled using a MySQL 5.0.11 version header, while your connecting to a server running MySQL 5.1.51, Have you upgraded your MySQL recently? are you using the MySQL server on the same machine that runs Apache/IIS/etc.. and PHP? 

Sorry for the "Italianese" english :)

Can anyone help me with this error message and explain how to correct
the mismatch?

PHP Warning:  mysqli_connect() [<a href='function.mysqli-

minor version mismatch. Headers:50051 Library:50151

It would help if you provide the platform and platform version:
Windows, Linux, Mac, FreeBSD, or other variants.

And also the PHP version you're using.  Did you compile PHP yourself or

use

a distribution?

Tommy


Forgot to mention this earlier... too hasty on the send button ... lol.
Since it's only a warning and you are able to connect, run [1] & [2] to see 
what do you get.

You still haven't answer the question of what platform? FreeBSD? Linux? Mac?
Windows?  And what is the platform version?

How did you uninstall?  Using the OS's software/package manager such package
on FreeBSD, yast on some Linux, add/remove programs on Windows, etc.?  Did
you compile any of it - MySQL or PHP - yourself?

This just means that there's a mismatch within the PHP.  If you compiled
from source for any of it, PHP's MySQL & MySQLi extensions depends on the
MySQL headers and client library.  Thus, MySQL client has to be compiled
first before you can compile the PHP's MySQL/MySQLi extensions.  This
applies to all platforms if you're doing your compilation from source.  If
you didn't compile any of it - both MySQL and PHP - then the problem lies
within your OS's software/package manager.  Without knowing what you're
using, we can't really tell what happens.  Some Linux distributions do
things differently.  I'm not well versed in Linux but many others here on
this list can help you with it.  I suggest you 'uninstall' both PHP & MySQL.
Then reinstall MySQL 1st and PHP 2nd.  Also, just a bit curious... where did
you get the MySQL & PHP?  I hope directly from the official source... ;)

Forgot to mention something, please don't top post.  It makes hard for
others to follow the thread.

Are you running PHP with IIS or Apache?  If with Apache how are you running
PHP as, CGI or module?  Since you're using official distributions, you'll
have to use PHP VC6 TS build (if not using as CGI/FastCGI) for Apache [1].
If you're running PHP with IIS, you'll have to run NTS build for FastCGI
[2].

Hello everyone,
For the past while, I've been working on a class for reading in, modifying and writing out NBT-format files. This particular format is used for the game Minecraft, as some of you may know.
Attached is my work so far on this, which is coming close to being a working solution to reading the files in. As well, attached is an example NBT for testing the script.
The specification for the NBT format can be found at http://www.minecraft.net/docs/NBT.txt.
The issue which I'm having is that PHP's pack and unpack function for binary data does not seem to be complete. Or, at least, it's missing certain functionality which is necessary for what I'm trying to do.
It may be a matter of misunderstanding on my part, but I would have expected the pack and unpack function to be able to handle every combination of endianness, signing and machine-specific sizing of each type.
Currently, I'm stuck in reading in the TAG_INT type of the NBT format, which is a 32-bit signed short, big-endian, as per the specification. There does not seem to be a packing format code for this data type.
How might I go about this? Am I simply missing something about binary data, or is PHP's pack/unpack functionality indeed lacking? And, if the pack and unpack functions are indeed lacking, is it possible to handle binary data without those functions? 

Thanks,
Justin Martin

Dear List -
Here are some questions, which I am sure are trivial, but I am a newbie, and cannot find the answers online....
I cannot get the following to work. In my Firefox [Iceweasel] browser, I enter the following URL: [w/ the http] 

 localhost/CreateNew.php All I get is a blank browser screen.

The code  contained in the file CreateNew.php is:

/*
 *  Create Database test22
 */
 <html><body>
<?php
$cxn = mysqli_connect("$host",$user,$password);
echo    "Create database test22;"
echo    "Create table Names2
(
        RecordNum Int(11) Primary Key Not null default=10000 auto_increment,
        FirstName varchar(10),
        LastName varchar(10),
        Height  decimal(4,1),
        Weight0 decimal(4,1),
        BMI decimal(3,1)
        Date0 date
);"

echo"   Create table Visit2
(
        Indx Int(7) Primary Key Not null auto_increment,
        Weight decimal(4,1) not null,
        StudyDate date not null,
        RecordNum Int(11)
);"

        $sql= "SHOW DATABASES";
?>
</body></html>

If I search for test22 or Visit2, nothing is found.
I would also like to be able to add data to a table, using PHP, which I can do in MySQL as: load data infile '/home/ethan/Databases/tester21.dat.' replace into table Names fields escaped by '\\' terminated by '\t' lines terminated by '\n' ; 

Thanks in advance.
