PHP :: MySQL Result To Real Array In Function

Replacing Array With Mysql Result
I wanted to repalce the following line of code $data = array(40,21,17,14,23); with

for($i=0;$i<$numrows;$i++)
{
//print(mysql_result($result,$i,2));print("<br>");
array_push($data,mysql_result($result,$i,2));}

where mysql_result($result,$i,2) is the value and when i print it displays the values. But $data array is the Y axis value for drawing a chart. Here I wanted to replace the hard coded value with values from mysql but the second code does not function. Does anybody have idea how can I replace the $data array or what may be the problem with my coding The first one works but the second one does not work but in both cases it does not display any error.

Sort A Mysql Result According To A Php Array
Hi everybody !
I have a question for the gurus ;+)
I have to arrays :

PHP Code:

$id = array(45,9,21);
$pos = array(3,1,2);

I select in my mysql table using the ids :

PHP Code:

$sql = "SELECT * FROM MyTable WHERE id IN(".implode("",$id).")";

and I now want to sort the result according to the $pos array.
Is there a way to do this directly in mysql ?
If not, what would be the smartest way to do it in PHP ?
Because I would prefer NOT to do the following :

PHP Code:

while ($t = mysql_fetch_array($ret)) {
Â Â Â Â $a_field1[] = $t["field1"];
Â Â Â Â $a_field2[] = $t["field2"];
Â Â Â Â $a_field3[] = $t["field3"];
Â Â Â Â $a_field4[] = $t["field4"];
...
}
array_multisort($pos,$a_field1,$a_field2,$a_field3,$a_field4)

I fear it could be a very time consuming process when there is a lot of results and a lot of fields. But may be the no other solution...

Thanks

Assign MySQL Function Result To PHP Variable
I know to use: mysql_fetch_row($result) to convert a row from a SQL query result set into an array for use with PHP. but in the case of SQL queries that return one value, such as calls to MySQL functions, is there another PHP mysql api function I should use.

For example, right now I use a "workaround" technique from PHPBuilder:
$result=mysql_query("SELECT COUNT(*) FROM tablename");
list($numrows)=mysql_fetch_row($result);

Rather than using this "workaround" code is there a way to simply assign the result of the MySQL function query to a variable.

$result=mysql_query("SELECT COUNT(*) FROM tablename");
$numrows=mysteryfunction($result);

If Result Of Mysql Query Is Only One Row/column, Why Use An Array?
If I'm doing a very specific select statement, which I know will only ever return one value, can I get that resulting bit of data without storing it in an array or object?
If not, is mysql_fetch_array() the fastest method for getting this one value?

Changing Array Format From Result Of MySQL
here is what MySQL returns in a visual way..

game_id | team_id | stat_id
1 | 1 | 1
1 | 2 | 3
1 | 3 | 7
1 | 3 | 6
2 | 1 | 1
2 | 4 | 3

in records with the same game_id, there will be no repeating team_id
in records with the same team_id, there will be no repeating stat_id

so, after I got the query, I made them into this format

Can I Put A Mysql Query Result Directly Into A Multidimensional Array?
I have two joined tables:

Departments - which contains the department description and a key
Positions - which contains position data

What I'm attempting to achieve is to display the department title in one table cell and then list all the positions associated with that department in the cell under neither the title. I need to generate a table two column table with as many rows as required, depending on the number of departments, which is dynamic.

Do this I'm trying to turn the result of my SQL query into multidimensional array e.g. dept = VioP positions = "designer", "engineer" etc, which I can do then use to generate the table.

I've done a search on the forum and looked around the manual and I'm stumped on how to achieve this, a point in the right direction would be greatly appreciated. The query I'm using is below. PHP Code:

Making Mysql Result Into Multi-dimensional Array
My php problem is I want to make the result of 3 tables linked through foreign keys into a 3-dimensional array that reflects their relationship without repetition and without having to call the database more three times.

I know I'm doing a couple of things wrong, one thing for instance is initializing a variable at the end of the loop to remember the previous value s that it does not repeat itself, surely there must be a more elegant way to go about this, but I'm lost and I've been stuck on this all day. Code:

A Real Challenge For Real PHP Programmers
<?php
/*
A challenge to every PHP programmer.The one who's gonna solve this
problem would be deemed as

PSP(PHP Supreme Programmer).The problem is this : You have to write a
script that displays a list of

categories and subcategorieslike this one:

<select name="category">
<option value="1">Main</option>
<option value="2">Main > Computers</option>
<option value="4">Main > Computers > Hardware </option>
<option value="8">Main > Computers > Hardware > PC</option>
<option value="7">Main > Computers > Hardware > Mac</option>
<option value="9">Main > Computers > Hardware > Atari</option>
<option value="11">Main > Computers > Hardware > PC > History of
Pc</option>
<option value="">etc...</option>
</select>

The categories and subcategories details are stored in these two
tables in a MySQL database.
-categories : the categories names and ids.
-cat_relations : the relations between categories.It shows which
subcategory belongs to which category.
The belongings between categories can go very deep and the number of
categories is unlimited. This script will create the two tables and
fill them with sample data. All you need to do is to change the four
variables below. You can send the script back to this email :
yasbergy@yahoo.com.
*/

//Here starts the script. Please change the values of these variables
to fit your settings
$user = "prospective_PSP";
$database = "db";
$server = "localhost" ;
$pwd = "" ;
//Connection to the database that you created
mysql_connect($server,$user,$pwd) ;
mysql_select_db($database);
//Creation of the two tables : categories and cat_relations
$categories = " CREATE TABLE `categories` (`id` INT not null
AUTO_INCREMENT, `name` VARCHAR(100) not null , PRIMARY KEY (`id`),
INDEX (`id`), UNIQUE (`id`)) comment = 'The categories details' ";
mysql_query($categories) ;
$cat_relations = "CREATE TABLE `cat_relations` (`id` INT not null
AUTO_INCREMENT, `daughter_id` INT not null, `mother_id` INT not null ,
PRIMARY KEY (`id`), INDEX (`id`), UNIQUE (`id`)) comment = 'Which
category is the daughter of which category'";
mysql_query($cat_relations) ;

//Filling the two tables with sample data
$cats = array('Main','Computers','Countries','Hardware','S oftware','Programming
languages','Mac','PC','Atari','Winamp','History of the
PC','IBM','Components','High
level','USA','NYC','LA','Manhattan','India','Winzi p');
for ($i=0;$i<count($cats);$i++){
$sql = mysql_query("insert into categories (name)
values('".$cats[$i]."')");
}
mysql_query("insert into cat_relations (daughter_id,mother_id) values
(2,1),(3,1),(4,2),(5,2),(6,2),(7,4),(8,4),(9,4),(1 1,8),(12,8),(13,8),(10,5),(20,5),(14,6),(15,3),(16

//Now you can have a look on them through phpMyAdmin

Real Life Examples Of Mysql+session_set_save_handler
In my test setup using my own session handlers with session_set_save_handler and mysql, the session handler opens and close mysql connections.

But what if my page also requires some mysql queries? Should I open a new connection or use the already opened one (opened by the session handler)?

I have made it a good practice to close a connection after a query but if I do it with only connection open no session data will be written to my mysql table.

I have seen some scripts using persistent connections but are not sure what would be the best for a real world environment.

Array Explode Problem Result In A 6 Item Array
I have the following:

$basket_containers = explode('Ã‚Â¦', $BB_Basket);

print_r($basket_containers);

This results in

Array ( [1] => APL6007,2.00 [2] => AVX8900,1.00 [3] => ARCAV500,1.00 )

Now when I try to explode further with

$basket_items = explode(',', $basket_containers);
print_r($basket_items);

This results in

Array ( [0] => Array )

This should result in a 6 item array. Any ideas what I'm doing wrong?

Result Of Array Diff()
I'm successfully able to compare two different arrays with array_diff(). The result of this comparison is, of course, assigned to a new array. Unfortunatly (for my purposes) the array indeces of the resulting matching items are retained, yet empty:

[a][b][empty][d][empty][empty][g] - and so on.

I'm wondering if there's a built-in function that would sequentially assign all non-empty index items of my array_diff() result to a second array, like:

[a][b][d][g]

I know I can do this with a loop, but am wondering if there's already a function to handle this.

Using The Function Prevents Accessing The Result Of The Match.
I don't know if this is possible, but it should be. However, it doesn't seem to be working for me. how I can get it to work:

I use :||: for my delimiter for str_replace, etc.

When replying, the new PM is appended in front of the existing chain of replies, thus the same table entry is used and updated each time. Problem is in storing the sent date, and providing time zone and format adjustments:

$string='This is the message that was sent on :|1161850848|:'

$newString=preg_replace('/([0-9]*)/',format_time(adjust_time('${1}')),$string);
// the result of this is as if ${1} = 0

$newString=preg_replace('/([0-9]*)/','${1}',$string);
// returns 'This is the message that was sent on 1161850848'

It seems that using the function prevents accessing the result of the match.

Refreshing Cache Through Php Header Function Yields No Result?
I am building a website for a client. He wants a login page with a "Your account" page for his clients. I am using a combination of javascript and php.

Upon succesful login $_SESSION variables are set to 1.
example: $_SESSION['logged']= 1;

If the client logs out due to idle time or pressing 'logout' these values are set to zero.
example: $_SESSION['logged']= 0;

Upon loading of "your account" and any of its sub-pages, that page checks $_SESSION['logged']. If the value is zero it redirects automatically back to the login page. Providing oppertunity to log in again if you wish.

The checking of $_SESSION['logged'] is supposed to redirect even if the client has logged out, but has pressed "back" on the browser to try and see a login page.

The page does not do this. Pressing "back" reveals the page. Interacting with the page or pressing "refresh" THEN causes it to redirect.

I need the page to auto-redirect, not show. I am aware that it is the page being cached and keeping those values until you interact with it. I have fully tested the header function in php. Using 'must-revalidate' & 'no-cache' and other version! (most info from php.net).

I get no errors when testing the pages, so my code is correctly spelled! But there is simply no reaction by the page, it just does what it does, which is not what it is supposed to do?

I ask for experience! Is there a specific way of doing the header functions? Perhaps it must be placed in a specific place in the page? And how can i check that the page is actually using the functions and not just moving over them with no action taken?
