pravin2006 — Fri, 17 Apr 2009 07:00:50 +0000

I was writing this post after a very long time …. Now here i faced a problem installing phpmyadmin on linux …

Access denied error …..

For those whose geeting while logging through phpmyadmin should include following lines in config.inc.php

$i=0;
$i++;

$cfg['PmaAbsoluteUri']=’localhost/phpmyadmin/’;
$cfg['Servers'][$i]['host'] = ‘Localhost’;

$cfg['Servers'][$i]['AllowNoPasswordRoot'] = ‘true’;

// This will definitely solve the problem ….

How to get first and last record in mysql

pravin2006 — Tue, 06 Jan 2009 14:11:08 +0000

Hey , its very easy . Its just using two queries and a simple UNION…

for simplication , i m diving the query, the first one is

select A.id from (select id from graph order by id asc limit 1) A // this will give the lowest id , similarly

select B.id from (select id from graph order by id desc limit 1) B // this will give the highest id , similarly

Now , joining the two queries with UNION will serve the purpose

select A.id from (select id from graph order by id asc limit 1) A UNION

select B.id from (select id from graph order by id desc limit 1) B // will give two records

+——+
| id |
+——+
| 1 |
| 1078 |

array_multisort in php

pravin2006 — Tue, 09 Dec 2008 08:23:27 +0000

Today i have used array_multisort function of php , its very easy …

I got a array, may be assoaciative example $name_array = (

[0] = array

(

[id] => 1,

[name] = > pravin

)

[1] = array

(

[id] => 2,

[name] = > navin

)

// and so on

)

// for sorting is by name alphabetically , we will use array_multisort();

first we will store all the names from the array in another array

$names = array(‘pravin’,'navin’);

// now we will array_multisort to sott by name

$sort_array = array_multisort($names, SORT_ASC , SORT_STRING, $name_array)

// this will change the sequence of array and return navin first with all details then pravin bcoz , ‘n’ comes before ‘p’

// if we want reverse just use SORT_DESC

Thats all … its easy to use …
