For create a virtual host in ubuntu please follow the below step by step process.
Virtual host name is : “local.dating”
Document root for that virtual host : “/var/www/dating”
1. Create a file with name of your virtual host(name you want for your virtual host like “local.dating”) on “/etc/apache2/sites-available/”.
2. Write the following code on that file :
/*******************************************************************/
#
# local.dating
#
ServerName local.dating
#ServerAlias www.sitename.com
DocumentRoot /var/www/dating
CustomLog /var/log/apache2/local.dating-access.log combined
ErrorLog /var/log/apache2/local.dating-error.log
/*******************************************************************/
3. Now you have to enable this virtual host. To do so please go to your terminal and type following command
sudo a2ensite local.dating
To disable a virtual host use following
sudo a2dissite local.dating
where local.dating is the name of the virtual host you want to enable/disable.
4. Now apache is almost ready to restart, but before doing so, we must inform our linux system that dev.example.com and www.dev.example.com are not to be looked for on the net, but on the local machine instead.
To do so, simply edit “/etc/hosts” and add the new host names at the end of the line beginning by 127.0.0.1, which is localhost like below :
127.0.0.1 local.dating
5. And now we are done, simply reload apache by following command :
sudo /etc/init.d/apache2 reload
Open your web browser and enter the following address local.dating. Magic, it runs the same as when you were using http://localhost/dating but it is far more usefull when devellopping a web service and want to be able to develop applications on your machine just like it is where the real web site.
You should now configure the sources for apt.Once that’s done you can upgrade your system to get the latest updates.
- $ sudo -s
- $ aptitude update
- $ aptitude upgrade
You can also do the other steps on this page to configure the network, ssh etc.Only difference is that I prefer aptitude over apt-get since it’s apparently better with dependencies….
Now we’re ready to install the software needed by SugarCRM:
- $ aptitude install php5-imap php5-curl unzip
And set the right permissions….
- $ chmod -R 777 /var/www/sugarcrm
- $ chmod -R 777 /var/www/sugarcrm/cache
- $ chmod -R 777 /var/www/sugarcrm/custom
- $ chmod -R 777 /var/www/sugarcrm/data
- $ chmod -R 777 /var/www/sugarcrm/modules
- $ chmod -R 777 /var/www/sugarcrm/config.php
Now we have to edit the default php.ini for SugarCRM, so open it in your favorite editor.The path to the php.ini file is: /etc/php5/apache2/php.ini
- $ nano -w /etc/php5/apache2/php.ini
Find : allow_call_time_pass_reference = On
Change : allow_call_time_pass_reference = Off
Find : memory_limit = 8M
Change : memory_limit = 32M
Find : upload_max_filesize = 2M
Change : upload_max_filesize = 10M
And finally we restart apache for the changes to take effect.
- $ /etc/init.d/apache2 restart
That’s it, you should now be able to go to the web installer of SugarCRM.Just point your browser to http://server-ip-address/(sugar crm directory)/ which should automatically load http://server-ip-address/(sugar crm directory)/install.php
And go on…
PHP have rich set of functions to solve real time problems in programming and web development.. thanks to Rasmus Lerdorf
eval — Evaluate a string as PHP code
A SET datatype can hold any number of strings from a predefined list of strings. The ENUM datatype restricts to a single member of the set of predefined strings, the SET datatype allows to store any of the values together, from none to all of them.
CREATE TABLE phpsolutions_set (
name SET(’lamp’,’web’,’linux’,’joomla’)
);
CREATE TABLE phpsolutions_enum (
name ENUM(’lamp’,’web’,’linux’,’joomla’)
);
If we want to fill the html select box with these two tables…
SHOW COLUMNS FROM phpsolutions_set;
> set(’lamp’,’web’,’linux’,’joomla’)
SHOW COLUMNS FROM phpsolutions_enum;
> enum(’lamp’,’web’,’linux’,’joomla’)
now based on column type set list of string values from mysql to php array…
<?php
…….
// if column type is set
$arr = “\$set=”.str_replace(”set”, “array(”, $column[‘Type’]));
eval($arr);
// if column type is enum
$arr = “\$set=”.str_replace(”enum”, “array(”, $column[‘Type’]));
eval($arr);
…………..
?>
Use $set PHP array to fill select box….
Geocoding (finding latitude/longitude for street addresses), Geotagging (tagging media with latitude/longitude coordinates), and Geolocation (finding latitude/longitude of computer with IP X-Forwarded-For). There are some options to install on linux environment:
# wget http://geolite.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz
# gunzip GeoLiteCity.dat.gz
# sudo mkdir -v /usr/share/GeoIP
# sudo mv -v GeoLiteCity.dat /usr/share/GeoIP/GeoIPCity.dat
Install geoip with php5
# sudo apt-get install php5-geoip (ubuntu)
# sudo yum install php5-geoip (centOS)
# sudo pecl install geoip (with PECL)
In Windows environment we have to add extension “php_geoip.dll” with PHP
Download extension from here : http://blog.phpsolutions.co.in/php-5.2.1_geoip-w32.zip
Copy “php_geoip.dll” to xampp “php/ext” .. add a line in php.ini
“extension=php_geoip.dll” and restart xampp
This extension will work on development system using Windows, Apache 2.2.3 and PHP 5.2.10. check “geoip” with phpinfo() module is loaded.
We can
<?php
$record = geoip_record_by_name('www.phpsolutions.co.in');
if ($record) {
print_r($record);
}
?>
Array
(
[country_code] => US
[region] => CA
[city] => Marina...
[postal_code] =>
[latitude] => 23.9776792798
[longitude] => -128.435796741
[dma_code] => 867
[area_code] => 400
)
<?php
$result = geoip_record_by_name('78.aaa.yyy.xxx');
var_dump($result);
?>
There is alternative PHP version of the GeoIP API from MaxMind,
but this solution is quite slow on servers. MaxMind uses MaxMind database to display geo locations.
Have you checked my previous article on cronjobs…
http://blog.phpsolutions.co.in/tag/crontab-command-line/
To run cronjob per second you have to execute crontab/cronjob per minute and then have to run task in cron file per second using PHP function time_sleep_until().
<?php
$start = microtime(true);
for($ii=0;$ii<60;$ii++)
{
//……………………….
/// here is the tasks which need to run per second…
//……………………….
time_sleep_until($start + $ii + 1);
} // end for
if (!function_exists(‘time_sleep_until’))
{
function time_sleep_until($future)
{
if ($future < time())
{
trigger_error(“Time in past”, E_USER_WARNING);
return false;
}
usleep(($future – microtime(1))*1000000);
return true;
}
}
?>
Have you checked my previous article on CakePHP…

Yii (Yes, it is) — a high-performance component-based PHP framework best for developing large-scale Web applications. Yii have features, including MVC, DAO/ActiveRecord, I18N/L10N, caching, jQuery-based AJAX support, authentication and role-based access control, scaffolding, input validation, widgets, events, theming, Web services, and so on. Written in strict OOP, Yii is easy to use and is extremely flexible and extensible.
YII Features:
– Magic overloading functions
– Lazy loading
– Authentication / Validation
– Widgets (sharing extensions)
– Yii console
– High-performance
– Templates
– MVC Push-Pull
– RBAC
– Test Case (PHPUnit, Selenium)
– EAccelerator
– jQuery
– Zend support
I am currently reviewing YII in comparison with CakePHP … Keep in touch 🙂

RESTClient is an application use to visit and test RESTful services.
REST (Representational State Transfer) is the model of the Web to consume web resources. The browser makes a request to a URL and receives a response. The request may be a GET or POST (or a PUT, DELETE, or HEAD) and the response may be anything HTML, Image file, PDF, XML, JSON etc.
