Check whether current time lies between start hour and end hour (PHP)

I started to think of a function in PHP that checks the current time whether it lies between start hour and end hour. This was a task from my boss a couple of weeks ago. He asked this function to write in order to turn down our web application from 900PM to 400AM and display an appropriate message. I googled for a few minutes and compiled the code below:

[dfads params=’groups=-1′]

function checkTime($current_time, $start, $end){
/* $current_time = "9:00 pm";
$start = "9:00 pm";
$end = "4:00 am"; */

$date1 = DateTime::createFromFormat(‘H:i a’, $current_time);
$date2 = DateTime::createFromFormat(‘H:i a’, $start);
$date3 = DateTime::createFromFormat(‘H:i a’, $end);

//echo $date1;
if ($date1 >= $date2 || $date1 < $date3)
return 1;
return 0;

$curTime = date(‘h:i a’);
$curTime = "9:00 pm";
//echo $curTime;
if(checkTime($curTime, "9:00 pm", "4:00 am")==1){
echo "Server Under Maintenance !!
<div style="color: #cc503f; border: 2px solid red; border-radius: 6px; margin-left: auto; margin-right: auto; width: 600px; height: 200px; padding: 10px; text-align: center;">

Eport data to excel using Codeigniter and Oracle (OCI)

Below is a simple code snippet that will help you to export data to CSV/Excel format using Codeigniter and Oracle. Yes, it is obvious that you must have knowledge regarding Codeigniter and Oracle before you proceed further reading.

[dfads params=’groups=-1′]

The code below contains few PHP variables and function calls. I hope that you understand the same in a better way and please give your feedback if you feel this needs.

$sql = "SELECT * FROM your_table_name";
$filename = "Name_of_the_file.csv";
$countRow = functionCountRow();


public function ExportToExcel($sql,$filename,$countRow) { 	

		$output = "";

		$this->epfo_db = $this->load->database('EPFO', true);		

		$stmt = oci_parse($this->epfo_db->conn_id, $sql);


		$ncols = oci_num_fields($stmt);

		for ($i = 1; $i <= $ncols; ++$i) { 			
                    $colname = oci_field_name($stmt, $i);			 			
                    $output .= '"'.$colname.'",'; 		
                $row = oci_fetch_all($stmt, $result); 		

		// Get Records from the table
                    foreach($result as $key=>$val){

		// Download the file	
		header('Content-type: application/csv');
		header('Content-Disposition: attachment; filename='.$filename);

		echo $output;

ORA-24408: could not generate unique server group name

After continuous google for more than 10 hours, I finally came to a conclusion that the problem “ORA-24408: could not generate unique server group name” was not with oracle instanclient or the connection string oci_connect(). The only problem was with the mis-match of the hostnames of the application server defined in /etc/sysconfig/network & /etc/hosts.

[dfads params=’groups=-1′]

After modifying the hostnames in both the file to a single name, the problem was solved.

 $ vi /etc/sysconfig/network

$vi /etc/hosts

$ vi /etc/hosts
#   localhost localhost.localdomain localhost4 localhost4.localdomain4    RHEL65

$service network restart

The above steps helped me save my valuable time. Thanks to the bloggers.

I hope these information would help you too. Best wishes!

How to redirect http requests to https on Debian Linux with Apache Web Server?


[dfads params=’groups=-1′]

Do the following to redirect http requests to https running on Debian Linux with Apache Web Server.

File : /etc/apache2/ports.conf

NameVirtualHost *:80
Listen 80

File : /etc/apache2/sites-availabe/default

<VirtualHost *:80>
ServerName www.example.com
Redirect / https://www.example.com/

<VirtualHost *:443>
ServerName www.example.com
# … SSL configuration goes here

Restart Apache Webserver

/etc/init.d/apache2 restart

Installing and Configuring Commercial SSL on Debian Linux


[dfads params=’groups=-1′]

Note: Please note that commercial SSL certificates require a unique IP address for SSL-enabled sites.

a. Enable SSL for Apache and make a directory named “ssl” inside “/etc/apache2/”

a2enmod ssl
mkdir /etc/apache2/ssl

b. Create a Certificate Signing Request

cd /etc/apache2/ssl
openssl req -new -days 365 -nodes -keyout www.mydomain.com.key -out www.mydomain.com.csr

The above command will create a certificate signing request (CSR) for the site which you’d like to use with SSL. Leave the challenge password blank.
Execute the following command to protect the key:

chmod 400 /etc/apache2/ssl/www.mydomain.com.key

Files for your domain will be created in /etc/apache2/ssl. You may now submit the file ending in .csr to a commercial SSL provider for signing. You will receive a signed file after the CA signs the request. Save this file as /etc/apache2/ssl/www.mydomain.com.crt.
Execute the following command to protect the signed certificate:

chmod 400 /etc/apache2/ssl/www.mydomain.com.crt

[dfads params=’groups=-1′]

c. Get the CA Root Certificate
You’ll need to get the root certificate for the CA that you paid to sign your certificate. You may obtain the root certs for various providers from these sites:
For example, if we downloaded a root cert for Verisign, we would save it to /etc/apache2/ssl/verisign.cer.
d. Configure Apache to use the Signed SSL Certificate.
We’ll add an entry to /etc/apache2/ports.conf for the IP address you’ll be using to host your SSL-enabled site.
File excerpt:/etc/apache2/ports.conf

Listen 443

Replace the above IP address with your dedicated IP Address. Next, we edit the VirtualHost Configuration file i.e. /etc/apache2/sites-available/default in our case.

SSLEngine On SSLCertificateFile /etc/apache2/ssl/www.mydomain.com.crt
SSLCertificateKeyFile /etc/apache2/ssl/www.mydomain.com.key
SSLCACertificateFile /etc/apache2/ssl/verisign.cer

ServerAdmin info@mydomain.com
ServerName www.mydomain.com
DocumentRoot /var/www/
ErrorLog /var/log/apache2/error.log
CustomLog /var/log/apache2/access.log combined

NOTE: You can edit your existing Virtualhost Configuration file (Virtualhost *:80) by adding the above attributes within the Virtualhost tag.

e. Restart Apache:

/etc/init.d/apache2 restart

f. Congratulations, you’ve installed a commercial SSL certificate! You can visit your site with SSL enabled. i.e. https://mydomain.com OR https://localhost/your_website/

Solution to Url Encoded Slashes (%2F) Problem in Apache

[dfads params=’groups=-1′]

I was working on Drupal 6. I had to troubleshoot a site that has a problem in its link. The ugly URL looks like this: http://rcportblair.ignou.ac.in/admin/build/employee/search/result/none/0/none/%252F1

The last argument in the link i.e. %252F is a forward slash automatically added by the Drupal engine which was creating problem while generating result. There are many ways to handle these urls. One way is listed below:

<VirtualHost *:80>
    AllowEncodedSlashes On

This directive may be set in server config file (e.g. httpd.conf OR /etc/apache2/sites-available/default) and may appear inside <VirtualHost> containers to affect certain websites. Using it in .htaccess files is not allowed.

Clean URLs in CodeIgniter and Drupal for Debian based Dedicated Servers

[dfads params=’groups=-1′]

Initially, when my projects were in CodeIgniter I struggled to find out the solutions for Clean URLs. Now, I am working on Drupal CMS and the process for activating Clean URLs are similar as in CodeIgniter.


1. The first step is to add the following code in your .htaccess file.

<IfModule mod_rewrite.c>
RewriteEngine on

# Rewrite URLs of the form 'x' to the form 'index.php?q=x'.

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ project_dir/index.php?q=$1 [L,QSA]

2. Next, for Debian Linux OS edit /etc/apache2/sites-available/default file and add the following script.

<Directory "/var/www/project_dir/">
RewriteEngine on
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ project_dir/index.php?q=$1 [L,QSA]

3. If you are using CodeIgniter, the above two steps are done but for Drupal sites, visit the following link from your Drupal CMS Admin: http://your_site/admin/settings/clean-urls. Select the Enabled radio button & click on save.

Congratulations, You have activated Clean URLs for your websites.

Apache is running a threaded MPM, but your PHP Module is not compiled to be threadsafe. You need to recompile PHP.

[dfads params=’groups=-1′]

After installing Apache2, MySQL & PHP on Debian wheezy 7.1, I tried to reboot the apache server. It showed me the following error.
Starting web server: apache2[Fri Dec 27 11:29:16 2013] [crit] Apache is running a threaded MPM, but your PHP Module
is not compiled to be threadsafe. You need to recompile PHP.
Pre-configuration failed
Action 'start' failed.
The Apache error log may have more information.

So I searched through the internet to recomplie the PHP Source. But none of the tutorials were best and feasible.

Finally, after long try I found the command below that helped me to run the apache and PHP along.
apt-get install apache2-mpm-prefork
