Small example:

$itemList = explode(",", $itemList);

echo count($itemList);

$itemList = array();
$itemList = explode($delimiter, $imgURL);
foreach($itemList as $item)

  echo"<img src='".$item."' longdesc='".$item."'/>";
}
?>

How to remove index.php from codeigniter in Raspbian....... 2 different solution!

In application/config/config.php change:

$config['index_page'] = 'index.php';

to:

$config['index_page'] = '';

Step 1 :

Add this in htaccess file

<IfModule mod_rewrite.c>
  RewriteEngine On
  #RewriteBase /

  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteRule ^ index.php [QSA,L]
</IfModule>

Step 2 :

Remove index.php in codeigniter config

$config['base_url'] = ''; 
$config['index_page'] = '';

Step 3 :

Allow overriding htaccess in Apache Configuration (Command)

sudo nano /etc/apache2/apache2.conf

and edit the file & change to

AllowOverride All

for www folder

Step 4 :

Enabled apache mod rewrite (Command)

sudo a2enmod rewrite

Step 5 :

Restart Apache (Command)

sudo /etc/init.d/apache2 restart

-------------------------------------------------------------------------------------------------------

Solution 2:

There are 3 steps to remove index.php

1.Make below changes in application/config.php file

$config['base_url'] = 'http://'.$_SERVER['SERVER_NAME'].'/Your Ci folder_name';
$config['index_page'] = '';
$config['uri_protocol'] = 'AUTO';

2.Make .htacces file in your root directory using below code

RewriteEngine on
RewriteCond $1 !^(index\.php|resources|robots\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L,QSA]

3.Enable rewrite mode (if your rewrite mode is not enabled)

i. First, initiate it with the following command:

a2enmod rewrite

ii. Edit the file /etc/apache2/sites-enabled/000-default
