  • Are you incorrectly checking the PHP version of the Server? not your localhost Those modules look like the ones often missing on WAMP.

For upgrading PHP version you can go through following steps Run the following command if you are using linux:

For PHP 5.5, PHP 5.6 and PHP 7.0:

sudo apt-add-repository ppa:ondrej/php

For PHP 5.4 (Deprecated, upgrade at least to PHP 5.5):

sudo apt-add-repository ppa:ondrej/php5-oldstable

For PHP 5.5 (Deprecated, use ppa:ondrej/php):

sudo apt-add-repository ppa:ondrej/php5

For PHP 5.6 (Deprecated, use ppa:ondrej/php):

sudo apt-add-repository ppa:ondrej/php5-5.6

sudo apt-get update

If you are WAMP user then refer following link https://john-dugan.com/upgrade-php-wamp/

Missing extension error

For any missing extension you just need to go php.ini and remove find that extension from the file and remove the semicolon from that line Or if you are on local machine then you can click on wamp,xamp and mamp icon. Go to PHP extensions – > find the missing extension and click on it then restart the server. Following screenshot show how we can do it using wamp.

enter image description here


 sudo apt-get install php7.0-intl
 sudo apt-get install php7.0-xsl

If you have already upgrade then please run following commnad and restart apache:

sudo apt-get update

sudo /etc/init.d/apache2 restart

To switch from 5.5 to 7

 $ sudo a2dismod php5.5 
 $ sudo a2enmod php7.1 
 $ sudo service apache2
