PHP版本必须等于或高于5.6

I have updated PHP 5.5.9 to PHP 5.6.31 using the command lines in Ubuntu. This is the picture

And then I was trying to install CakePHP, but it is showing that "your PHP version must be equal or higher than 5.6.0 to use CakePHP."

This is the error message of cakePHP

I am doing work in Linux(Ubuntu) Operating system.

What can I do now?

Your PHP CLI version and the version configured with your web server can very well be different. If you check phpinfo(), you can see exactly what paths and what not are in use.

I have found the solution. PHP CLI and PHP Apache are the different module. We have to notice the Apache server PHP version which is showing by-

<?php
phpinfo()
?>

To run the same version, first I disabled the PHP 5.5.9 version-

sudo a2dismod php5

Then I enabled the PHP 5.6 version-

sudo a2enmod php5.6

Restart the server-

sudo service apache2 restart
