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?
