Installing php7 or newest version on ubuntu 14.0

Question

firstly, i've installed php5 on my system, and i want to upgrade to php7.1 and and then I download the source code from the official website, and I install it.

The installation process was success, when I checked with php -v , it displayed php7.1 But when I check with phpinfo(), it's still displays the oldest php version

how can it happen where there are two different php versions but not stack each other PHP Version 5.5.9-1ubuntu4.22

Now, the problem is how to use the latest php7.1 on my localhost

thanks beforely, i'm sorry if my questions is unexplicit

Answer 1

This is essentially a duplicate of this question which I answered earlier this week. See the accepted solution which will fix your problem.

PHP Parse error: syntax error, unexpected '?' in helpers.php 233

I also recommend just upgrading to Ubuntu 16.04 or 17.10 and using the main supported version instead of a PPA. Just my two cents.

Answer 2

If you didn't install libapache2-mod-php7.1 yet, install it.

then deactivate the older php module:

sudo a2dismod php5 

and activate the new module php7.1 in apache:

sudo a2enmod php7.1

And finally restart apache2:

sudo service apache2 restart
