PHP 7 vs 5.6 in Ubuntu 14.04

I’m new to php and I’m having problems which I think is related to php versions. I’m getting errors with composer saying

This is what I've done to install php

I have no idea what the problem is as I believe I have the required extensions installed. Any help would be appreciated (assume I know nothing).

Are you trying to install PHP 7? Do you have a /var/www directory where you can create a php file with just


And check if those errors are actually installed?

so I should create a file info.php and place that code into it and then type the ipaddress/info.php into my browser?
I had previous done the above and didn’t get anything to show up I don’t remember the error msg in the browser.

Run it and give us the error message of there is one

File not found. where is the ip of the server and info.php is saved in /var/www directory.

localhost/info.php or

And is your apache service running?

I’m running nginx and it appears to be running.
nginx version: nginx/1.10.1

sudo service nginx restart nginx stop/waiting nginx stop/pre-start, process 2730

localhost/info.php or
nothing happens no error.

Two different ways to do this…

[php]<?php phpinfo(); [/php]

Should produce something similar to the info.PNG image.

Another route would be to run a file thru commandline. Same code in the file, but you would run it as

php /path/to/file/info.php

When I run php info.php I get

Yeah, things aren’t right.

Try installing php7 from here do a git clone to grab it, then run the bash file.

I gete these errors on the last step

sudo ./ mkdir: cannot create directory ‘/usr/local/php7/etc/conf.d’: No such file or directory ln: failed to create symbolic link ‘/usr/local/php7/sbin/php7-fpm’: No such file or directory cp: cannot stat ‘php-src/php.ini-production’: No such file or directory cp: cannot create regular file ‘/usr/local/php7/etc/php-fpm.d/www.conf’: No such file or directory cp: cannot create regular file ‘/usr/local/php7/etc/php-fpm.conf’: No such file or directory cp: cannot create regular file ‘/usr/local/php7/etc/conf.d/modules.ini’: No such file or directory Adding system startup for /etc/init.d/php7-fpm ... /etc/rc0.d/K20php7-fpm -> ../init.d/php7-fpm /etc/rc1.d/K20php7-fpm -> ../init.d/php7-fpm /etc/rc6.d/K20php7-fpm -> ../init.d/php7-fpm /etc/rc2.d/S20php7-fpm -> ../init.d/php7-fpm /etc/rc3.d/S20php7-fpm -> ../init.d/php7-fpm /etc/rc4.d/S20php7-fpm -> ../init.d/php7-fpm /etc/rc5.d/S20php7-fpm -> ../init.d/php7-fpm sed: can't read /usr/local/php7/etc/php-fpm.conf: No such file or directory

It also says that the extension are not compatible with php 7 and I think I need them. Should I use php 5.6 instead?

Okay. I Will look at their install script and what I have on my debian system, and may modify it to work
