PHP Installation and Configuration

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

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

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

And check if those errors are actually installed?

#3

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.

#4

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

#5

File not found.
http://192.168.1.20/info.php where 192.168.1.20 is the ip of the server and info.php is saved in /var/www directory.

#6

localhost/info.php or 127.0.0.1/info.php

And is your apache service running?

#7

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

#8

localhost/info.php or 127.0.0.1/info.php
nothing happens no error.

#9

Two different ways to do this…

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

info.PNG

When I run php info.php I get

Yeah, things aren’t right.

Try installing php7 from here https://github.com/kasparsd/php-7-debian do a git clone to grab it, then run the bash file.

#12

I gete these errors on the last step

sudo ./install.sh 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?

#13

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