PHP 7 with phpmyadmin gives lots of Deprecation Notices
You can use another PPA for phpmyadmin.Here it is PPA Link
sudo add-apt-repository ppa:nijel/phpmyadmin
sudo apt update
sudo apt install phpmyadmin
As it is only a temporary solution or not a optimal one, till the package of phpmyadmin in ubuntu repos are rebuild.
I had this problem and solved it with a simple reinstall of phpmyadmin and its dependencies. Run the following commands:
sudo apt-get remove --purge phpmyadmin php-gettext php-mbstring -y
sudo apt-get autoremove -y
sudo apt-get update
sudo apt-get install phpmyadmin php-gettext php-mbstring -y
Once reinstalled, you should be good as new!
The way I fixed this problem was by following the askubuntu instructions at depreciation notice error in phpmyadmin with 16.04. It involves changing three lines in /usr/share/php/php-gettext/streams.php and one line in /usr/share/php/php-gettext/gettext.php.
From that link, this are the changes you need to do (if you have ubuntu 16.04):
sudo nano /usr/share/php/php-gettext/streams.php
Line 48 StringReader Error.
Go to Line 52 and change
function StringReader ($str='') {
TO
function __construct($str='') {
Line 84 FileReader Error
Go to Line 90 and change
function FileReader($filename) {
to
function __construct($filename) {
Line 145 CacheFileReader error
Go to Line 146 and change
function CachedFileReader($filename) {
to
function __construct($filename) {
Using sudo nano /usr/share/php/php-gettext/gettext.php.
Line 36 gettext_reader { error
I think you get the gist now, go to line 101 and change
function gettext_reader($Reader, $enable_cache = true) {
To
function __construct($Reader, $enable_cache = true) {
You should try in your php.ini to set error_reporting = ~E_DEPRECATED, this will remove deprecation errors. It should be similiar to error_reporting = ~E_DEPRECATED & E_ALL.
Please let me know if it works.
