Joomla! 4 – The hope of promising year 2018
During 2017, we have heard a lot of opinions that this year has been too gloomy for Joomla. However, we think that this year is so important because it is the stepping stone for the explosion in 2018 when we prepare to welcome Joomla! 4.0 and Joomla! Framework 2.0. In addition to introducing several new features, including a fully rebuilt Media Manager, an enhanced event dispatching system, and new security features such as support for prepared SQL statements, we have also been doing some routine maintenance and paying off some of our project’s technical debt by retiring deprecated code and raising the minimum supported software stack. And, with this released version, we also require PHP 7.
Mac how to Upgrade php v5 to php v7
We will proceed by installing PHP 5.5, PHP 5.6, PHP 7.0, and PHP 7.1 and using a simple script to switch between them as we need.
$ brew install php55 --with-apache $ brew unlink php55 $ brew install php56 --with-apache $ brew unlink php56 $ brew install php70 --with-apache $ brew unlink php70 $ brew install php71 --with-apache
Let's do it!
brew install php71
Or use this code and install php 7.3 without brew
curl -s https://php-osx.liip.ch/install.sh | bash -s 7.3
and after that run this in terminal
export PATH=/usr/local/php5/bin:$PATH
But, we looking Error:
==> Installing php71 from josegonzalez/php Error: Cannot install josegonzalez/php/php71 because conflicting formulae are installed. php55: because different php versions install the same binaries. Please `brew unlink php55` before continuing. Unlinking removes a formula's symlinks from /usr/local. You can link the formula again after the install finishes. You can --force this install, but the build may fail or cause obscure side-effects in the resulting software.
Dont panic! :-) Run unlink command:
brew unlink php55
# Unlinking /usr/local/Cellar/php55/5.5.38_11... 17 symlinks removed
Then try again:
brew install php71 # ==> Summary # ? /usr/local/Cellar/php71/7.1.0_11: 342 files, 39.7M
Then try our php version
php -v

export PATH=/usr/local/php5/bin:$PATH
