Answer 1

Yii2 has started using PHP 5.4's Short array syntax. Your error creeps up because of:

spl_autoload_register(['Yii', 'autoload'], true, true);

in Yii.php, which is the new short array syntax. As you have already figured out, you need to install PHP 5.4 now to run Yii2 apps.

---

The commit which made the changes to short array syntax.

The docs and composer details that have been changed.

The discussion where the decision to move to PHP 5.4 was made.

---

As Yii2 is still in heavy development, its requirements are also changing. So be sure to read the readme thoroughly before installing.

See also the Backward Incompatible changes list for PHP 5.4, to make changes to your existing code.

Answer 2

Install PHP 5.4 to resolve this issue.

Yii2 Installation Following command:

(1) First install Composer (LINUX):

Locally:

curl -sS https://getcomposer.org/installer | php

OR

(1) First install Composer (WINDOWS):

C:\Users\username>cd C:\bin

C:\bin>php -r "readfile('https://getcomposer.org/installer');" | php

Note: If the above fails due to readfile, use the http url or enable php_openssl.dll in php.ini

C:\bin>echo @php "%~dp0composer.phar" %>composer.bat*

C:\Users\username>composer -V

Composer version 27d8904

(2) Yii2 framework online downloads:

choose 0 for developemnt and type yes

php yii migrate (/var/www/myyii2$ php yii migrate)

Before this command need to download advance setup like [yii-advanced-app-2.0.7.tgz]
