# Getting error in Yii2.0.16 basic setup

Hi there,
I am getting error while installing new version of yii (2.0.16)
Here is the error:
`Parse error: syntax error, unexpected 'function' (T_FUNCTION), expecting identifier (T_STRING) or \\ (T_NS_SEPARATOR) in F:\wamp\www\\basic\vendor\myclabs\deep-copy\src\DeepCopy\deep_copy.php on line *4*`

Then I have solve this error just by removing this line

`use function function_exists;`

Also @dev_team Please fix this bug and update the repo

Thank You

Its actually not a problem with Yii, nor with the dependency itself (the change was introduced mid 2018). The `use function` syntax is supported since PHP 5.6. Is there any chance that you are using an outdated PHP version?

Can you post the output of `composer diagnose`?
