arrays - Evaluation Error while using the Hiera hash in puppet -

i have following values in hiera yaml file:

test::config_php::php_modules :   -'soap'   -'mcrypt'   -'pdo'   -'mbstring'   -'php-process'   -'pecl-memcache'   -'devel'   -'php-gd'   -'pear'   -'mysql'   -'xml' 

and following test class:

class test::config_php ( $php_version, $php_modules = hiera_hash('php_modules', {}), $module_name, ){  class { 'php': version => $php_version, }  $php_modules.each |string $php_module| { php::module { $php_module: } } } 

while running puppet manifests following error:

error: evaluation error: error while evaluating function call, create_resources(): second argument must hash   @ /tmp/vagrant-puppet/modules-f38a037289f9864906c44863800dbacf/ssh/manifests/init.pp:46:3 on node testdays-1a.vagrant.loc.vag quite confused on doing wrong. puppet version 3.6.2 , have parser = future 

i appreciate here.

looks yaml off.

1. you don't need quotes in yaml.
2. your indentation 2 instead of one.
3. your first colon on first time spaced. throw syntax error.

it should more this:

test::config_php::php_modules:  - soap  - mcrypt  - pdo  - mbstring  - php-process  - pecl-memcache  - devel  - php-gd  - pear  - mysql  - xml 

in future try , yaml parsers this: link
