Sintaxys of Rules validation, elements separated by comma or not?

Yii 1.1

Hi , what is the correct sintaxys for write validation rules ?

by example . . .

array(‘first_name, date_update, date_birthdate ,compliance’,‘length’, ‘max’=>1)

OR

array(‘first_name’, ‘date_update’, ‘date_birthdate’ ,‘compliance’,‘length’, ‘max’=>1)

Both sintaxys are valid ?

or for second sintaxys we need a special configuration of PHP version ?

my php configuration:
PHP Version 5.6.40-0+deb8u12
Linux debiandb 4.9.0-18-amd64 #1 SMP Debian 4.9.303-1
Apache 2.0

Yii Version 1.1.13

Note: with the second sintaxys the app show errors, when we change to the first sintaxys all work good !

Described here
https://www.yiiframework.com/doc/guide/1.1/en/form.model#declaring-validation-rules

Each rule returned by rules() must be of the following format:
array(‘AttributeList’, ‘Validator’, ‘on’=>‘ScenarioList’, …additional options)
where AttributeList is a string of comma-separated attribute names which need to be validated according to the rule;

It should be:

[['first_name', 'date_update', 'date_birthdate' ,'compliance'], 'length', 'max' => 1]

Not that list of attributes is wrapped in array.

Can or should? (I do not remember)

In Yii 1.1 you can pass attributes either as array or string (multiple attributes separated by comma). In Yii 2 you should use array (although you can pass string, but it will work only for single attribute, you can’t pass multiple attributes in that way).

Yes, I just looked it up:

if(is_string($attributes))
$attributes=preg_split(’/\s*,\s*/’,trim($attributes, " \t\n\r\0\x0B,"),-1,PREG_SPLIT_NO_EMPTY);
