make array of string to boolean

Question

How can I make this into a boolean?

I tried this :

array('FALSE' => 'No', 'TRUE' => 'Yes')

I want the TRUE/FALSE to be treated as a boolean and not a string. How to do this?

When you put values in quotes, they are treated as strings. Simply use the true and false boolean keywords, eg

array(
    false => 'No',
    true  => 'Yes'
)

Be mindful that PHP will auto-cast true to 1 and false to 0 in this case because

The (array) key can either be an integer or a string

This won't stop you being able to use $array[true] or $array[false] though.

Shouldn't it be otherwise? true and false cannot be array indexes. I think Yes and No are supposed to be those.

@Hanky웃Panky Depends what the OP wants to do. This array could be used as part of a translation / i8n file for yes/no value output
