I have a entity string such as /ədɪʃ<sup>ə</sup>n/ in my database.
I want to convert this entity to its vowel word like this '/ədɪʃ<sup>ə</sup>n/'. I want this convert in php for checking. 
Can anyone suggest a solution for this ?
I want to convert this entity #601; ipa number to its corresponding vowel letter.
