Let’s look at important things here –
Sun - Sun represents Personality, King, Government, Father, Authority, Career, Top Positions, Ego, Self Esteem, Health, Education etc.
Purva Phalguni - Purva Phalguni is nakshatra of Luxury, Wealth and Lavish Life. It is also nakshatra of creative pursuits and love/romance. For detailed information, please check this - https://www.astrosaxena.com/ppnaksh.
Leo - As Purva Phalguni is a part of Leo, Leo sign and its representations become important. Leo is 5th sign of zodiac belt, hence it represents the things associated with 5th house of horoscope like Love, Creativity, Arts, Being on Stage etc. Besides that, Leo is basically the Lion. This is the sign of feeling like King or Queen. Also, it is a sign of independence, Confidence, Ego, Self Esteem etc. Leo is consisted of 2 and half Nakshatra namely Magha, Purva-Phalguni and Uttara-Phalguni. Leo's lord is Sun..
Sun - As Sun rules Leo, Sun's position and dignity is important to know about the overall functioning of any planet in Purva Phalguni/Leo.
Venus - As Purva Phalguni is ruled by Venus, Venus's position and dignity will also have an important role in functioning and results of any planet in Purva Phalguni.
Houses Involved – Also, we can’t afford to forget the houses involved as a planet can be ruling different houses and sitting in different house for every person as per ascendant and planet’s position. To know overall affect, we have to consider the houses involved as those areas of life are being impacted.
Interpretation of Sun in Purva Phalguni Nakshatra – As Sun represents career, authority and recognition, these people get these things through creative pursuits. They can be seen as celebrities who find their recognition through their arts or skills. They can also be working in financial fields as this is nakshatra of wealth, luxuries and ruled by Venus. As Sex is important part of mythological story of this nakshatra, they can be working in sex industry or any work related with sex. Their ego feels satisfied if they have wealth, luxuries and conveniences of life. They would love to get a celebrity status. As discussed, it can be a good position for someone in Sex related career but when it comes to dealing with relationship matters in their personal life then Sun takes the shape of Ego and their relationship matters can suffer due to ego issues. So, this position can be excellent for getting authority from creative interests/pursuits or in financial field of work like stocks/shares but it can be troublesome for relationship matters as they can be hurt by ego conflicts.
Role of Sun – As we are interpreting Sun only, we need not to separately see Sun's position as Leo's lord.
Role of Venus - Likewise, Venus placement is important to guide Sun in right direction, being Purva Phalguni's lord.
Other Factors – And of course, we need to consider conjunction, aspects, house lordship, house position and dashas etc to know the exact results of Sun in Purva Phalguni. So, we always need to take a holistic view of chart rather than just 1 planetary position.
Conclusion – So, this is how I see Sun in Purva Phalguni can work in a chart.
