Hi Lenylance.
IF she has a non-Filipino passport only....
shouldn't be any problems, but you will need to accompany her and enter the country(Phils) with her.
Make sure you have her birth certificate with you, and yours (plus any other Filipino IDs you may have).
Ask for a Balikbayan stamp for her passport when you reach immigration at the airport in Manila.
She's then good to stay for one year.
The next step is to get her 'recognised' as a Filipino citizen...because she is the daughter of a Filipino.
There is a govt. procedure and a fee for this, after which she will receive a certificate with her photo on it, confirming her status.
She can then live in the Phils as long as she likes without the need for a Balikbayan or any type of visa.
I did this for my UK-born son. He lived there for periods of up to 3 years, as well as attending school there.
