Simple question on arrays and sql

Given that I have a 2D array in php, is there a sql syntax to insert the
entire array at once?

For example if I retrieve a set of data from one table in the database
with keys A, B and C, and suppose there are 100 records, and I build an
array $arr consisting of

$arr[$i]['A'], $arr[$i]['B'], and $arr[$i]['C']

where $i goes from 0 to 99,

is there a syntax to insert the entire $arr array at one time into
fields A, B, and C of a new table?

I really would like to avoid having 100 sql insert calls.
BTW, this is for an Oracle DB.

In the past I have only had to insert a few records at a time, so i
simply did multiple inserts. Of course for Oracle I could do the same
and only do a commit after all are done.

Why not use an INSERT ... SELECT syntax and do it all in SQL?

Sometimes the most obvious solution is the last one you see. This will
do it:

INSERT INTO AA (A, B, C) SELECT A, B, C FROM BB WHERE blahblahblah

Thank you
