Phrasal verb

I`m an English teacher. I need some help with a phrasal verb: let through, what does it mean? Thank you for your help.

It could be let through as in:

A: We need to get in, we simply can't miss the concert. Please!
B: Okay, I am going to let you through, but if anybody asks — you sneaked in!

This is not a phrasal verb.

[philo2009]

It means 'allow to pass through (a gate or other barrier)'.

I agree with the previous answer: it is not a true phrasal verb, but a loose combination of transitive verb and (depending on the presence or absence of a nominal object) a preposition or adverb.
