create a simple script to retrieve vk wall posts using their api

Using vk api, by specifying the domain id , I want to retrieve 100 latest posts and save the audio to the default playlist. Vk api is [login to view URL] . You can use javascript sdk or php or python for this. domain name : *i will specify manually* count : 100 filter : audio fields: audio 1) When I run the php script, it should first clear all tracks in the default playlist 2) Save the list of audio ids into local text file 3) Ignore all duration that has a value of 600 or more 4) Check if audio id already exists in text file. If it exists, ignore
