php - Storing values in two MySQL tables -

-

i have scenario in not sure do.

i have website user can update status. allowing use of hash tags possible user post might like:

went great hike today!! #hiking

now, intend store post in table appropriately named "posts" structured this:

post_id | user_id | text | date

now, when user submits form holds post text run script create array of hash tag terms user used , store them in array. can loop through array , insert tags aptly named "tags" table. structure of table this:

tag_id | post_id | user_id | tag

the problem not know post_id of post until after insert data "posts" table (post_id primary key , auto increment). now, thinking select last row of data "posts" table user (after insert post), , in turn use returned post_id query inserts tag data "tags" table. seems not best way? question is:

is best solution or there better way go scenario?

i brand new stack overflow, don't please down vote me. comment , tell me doing wrong , learn , ask better questions.

thanks

have new column in both tables - unique_id - holds string generate in code before querying database. way have id tie posts , tags before submission. use method time similar applications.

only issue uniqueness, there variety of ways generate unique ids (i use mixture of timestamps , hashing).

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2
