how to join mp3 in linux machine using php

I have this mp3 folder that contains mp3 generate from Google Text To Speech (TTS).

I using WinSCP to access the webserver which is using Linux.

Since the number of mp3 in this folder is not fix, i cant use this command to join the mp3 via php script.

cat file开发者_Python百科1.mp3 file2.mp3 > new_file1.mp3

This command works but it join the mp3 without the correct order.

cat *.mp3 > new_filename.mp3

Question is how to join the mp3 based on the date time it created? Or if i rename all the mp3 into 1.mp3 etc filename, i want it to be join based on the filename ascending.

ls -t | xargs cat > new_filename.mp3

Are you using FFMPEG or php (I'm not familar with php)?

http://ffmpeg.mplayerhq.hu/download.html

FFMPEG will do the job, here is the command to concatenate files:

cat output1.mpg output2.mpg output3.mpg > outputall.mpg

You have sth.mp3 sth.mp3 sth.mp3 ... ok?

(time based: )

ls -lt | grep -i mp3 | awk '{ print $8}' | xargs > x cat

(time based (Reversed )

ls -ltr | grep -i mp3 | awk '{ print $8}' | xargs > x cat
