And, what are you getting now? – Brad
shell_exec("ffmpeg -i $infile -ab 256 $outfile_wav"); shell_exec("ffmpeg -i $infile -ab 256 $outfile_ogg"); shell_exec("ffmpeg -i $infile -ab 256 $outfile_aac"); not conver original file to need formats(( – John Smith
I checked all the directories are correct – John Smith
shell_exec("ffmpeg -i $infile -ab 256 $outfile_aac"); not create good file(bad file with size 0 kb). – John Smith
Make sure your ffmpeg commands work, and then attempt to script it. If you see the ffmpeg console output it will probably tell you why the file is "bad". Also, ffmpeg uses bits as a value for -ab, so you'll want to change -ab 320 to -ab 320k and same for 256. – llogan

first you need use '2>&1' in your code, example

shell_exec("ffmpeg -i $infile $outfile_wav 2>&1");

second, if you have error 'Unsupported codec for output stream' you need install libfaac.dll liblary for ffmpeg in your hosting.
