Nice to meet you
I would like to combine multiple mp3s in php into one file and play it.
<php
$mp1 = '../mp3/1.mp3';
$mp2 = '../mp3/2.mp3';
$mp9 = '../mp3/9.mp3';
$cmd = "cat$mp1$mp2>";
shell_exec($cmd,$mp9,$rtn);
?>
<audiosrc="<?phpecho$mp9;?>"autoplay="true">
Then only 9.mp3 will be heard, and the connection will not work.
Is the 1.cat connection wrong?
2. Where is the combined mp3 stored?Root, under mp3 folder?
3. Can this combined mp3 file be saved as data?
Thank you for your cooperation.
