Checking if a file is MP3

[LanceT]

I know with images you can use

 

images/jpg

 

but how do you check it with an MP3?

 

sounds/mp3 ?

 

lol.

 

Thanks in advance.

checking the extensions would be the basic to it, however, i believe there are some more complicated way to ensure that the uploader listens to mp3, this is the extension checking.

<?php
$ext = explode(".", $filename)
if ($ext[1] == "mp3") {echo "It is a mp3 file";}
else {echo "It isnt a mp3 file";}
?>

@ted- the problem with your script is that files named this way for an example won't work: file.name.mp3 or file.MP3

 

Solution:

<?php

$ext = strtolower(substr(strrchr($filename,"."),1));
if ($ext == "mp3")
echo "Mp3";

?>

you can also use substr

$filename = 'somefile.mp3';

// check if file has an .mp3 file extension
if(substr($filename, -4, 4) == '.mp3')
{
   echo 'Mp3s are not allowed!';
}
else
{
    echo 'File is ok!';
}

 

Umm Orio beat me to it

Btw, I checked what mime type does php give for mp3 and it's audio/mpeg.
