如何用PHP替换短语中的单词？

Question

I have couple of mp3 files named 01 - Saanson Ko (Zid) - 128Kbps.mp3 and 01 - Saanson Ko (Zid) - 320Kbps.mp3

I want it to be renamed to 01 - Saanson Ko (Zid) - Muzic.Asia I tried the following code but it did not work. How to do it?

$file = "01 - Saanson Ko (Zid) - 128Kbps.mp3";
$file = "01 - Saanson Ko (Zid) - 320Kbps.mp3";
$mp3_filename = str_replace(".mp3","",$file);
$mp3_filename = str_replace("128Kbps","Muzic.Asia",$file);
$mp3_filename = str_replace("320Kbps","Muzic.Asia",$file);
echo "$file";

Answer 1

str_replace() returns the results.

Try these codes :

$file = "01 - Saanson Ko (Zid) - 128Kbps.mp3";
$file = "01 - Saanson Ko (Zid) - 320Kbps.mp3";
$file = str_replace(".mp3","",$file);
$file = str_replace("128Kbps","Muzic.Asia",$file);
$file = str_replace("320Kbps","Muzic.Asia",$file);
echo "$file";

Answer 2

This should work for you:

You can use preg_replace() and capture the parts which you want and replace it with Muzic.Asia , eg

$file = preg_replace("/ - \d+\w+\.\w+$/", " - Muzic.Asia", $file);
