Complete tutorial on converting PHP AMR to MP3

In this article, we will provide a complete tutorial to demonstrate how to convert AMR format audio files to MP3 format using PHP. In this tutorial, we will use the FFmpeg tool to implement this conversion process and will provide you with detailed steps and code examples.

Step One: Preparation

Before you start, you need to make sure you have installed the FFmpeg tool. You can check whether FFmpeg has been installed by running the following command:

ffmpeg -version

If you have not installed FFmpeg, you can follow the guidance of the official documentation to install it.

Step 2: Write PHP code

Next, we will write PHP code to call the FFmpeg tool to convert AMR to MP3. The following is the sample code:

<?php
$amrFile = "input.amr";
$mp3File = "output.mp3";

$cmd = "ffmpeg -i $amrFile -acodec libmp3lame $mp3File";

exec($cmd);

In the above code, we first define the input AMR file name and the output MP3 file name, and then use the exec() function to execute the FFmpeg command. Please make sure you have the appropriate permissions to execute system commands.

Step Three: Test the Code

Now you can create a PHP file and copy the above code into the file. Replace the $amrFile and $mp3File variables with your own file paths. Then, test the code by accessing this PHP file:

php convert.php
