How can PHP developers ensure cross-browser compatibility when playing music on a website?

To ensure cross-browser compatibility when playing music on a website, PHP developers can use HTML5 audio tags with multiple source elements to provide fallback options for different browsers. By including different audio formats (e.g., mp3, ogg, wav) within the source elements, developers can ensure that the audio will play on a wide range of browsers. 

<audio controls>
  <source src="audiofile.mp3" type="audio/mpeg">
  <source src="audiofile.ogg" type="audio/ogg">
  <source src="audiofile.wav" type="audio/wav">
  Your browser does not support the audio element.
</audio>
