What best practices should be followed when using jQuery in PHP to avoid potential bugs or errors?

When using jQuery in PHP, it is important to ensure that the jQuery library is properly included in your HTML file before any jQuery code is executed. This can help avoid potential bugs or errors related to jQuery not being loaded correctly. Additionally, using the `$(document).ready()` function can ensure that your jQuery code is executed only after the DOM has fully loaded, preventing any issues with elements not being available when your code runs.
