How can conflicts between JavaScript libraries be resolved, specifically in the context of PHP development?

Conflicts between JavaScript libraries can be resolved by using jQuery's noConflict() method to avoid conflicts with other JavaScript libraries that may be using the $ variable. This method allows you to assign a different variable name to jQuery, such as 'jq', and then use 'jq' instead of '$' in your jQuery code.

  <script>
    var jq = jQuery.noConflict();
    jq(document).ready(function(){
      jq("#myButton").click(function(){
        jq("#myDiv").text("Hello World!");
      });
    });
  </script>

  <button id="myButton">Click me</button>
  <div id="myDiv"></div>
