One way to avoid accidentally including the same script twice is to implement a script management module in your templating system  The typical way to include a script is to use the SCRIPT tag in your HTML page      lt script type  text javascript  src  menu 1 0 17 js  gt  lt  script gt    An alternative in PHP would be to create a function called insertScript      lt  php insertScript  menu js     gt

To avoid escaping lot of characters      echo  lt  lt  lt MYSCRIPT          script here         MYSCRIPT    or just turn off php parsing for a while     gt     your script here  lt  php

You mean JavaScript   Just output it like anything else in the page    lt script type  text javascript  gt     lt  php echo  alert  message        gt   lt  script gt    If want PHP to generate a custom message for the alert dialog  then basically you want to write your JavaScript as usual in the HTML  but insert PHP echo statements in the middle of your JavaScript where you want the messages  like    lt script type  text javascript  gt    alert   lt  php echo  custom message    gt      lt  script gt    Or you could even do something like this    lt script type  text javascript  gt    var alertMsg     lt  php echo  custom message    gt      alert alertMsg    lt  script gt    Basically  think about where in your JavaScript you want PHP to generate dynamic output and just put an echo statement there
