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

You can insert script to HTML like in any other  non-PHP  page  PHP processes it like any other code    lt button id  butt  gt      Click ME     lt  button gt    lt script gt      document getElementById  butt   onclick   function              alert  Message           lt  script gt      You can use onSOMETHING attributes    lt button onclick  alert  Message    gt Button lt  button gt      To generate message in PHP  use json encode function  it can convert to JavaScript everything that can be expressed in JSON     arrays  objects  strings          lt  php  message    Your message variable     gt    lt button onclick  alert  lt   htmlspecialchars json encode  message   ENT QUOTES   gt    gt Click me  lt  button gt      If you generate code for  lt script gt  tags  do NOT use htmlspecialchars or similar function    lt  php  var    Test string     gt    lt button id  butt  gt Button lt  button gt    lt script gt      document getElementById  butt   onclick   function              alert  lt   json encode  var   gt           lt  script gt      You can generate whole JavaScript files  not only JavaScript embedded into HTML  You still have to name them with  php extension  like script php   Just send the correct header   script php     The JavaScript file   lt  php header  Content-Type  application javascript       This meant the file can be used in script tag      gt    lt  php  var    Message     gt   document getElementById  butt   onclick   function          alert  lt   json encode  var   gt        index html     Example page that uses script php   lt  doctype html gt   lt html lang en gt       lt head gt           lt meta charset  utf-8  gt           lt title gt Page title lt  title gt       lt  head gt       lt body gt           lt button id  butt  gt              BUTTON          lt  button gt            lt script src  script js  gt  lt  script gt       lt  body gt   lt  html gt

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
