How to inject javascript code dynamically before body tag using php?
<p>Ｉam using a custom mvc framework that i built myself. I would like to ask how can we dynamically include javascript files to the bottom of my page?</p>

<p>Create Account Page (createaccount.php)</p>

<pre><code>&lt;?php include('header.php'); ?&gt;

&lt;div class="container maincontainer"&gt;
&lt;h3&gt;Create an Account &lt;/h3&gt;

&lt;?php include('footer.php'); ?&gt;
</code></pre>

<p>My  tag is in the footer.php.</p>

<p>I have another page called </p>

<p>Login Page (login.php)</p>

<pre><code>&lt;?php include('header.php'); ?&gt;

&lt;div class="container maincontainer"&gt;
&lt;h3&gt;Login &lt;/h3&gt;

&lt;?php include('footer.php'); ?&gt;
</code></pre>

<p>Basically, this 2 pages use different javascript files. I want to include different js for different page. Note：they are using same footer.php file</p>

<p>Is there any function/method that i can write to inject js code dynamically to the footer.php based on specific pages? Advice from experts appreciated greatly!</p>

<p>Cheers</p>
