Answer 1

Put the render code in a my_navbar.php
echo '<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
<ul class="nav navbar-nav">
<li>
<a onclick="load_home()"href="#">About</a>
</li>
<li>
Services
</li>
<li>
Contact
</li>
</ul>
</div>';
and then in all php file you need the navbar put
<?php
include_once "my_navbar.php"; // this will include a.php
?>
Use include_once for avoiding multiple include

Answer 2

To expand on scaisEdge's comment, here's how you can do this in an include.
In nav.php (name it however you want):
<?php
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
<ul class="nav navbar-nav">
<li>
<a onclick="load_home()"href="#">About</a>
</li>
<li>
Services
</li>
<li>
Contact
</li>
</ul>
</div>
?>
Then where you want the navigation:
<?php include('nav.php'); ?>

Answer 3

You can use include(), i.e.:
navigation.php
<?php
echo <<< EOF
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
<ul class="nav navbar-nav">
<li>
<a onclick="load_home()"href="#">About</a>
</li>
<li>
Services
</li>
<li>
Contact
</li>
</ul>
</div>
EOF;
anotherfile.php
<?php
include("navigation.php");
//the rest of the code...
include vs include_once:
The include_once and require_once functions are slower than include
and require, simply because they keep track of the files that have
already been included, to avoid including them more than once.
