How to add schema markup on dynamic codeigniter pages - codeigniter

Question

I want to add schema markup on dynamically created codeigniter pages. as per my understanding you can add schema to optimize SEO search results and it can be added in header file. But i have dynamically created pages which shows different category pages and i need to add scheme for all those category pages.
Problem is how to add different schema for multiple pages if there is only one header for all pages.
Here is the view page code:
<?php
$this->load->view("landing/header");
?>
<div class="container" >
<?php
for ($i = 0; $i < count($services); $i = $i + 3) {
?>
<div class="row <?= (($i != 0) && ($i != (count($services) - 1))) ? 'sm-pad-v' : '' ?>">
<?php
for ($j = 0; $j < 3; $j++) {
if (isset($services[$i + $j])) {
?>
<div class="col-md-4 assignment-content">
<h3>
<strong>
<?= $services[$i + $j]->service_name; ?>
</strong>
</h3>
<p>
<?= trimText(strip_tags($services[$i + $j]->description), 150) ?>
<a class="" href="<?= base_url($services[$i + $j]->seo_url) ?>"><span class="read-more">read more</span></a>
</p>
</div>
<?php
}
}
?>
</div>
<?php
}
?>
</div>
Here is the code for schema markup:
<script type="application/ld+json">
{
"#context" : "http://schema.org",
"#type" : "Organization",
"name" : "Programming Assignment Help",
"alternateName" : "AJAX Programing Assignment Help",
"url" : "https://www.assignment.com/"
}
<script type="application/ld+json">

"#type" : "Organization ",

"contactType" : "customer service"
}]
}
<script type="application/ld+json">
