Embedding PHP variables in HTML code

Question

This was probably asked earlier, but I could not find the answer to my question with some preliminary searches, so here it is:

A very simple example of my current method of entering PHP variables into HTML is as follows:

HTML (file.php):

<tag><?php echo $variable; ?></tag>

PHP:

$variable = "value";

ob_start();
include "file.php";
$results = ob_get_clean();

This allows me to get the correct result, but it annoys me every time I have to copy and paste these three lines to get the variables embedded in my HTML files. I probably want to change the details of this injection function to a later date, and it is currently scattered in several hundred places throughout my code.

, "". , . , :

function injectVariables($filePath, array $variables)
{
    //Built-in PHP function, extracts array key => value pairs into variable $key = value pairs in the current scope
    extract($variables);

    ob_start();
    include $filePath;
    return ob_get_clean();
}
