How can the HTML source code help in identifying specific characters in a string in PHP?

To identify specific characters in a string in PHP, you can use the PHP `strpos()` function to find the position of a substring within a string. By using the HTML source code, you can determine the specific characters or patterns that you want to search for in the string. This can be useful when you need to extract or manipulate certain parts of a string based on the HTML structure of the content. 

<?php
$htmlSource = "<p>This is an example string with <strong>bold</strong> text.</p>";
$searchString = "<strong>";
$position = strpos($htmlSource, $searchString);

if ($position !== false) {
    echo "The string '$searchString' was found at position: $position";
} else {
    echo "The string '$searchString' was not found";
}
?>
