How can specific lines be queried from one page after including it in another page using PHP?

To query specific lines from one page after including it in another page using PHP, you can read the content of the included page into a variable and then use regular expressions or string manipulation to extract the desired lines. This can be achieved by using functions like file_get_contents() to read the content of the included page and preg_match_all() to extract specific lines based on a pattern. 

<?php
// Include the page
ob_start();
include 'included_page.php';
$included_content = ob_get_clean();

// Define the pattern to match specific lines
$pattern = '/desired_line_pattern/';

// Use preg_match_all to extract specific lines based on the pattern
preg_match_all($pattern, $included_content, $matches);

// Output the matched lines
foreach ($matches[0] as $line) {
    echo $line . "\n";
}
?>
