i am doing something like this
$some_var='<!DOCTYPE html>
<head>
<title>questions '.$suto.'</title>
<meta charset="utf-8" />
<meta name="description" content="question need to'. $suto.'">
'. include ("header.php") .'
<body>
There is more code below which is working that's why not posting here.
Everything works instead the include function.
Instead of include() you can use file_get_contents() like,
$some_var='<!DOCTYPE html>
<head>
<title>questions '.$suto.'</title>
<meta charset="utf-8" />
<meta name="description" content="question need to'.$suto.'">'.file_get_contents("header.php").'
<body>
file_get_contents() is a PHP function which is one of the preferred way to read the contents of a file into a string.
include() will parse PHP code inside the included file. And file_get_contents() will return the content of the file. Here, you are storing the content to a string. So the file_get_contents is the right option.
You could use file-get-contents function (http://php.net/manual/en/function.file-get-contents.php)
$some_var='<!DOCTYPE html>
<head>
<title>questions '.$suto.'</title>
<meta charset="utf-8" />
<meta name="description" content="question need to'. $suto.'">
'. file-get-contents ("header.php") .'
<body>';
