My question is related to php include prints 1. In https://github.com/jaimemontoya/jaimemontoya.com/blob/dev/page.php I’m using this:
public function Display()
{
echo "<!DOCTYPE html>nt<head>n";
$this -> DisplayTitle();
$this -> DisplayFavicon();
$this -> DisplayMetaKeywords();
$this -> DisplayMetaDescription();
$this -> DisplayMetaViewport();
$this -> DisplayStyles();
echo "t</head>nt<body>n";
$this -> DisplayHeader();
echo "tt<div class="container">n";
echo $this->content;
echo "tt</div>n";
$this -> DisplayFooter();
echo "t</body>n</html>n";
}
The problem happens in echo $this->content;. In https://github.com/jaimemontoya/jaimemontoya.com/blob/dev/index.php I’m using this:
<?php
require("page.php");
$index = new Page();
$index->content .=
require("scala-programming-projects/scala-programming-projects-book-info.php");
require("success-habits-dummies-zeller/success-habits-dummies-zeller-book-info.php");
.....
.....
.....
$index->Display();
?>
The problem is the ‘1’ that is printed because the include() method, after successfully including the desired file, returns a TRUE value that when echo’ed out is ‘1’.
Do you have specific suggestions to refactor my code to get rid of that ‘1’ or maybe php.ini or some configuration can help in this case? Thank you.

I see that your scala-programming-projects/scala-programming-projects-book-info.php already concat the string. just remove concatenation on index.php
<?php
require("page.php");
$index = new Page();
require("scala-programming-projects/scala-programming-projects-book-info.php");
require("success-habits-dummies-zeller/success-habits-dummies-zeller-book-info.php");
.....
.....
.....
$index->Display();
?>
