Returning Values php - php

All i know from the return statement (based on JS) that is stops execution of the script and return the value and whats after it ignored, then how is that possible
(in fact required) in this php code :
<?php
return "<!DOCTYPE html>
<html>
<head>
<title>$title</title>
<meta http-equiv='Content-Type' content='text/html;charset=utf-8'/>
</head>
<body>
$content
</body>
</html>";
which is completing this :
<?php
error_reporting( E_ALL );
ini_set( "display_errors", 1 );
$title = "Test title";
$content = "<h1>Hello World</h1>";
$page = include_once "templates/page.php";
echo $page;
and also is it possible to have return outside a function ????

You were almost there...
With the template/page.php you don't need to run a return all you need to do is as follows:
<!DOCTYPE html>
<html>
<head>
<title><?php echo $title; ?></title>
<meta http-equiv='Content-Type' content='text/html;charset=utf-8'/>
</head>
<body>
<?php echo $content; ?>
</body>
</html>
Then within the PHP page side of things lets say for example, phpCode.php:
<?php
error_reporting( E_ALL );
ini_set( "display_errors", 1 );
$title = "Test title";
$content = "<h1>Hello World</h1>";
include_once "templates.php";
Include will pull all of the information from the file you're including generally.
You can pull information from anywhere providing you have required the php file. PDO / OOP is a great example of how to do this and I'd highly suggest learning it somewhat more to achieve what you're trying to do (from what I could make out in the question).

Accessing properties in an include when setting that include in to a file

I am trying to create a template html page which I will call via an include to set to a variable, this variable will then be used to set the value of a new file. I need the variables in the included file to be resolved so that the values are populated correctly.
To demo imagine these files:
main.php
$someVar = "someValue";
$fileText = include "aTemplate.php";
$newFileName = 'someFile.php';
if (file_put_contents($newFileName, $fileText) !== false) {
echo "File created (" . basename($newFileName) . ")";
} else {
echo "not created";
}
aTemplate.php
<?php
return
'<!doctype html>
<html lang="en">
<head>
<title><?php echo $someVar; ?></title>
</head>
</html>'
?>
What is currently happening is that the variables stay unresolved and hold no value so in the created html file the title is:
<title></title>
Instead of
<title>someValue</title>
How can I change the 'aTemplate.php' file to resolve the properties set in 'main.php'?
Just use this at your aTemplate.php:
<?php
return '<!doctype html>
<html lang="en">
<head>
<title>'. $someVar .'</title>
</head>
</html>';
?>
There are a couple of problems with your template, firstly as you have the HTML in single quotes, this won't do any of the string substitutions. Secondly, your trying to do a PHP echo whilst in HTML in PHP. I've used Heredoc to enclose the HTML as it allows any sorts of quotes and will also do the replacements.
The substitution of the value is just replaced by adding $someVar directly into the string.
So aTemplate.php becomes...
<?php
return <<< HTML
<!doctype html>
<html lang="en">
<head>
<title>$someVar</title>
</head>
</html>
HTML;
You should echo those string in page instead of return command.
The keyword return is used inside a function while your file is not a function. The browser simply puts what's inside include file has to offer. In you case it is HTML string which should be outputted using echo command.
Also the server executes code in top to bottom and left to right. Thus the variable $someVar will be accessed in aTemplate.php file.
Use below code instead to work
main.php
$someVar = "someValue";
$file = 'aTemplate.php';
// Open the file to get existing content
$fileText = include "aTemplate.php";
$newFileName = 'someFile.php';
// Write the contents back to the new file
if (file_put_contents($newFileName, $fileText) !== false)
{
echo "File created (" . basename($newFileName) . ")"; }
else {
echo "not created";
}
aTemplate.php
<!doctype html> <html lang="en"><head>
<title><?php echo $someVar;?></title>
</head>
</html>

How to properly display an HTML page after PHP script?

somehow I couldn't find an answer to the following problem when searching the web.
I'm not familiar with PHP and am trying to get the below PHP code, which I put right at the beginning of the file, to display the HTML page that follows, instead of "Welcome.".
Many thanks for your time!
<?php
ob_start();
session_start();
if(!isset($_SESSION['userid'])) {
die('<script>window.location = "https://test.com/login.php"</script>');
}
$userid = $_SESSION['userid'];
echo "Welcome.";
?>
<!DOCTYPE html>
<html lang="De">
<head>
<meta charset="UTF-8"/>
...
I found the solution...
<?php
ob_start();
session_start();
if(!isset($_SESSION['userid'])) {
die('<script>window.location = "https://test.com/login.php"</script>');
}
$userid = $_SESSION['userid'];
echo <<<HTML
--> HTML section/code <--
HTML;
?>

How use a php variable declared in the parent file in an included file

I'm trying to pass the php variable $shareURL = "someURL"; from the parent page of test.php into the included file of commentTest.php. Is this possible? If yes, please help.
Parent File = Test.php
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
</head>
<body>
<?php
$shareURL = "someURL";
echo "$shareURL";
include "http://domainName.net/assets/includes/commentTest.php";
?>
</body>
</html>
PHP Included File = commentTest.php
<?PHP
echo "<div class='fb-comments' data-href='$shareURL' data-num-posts='5' data-width='100%'></div>";
?>
HTML Output Source
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
</head>
<body>
someURL<div class='fb-comments' data-href='' data-num-posts='5' data-width='100%'></div></body>
</html>
Change your Test.php to this:
include "/assets/includes/commentTest.php";
Thanks everyone!
Your comments and answers helped me find the solution I needed.
$root = dirname(__FILE__);
include "$root/assets/includes/commentTest.php";
Apparently my root is here /var/www/html instead of right after the TLD in the URL.

In my website I have the same header for all pages. So I use the include function for the header. This includes all the <head></head>.
Because the <title> is variable depending on the page, I have put it just after the <body>.
I know this is wrong. How can I fix this and move the variable <title> inside the standard <head> ?
Thank you
In the code that you include for the header, use a placeholder for the title:
<head>
<title><?php echo $pageTitle; ?></title>
...
</head>
Then, in your page-specific code, just before the include statement, populate the $pageTitle variable:
$pageTitle = "Your Title";
include...
To make your included code more robust, consider setting a default title if none is provided:
<title><?php echo isset($pageTitle)? $pageTitle: 'Default Title'; ?></title>
Set a title variable before including header:
$title = 'Whatever you want';
include('header.php');
//rest of your page
Inside header.php:
<head>
<title><?php echo $title ?></title>
<!-- the rest of your stuff -->
</head>
Put a variable inside of your header file for your title, then define that value in your page before you include the header:
Inside your include:
<html>
<head>
<title><?= $page_title; ?></title>
Inside your main file:
<?php
$page_title = 'My page title';
include('header.php');
Make your included file only contain the contents of the <head> tag, and not the tag itself.
This way you can include the file between <head></head> tags and also have the title differ for each page.
Possibly set the page title in a variable ahead of your include, and have this in the head:
<title><?php echo htmlspecialchars($pageTitle, ENT_QUOTES); ?></title>
You can add a PHP variable above the header include such as
$title = 'test page';
Then in the header you use
<title>Main site title | <?php isset($title) ? $title : 'No title set' ?>
Depending on how you have things set up, you may have to set the title before you call your include.
PHP:
<?php
$title = "My Page Title";
include('path-to-your-header.php);
Your header would look something like this then:
PHP:
<html>
<head>
<title="<?php echo($title); ?>">
...
</head>
Or, if you are using a framework (codeigniter for example) you can use a tempalte - then in your controller method(s) you can set the page title.
PHP:
<?php
// Controller
public function index()
{
$data['page_title'] = 'Your Page Title';
$data['main_content'] = 'home'; // page content
$this->load->view( 'templates/public', $data ); // page template
}
// Tempalte
<html>
<head>
<title><?php echo ($page_title !== '' ) ? $page_title . ' | ' . SITE_NAME : '' . SITE_NAME; ?></title>
...
</head>
<body>
<?php echo $this->load->view( 'header' ); ?>
<?php echo $this->load->view( $main_content ); ?>
<?php echo $this->load->view( 'footer' ); ?>
</body>
in page.php
<?php
$title = 'This title';
include('header.php');
?>
in header.php
<html>
<head>
<title><?php echo isset($title) ? $title : '' ?></title>
</head>

Dynamic Title Tag in PHP

I am trying to dynamically populate the title tag on a website. I have the following code in my index.php page
<?php $title = 'myTitle'; include("header.php"); ?>
And the following on my header page
<title><?php if (isset($title)) {echo $title;}
else {echo "My Website";} ?></title>
But no matter what I do, I cannot get this code to work. Does anyone have any suggestions?
thanks
This works (tested it - create a new folder, put your first line of code in a file called index.php and the second one in header.php, run it, check the title bar).
You should double check if those two files are in the same folder, and that you're including the right header.php from the right index.php. And ensure that $title is not being set back to null somewhere in your code.
Learn more about Variable Scope here.
Edit: Examples of visible changes would be:
TEST1<?php $title = 'myTitle'; include("header.php"); ?>
<title>TEST2<?php if ...
Are you including the header file before or after you set the title variable? If you're including it before, then of course it won't be set.
if you're doing something like this in your index.php:
<?php
include('header.php');
$title = "blah blah blah";
?>
then it won't work - you include the header file and output the title text before the $title variable is ever set.
try to declare the variable before using it
$title = '123';
require 'includes/header.php';
Hi Try this old school method ..
In your Header file (for e.g. header.php)
<?php
error_reporting(E_ALL);
echo '<!DOCTYPE html>
<!--[if IE 7 ]><html class="ie7" lang="en"><![endif]-->
<!--[if IE 8 ]><html class="ie8" lang="en"><![endif]-->
<!--[if IE 9 ]><html class="ie9" lang="en"><![endif]-->
<!--[if (gte IE 10)|!(IE)]><!-->
<html xmlns="http://www.w3.org/1999/xhtml" lang="en-US">
<!--<![endif]-->
<head>';
?>
<?php
if($GLOBALS['title']) {
$title = $GLOBALS['title'];
} else {
$GLOBALS['title'] = "Welcome to My Website";
}
if($GLOBALS['desc']) {
$desc = $GLOBALS['desc'];
} else {
$desc = "This is a default description of my website";
}
if($GLOBALS['keywords']) {
$keywords = $GLOBALS['keywords'];
} else {
$keywords = "my, site, key, words";
}
echo "\r\n";
echo "<title> ". $title ." | MyWebsite.com </title>";
echo "\r\n";
echo "<meta name=\"description\" content='". $GLOBALS['title']."'>";
echo "\r\n";
echo "<meta name=\"keywords\" content='".$GLOBALS['title']."'>";
echo "\r\n";
?>
In you PHP Page file do like this (for example about.php)
<?php
$GLOBALS['title'] = 'About MyWebsite -This is a Full SEO Title';
$GLOBALS['desc'] = 'This is a description';
$GLOBALS['keywords'] ='keyword, keywords, keys';
include("header.php");
?>
I assume your header is stored in a different file (could be outside the root directory) then all the above solutions will not work for you because $title is set before it is defined.
Here is my solution:
in your header.php file you need to set the $title to be global by: global $title; then echo it in your title so:
<?php global $title; ?>
<title><?php echo isset($title) ? $title : "{YOUR SITE NAME}"; ?></title>
Then in every page now you can define your title after you have included your header file so for example in your index.php file:
include_once("header.php");
$title = "Your title for better SEO"
This is tested and it is working.
We can also use functions and its a good way to work on real time web sites.
Do simple:
create an index.php file and paste these lines:
<?php include("title.php");?>
<!doctype html>
<html>
<head>
<title><?php index_Title(); ?></title>
<head>
</html>
-- Then
Create a title.php file and paste these lines:
<?php
function index_Title(){
$title = '.:: itsmeShubham ::.';
if (isset($title)){
echo $title;
}else{
echo "My Website";
};
}
?>
It will work perfectly as you want and we can also update any title by touching only one title.php file.
<?php
echo basename(pathinfo($_SERVER['PHP_SELF'])['basename'],".php");
?>
This works. Since I'm using PHP I don't check for other extensions; use pathinfo['extension'] in case that's required.
You can achieve that by using define(); function.
In your header.php file add following line :
<title><?php echo TITLE; ?></title>
And on that page where you want to set dynamic title, Add following lines:
EX : my page name is user-profile.php where I want to set dynamic title
so I will add those lines that page.
<?php
define('TITLE','User Profile'); //variable which is used in header.php
include('header.php');
include('dbConnection.php');
?>
So my user-profile/.php file will be having title: User Profile
As like this you can add title on any page on your site
Example Template.php
<?php
if (!isset($rel)) {$rel = './';}
if (!isset($header)) {
$header = true;
?><html>
<head>
<title><?php echo $pageTitle; ?></title>
</head>
<body>
<?php } else { ?>
</body>
</html><?php } ?>
Pages Your Content
<?php
$rel = './'; // location of page relative to template.php
$pageTitle = 'This is my page title!';
include $rel . 'template.php';
?>
Page content here
<?php include $rel . 'template.php'; ?>
I'm using your code in my project and it works properly
My code in header:
<title>
<?php
if (isset($title)) {echo $title;}
else {echo "عنوانی پیدا نشد!";}
?>
</title>
and my code in index.php:
<?php
$title = "سرنا صفحه اصلی";
include("./include/header-menu.php");
?>
