I just learned how to include php .Here's the index or main php file
<!DOCTYPE HTML>
<html>
<head>
</head>
<body>
<?php include 'header.php'; ?>
</body>
</html>
now in header.php file which way is better to print html
Way 1 directly use html without php
<header>
<h1>Header</h1>
</header>
Way 2 Using php and echo
<?php
echo '
<header>
<h1>Header</h1>
</header>
'
?>
Another quick question. Will it work if I use .html for the base or index file ??
sorry for my bad english
Directly use HTML without PHP:
<header>
<h1>Header</h1>
</header>
As for your second question:
The file you're using include() in must have .php extension, but the file that's being included doesn't necessarily need the .php extension. The .html extension would work fine as well.
Just include the PHP file.
BTW, in case you haven't, read about this too:
Difference between require, include and require_once?
HTH.
you should use include_once ;-)
http://us2.php.net/manual/en/function.include-once.php
There are a few ways to go around it. Rather than echoing everything, I like to go like this:
<title><?php echo $title; ?></title>
Or if I have a nice block to work with, maybe within an if statement, I also like to go like this :
<?php if($weather = "sunny") { ?>
<div id="sunny">
<p>It's a beautiful day outside.</p>
</div>
<?php } // end if($weather = "sunny")
else { ?>
<div id="sunny">
<p>Today is yucky.</p>
</div>
<?php } ?>
The answer is sometimes different. If you use the same header on a lot of pages, use Way1. If you're only doing this in one place, you want to use Way 2 (or keep it in html), since it's more readable at quick glance to someone studying the page.
You can use .html for the file if you change the server config to tell it to look at it for php first, but you shouldn't do that, it just increases complexity and may have unintended consequences if you do it wrong.
Use .php or .phtml for files with any amount php in it. The only distinction you can make is to use .phtml files for files that are mostly html.

As the title says, is there a way to edit a portion of an entire site with one code or page? For example, if the bottom of every page of a site said "2014", is there a way in html or css to change every page of the site to say "2015" without having to do so manually to each individual page?
I understand this can be done in php, and I understand that a server can be configured for html to read php code. Are there any flaws to this method (perhaps the html page will load slower if it's configured to read php)? Are there any other ways to do this besides using php code?
Performance Concern:
You will not see any performance difference between having PHP render basic HTML and typing the HTML yourself.
The performance impact is only noticeable on HUGE PHP applications. And even then, it's still very fast.
What you ask is common practice. This is an example of what you can do.
Make a file called index.php and put this inside:
<!doctype html>
<html>
<head>
<!--Your head stuff-->
</head>
<body>
<header><?php require_once 'header.html' ?></header>
<section class="main_content"><h2>My Page!</h2></section>
<footer><?php require_once 'footer.html' ?></footer>
</body>
</html>
Make a file called header.html and put this inside:
<h2>This is my header</h2>
Make a file called footer.html and put this inside:
<h2>This is my footer</h2>
As you can see, the practice is to use any of the built-in PHP functions to include other files in your PHP file:
include 'some_file.php';
require 'some_file.php';
require_once 'some_file.php';
I think Dreamweaver can do this, with its find and replace entire website property
Assuming all pages have a CSS file in common, you can use the content CSS property of a pseudo element like before or after to control content across all pages.
For example:
#footer:before {content:'2015';}
<div id="footer"></div>
I see multiple answers about creating php files in order to reuse headers/footers, but nothing specific enough. I can't seem to get it to work.
What exactly would the php file look like and what exactly would my html file look like (given the code as it currently is, below)? do I have to convert all my html files to php files in order to use the php include line?
<div id="footer2-wrap">
<div class="container">
<table id="header">
<tr>
<td class="phone-number"><span class='wsite-text wsite-phone'>Copyright 2015 | xxx Corporation</span></td>
</tr>
</table>
</div>
Create a new file with your footer data. Let's give it the name: footer.php:
<div id="footer2-wrap">
<div class="container">copyright etc...</div>
<div>
Then inside your master template (or index.php file), include the footer file:
include_once('footer.php');
You should work with include(), require() or require_once functions in PHP to include your files, which depends on your situation.
For instance, let's assume you have a basic php file, called index.php and you want to add sidebar.php, footer.php, navigation.php.
index.php
<!DOCTYPE html>
<html>
<head>
<title></title>
<meta charset="utf-8">
<link rel="stylesheet" href="style.css"/>
</head>
<body>
<?php
include("sidebar.php");
include("navigation.php");
include("footer.php"); // we include footer.php here. you can use .html extension, too.
?>
</body>
</html>
footer.php (or html)

Yes, you must have a .php file to use PHP, your server must also have PHP installed (but most already do). PHP also adds to the loading time of a page, so take that into consideration when using it. To add the footer with PHP, you can use the PHP function include(), or, I am not sure if this is considered correct, with file-get-contents():
include():
<?php
include("footer.html");
?>
file-get-contents():
<?php
$footer = file_get_contents('footer.html');
echo $footer;
?>
You could also do the same thing with JavaScript:
var xmlhttp, text;
xmlhttp = new XMLHttpRequest();
xmlhttp.open('GET', 'http://www.example.com/file.txt', false);
xmlhttp.send();
text = xmlhttp.responseText;
document.getElementById("footer").innerHTML=text;
Code taken from here.
Note: The file must be on the same domain to use JS.
First create a file called menu.php(if you use .html it wont work)
On that php file write the html code for your menu
<div id="navbar">
more code
</div>
At your main html file write
<?php
include("menu.php");
?>
The code should be able to run. Make sure you are running the code via Apache. Download Xammp or wammp. Start Apache, copy paste your project folder to the xammp folder under httdocs. Then on your browser type in localhost/[your project name] and make sure the html files are changed to .php.
Where is the right place to include a file when working with HTML and php?
Before the HTML code:
<?php include 'file.php' ?>
<html>
<head>
</head>
<body>
</body>
</html>
In the head tag:
<html>
<head>
<?php include 'file.php' ?>
</head>
<body>
</body>
</html>
In the body tag:
<html>
<head>
</head>
<body>
<?php include 'file.php' ?>
</body>
</html>
Include the file wherever it would otherwise be in the code...
Example:
- If the include is an html form, it would go in the body.
- If the include is a php script to process the form, it would probably go in the head.
If your imported file is just code with no characters outside the PHP blocks then it doesn't matter. I'd personally put it in the top of the file, so that I could use ini_set affecting the whole execution or send headers or cookies.
I you have content to be printed in the file's main code or outside PHP blocks you should put the file where you want the content.
Just noting, if you want keep the main HTML structure static in your main file and still want to print to both <body> and <head> I suggest you do both in functions, add the import to the file top and call the functions to print.
PHP doesn't care where you put it. For purposes of displaying your page, though, it depends on what is is the included file. For example, if file.php contains the body of your table, obviously it should go in the <body> tag.
It depends on your need.
If your file.php file has some global functions that you'd like to access throughout your code, then I would say include it at the top. Additionally, if you're doing anything with the headers in the included file, definitely include it at the top.
However, say your file.php contains a dynamic javascript code (in other words a script that is changed by php depending on the situation), then the header is probably the best location for it, since that is more or less the standard location to place javascript.
Finally, if your file.php is meant to bring in actual html or structure to the file, then definitely include it in the body.
I have some html files that are exactly the same, except for a little area where goes some text. And I was thinking if there was a way to save writing the same text in the 7 files.
I thought on a possible soluction, but I find it a bit messy:
I split the page in 2 parts, upper.php and lower.php:
upper.php
<html>
<head>
...
</head>
<body>
...
<div id=content>
lower.php
</div>
...
</body>
</html>
And then I write the different pages like this:
home.php
<? include "upper.php" ?>
Welcome to my webpage where I do random stuff.
<? include "lower.php" ?>
contact.php
<? include "upper.php" ?>
Contact me by sending an email to asdf#a.org
<? include "lower.php" ?>
etc..
I suspect that this is a very dirty way to do it, any other workaround?
That's how I do all my websites. Sometimes there'll be settings before the first include (such as to determine if the user must be logged in or not), but for the most part that's how I like to do things.
The only real issue is to make sure that you don't get mixed up if you have files in different folders. Other than that, you should be good.
I've been working on a small page in PHP, one that doesn't need the power of a full-fledged framework behind it. One thing that I'm really missing from previous work in Ruby-on-Rails is the ability to effectively pass content up the page using "content_for".
What I was wondering is, how could you create a page lifecycle that would accomplish this same effect in PHP?
So, here's a simple example:
Let's say you have a template that defines an index page, just a recurring header and menu you want to use on all your pages. So your index.php file looks basically like this:
...header stuff...
<body>
<?php include $file.'.php'; ?>
</body>
...footer stuff...
EDIT: Thanks for the tips on URL security, but let's just assume I'm getting the user request safely :)
Now, lets say in the header you want to put this:
<head>
<title><?php echo $page_title; ?></title>
</head>
It would be nice to be able to specify the title in the included file, so at the url http://example.com/index.php?p=test you're loading test.php, and that file looks like this:
<?php $page_title = 'Test Page'; ?>
... rest of content ...
Now, obviously this doesn't work, because the including page (index.php) is loaded before the variable is set.
In Rails this is where you could pass stuff 'up the page' using the content_for function.
My question is this: What would be the simplest, leanest way that you all can think of to effect this kind of 'content_for' functionality in PHP?
Ideally I'd like suggestions that don't involve strapping on some big framework, but some relatively light boilerplate code that could be used in a lot of different applications.
Never do include $_GET['p']. This opens a huge security hole in your site, as include accepts filenames and URLs, so anybody would be able to read any file on your site and also execute any code on your server. You may want to check and sanitize the value first.
If you need something simple, you may put header and footer in separate files, execute your test.php which would set the variables, capture its output using output buffering, then include the header, output the middle part and include the footer. Example:
<?php ob_start(); ?>
<body>
<?php include $filename.'.php'; ?>
</body>
<?php $content = ob_get_clean();
include 'header.php';
echo $content;
include 'footer.php';
?>
If I understand you correctly (I have not used RoR extensively), you could put your data in a variable or a function. If your content was in a variable, your "test.php" could simply hold all your variables and you could load it at the very beginning of your index file (likewise for a function depending on how complicated your needs are; if you're doing a lot of extra work, you may need to use a function as a variable won't work).
For example, your test.php would look something like this:
<?php
$page_title = "Test Page";
$page_content = "Some sort of content";
// Or
function page_content()
{
// Run some functions and print content at the end
}
?>
Then, in your index.php
<?php include $_GET['p'].'.php'; ?>
...header stuff...
<title><?php print $page_title; ?></title>
<body>
<?php print $page_content; ?>
<!-- OR if function -->
<?php page_content(); ?>
</body>
...footer stuff...
This way everything should load properly. You could also split things up, but that would complicate your structure (especially if there is no need for an elaborate framework, this would be unnecessary).
Good luck!

Are you worried about XSS? Or are you going to filter/whitelist the "filenames" from the query string?
My answer would be to use mod_rewrite -- if you're using PHP, you're likely using Apache!
You could filter out files with a RewriteCond and your RewriteRule could be:
RewriteRule /index.php?p=(.*)$ $1 [L,QSA]
This may be a different approach than the PHP functionality you were looking for, but it comes to mind...
