Execute the Code in a PHP Page And Echo the HTML Output - php

I absolutely don't post a question here in SO unless I really can't find a way to solve my problem myself. I did a lot of googling and was not able to find a solution for this one problem I am about to describe.
Here is the problem. I am creating a templated php website. With templated I mean something like below:
<?php include("header.php");?>
<div id="content">
<div id="main">
<h2><?php echo($page_title);?></h2>
<?php
echo ($page_content);
?>
</div>
<?php include("sidebar.php");?>
</div>
<?php include("footer.php");?>
As you can see here page template ECHOES the content of the $page_content variable between header and footer sections to build the page.
To keep the code clean and separated (in my own way) I have been placing the html content in .txt files (let's say page1_content.txt) and assigning the txt content to this variable ($page_content) as below:
$page_content = file_get_contents("page1_content.txt");
My problem starts when I place some php code in page1_content.txt, lets' call this file page2_content.php (yes, I change the file from .txt to .php). Then I assign the content of this file to $page_content variable as below as usual:
$page_content = file_get_contents("page2_content.php");
Now, when the page template ECHOES page2_content.php contents the php code in it is also echoed as string and not executed, but I am trying to query a database and do some stuff in this file with some php code. I mean, I want the php code inside page2_content.php to be executed and the cumulative html code to be echoed by the "echo" line inside the template file.
How can I achieve this?
Please ask me any questions if you need more info/clarification.
Thanks
EDİT:
As many people here suggested the solution was including the file. Actually, I tried including the file before but it didn't look like it was working, it broke my template, so I though I was on the wrong track and quit the "include" way of doing this. Since everybody here is advising to use include I tried that again. I replaced the php code in "page2_content.php" with a basic 1-line code just to see if it gets executed before adding generated html code without breaking the template and it worked. Apparently my php code had a problem at first place and hence broke my template execution.
Now I have changed the template structure slightly and pages using the template, and it seems to work nicely. Thanks a lot everybody. I have up-voted every answer suggesting that I use include :)

As #Ali suggested, you could include the files. The other option which I highly suggest you do not use is the eval() function.

I think what you want to do is to include your content PHP file, not echo it (as you are doing with header.php and footer.php).
echo($page_content);
Would become as below:
include("page2_content.php");

You've already done this in your footer and sidebar, just use include()

Google analytics dynamic php, where to include code?

The question has been asked before but none of the previous answers that I have found solves my problem.
This is the structure for my web page.
index.php calls the loader.
loader.tpl generates <head>, generates <body> by include header.tpl, include $body and include footer.
A separate php page holds the functions and a new page is generated by calling a function that sets $page to a new value matching a .tpl file.
I've created the analyticstracking.php file and placed it in a folder.
I've tried placing<?php include_once("foldername/analyticstracking.php") ?> pretty much in every place I can think of. Either it doesn't do anything at all or it causes an error.
No error code is given, it only returns a blank grey page.
I tried copying the script code straight into the body of the $page template and it only generated an error.
I'm out of ideas.
Where should I place
Since I've tried any number of different locations, it would be great if you could give an answer so foolproof that it can't be miss interpreted.
Thanks

include() doesn't work when my page has GET param

I have a header.php file containing my DOCTYPE and all my links/scripts.
I use
<?php
// HTML DOCTYPE insert
include 'header.php';
?>
at top of all my pages to have only one header for everyone, and it works fine.
Now, I have another page that get from a database a summary of my products information. When someone click on the "read more" link:
<p>
read more...
</p>
another page opens with the full information displayed...
Actually that works...
BUT on my new page (display_product.php/id=[anynumber]) my included file doesn't work. So I have no nav bar, no scripts, no stylesheet. Only the text from my database.
AND the weird thing is that when I copy/paste the HTML of my generated display_product page and launch it on my browser, it works... O-o
So the generated code is good.
AND the second weird thing is that when I get rid of the /?id... my layout works fine (but I have no text anymore, of course)
Does one of you have an idea why this crazy things happens?
"Hi guys, Thanks very much Fred -ii this was it. it works perfectly. Thanks sergiodebcn for your concerne."
Since other answers were given and did not solve the actual problem, am posting my comment to an answer, in order to close the question.
Remove the slash from /?id
The slash is trying to instruct the server to probably find a folder after a filename, which technically looks like is what's happening here.
The ultimate solution for include and require functions with path issues, is to use the absolute filesystem path to the file that you want to include or require.
i.e you may say:
include("C:\\www\\app\\incs\\header.php");
Hint
To learn how to set the absolute path for include dynamically for your project, check the source code of two files of cakephp framework:
index.php
webroot/index.php

PHP includes header or footer location

I was hoping someone could help. I have just started to dabble with PHP includes for time saving in the future. For example I want to change the footer and header on a web page once (using include) instead of copying and pasting the code 30 or 40 times - oh no... a typo start again.
Which brings me to the question(s) where is it best to place this script?
<?php include("includes/headernav.html"); ?>
Can it be placed in a div, or should it be placed at the top of your code under the body?
If I want to make an image/banner include module. Can I
<?php include("includes/image.jpg"); ?>
Or is best to wrap the image in html and apply like this?
<?php include("includes/imagewrapped.html"); ?>
Do not include .jpeg files directly, use a wrapper. Only use include with other PHP files.
As for including the header, do it any way that feels natural as long as it produces valid html. There is no particular reason to declare another div element.
Hope this helps:
<?php include("includes/ui_header.php"); ?>
My page content between header and footer
<?php include("includes/ui_footer.php"); ?>
You can probably save this as a function and call that function wherever you want to display.
It doesn't matter whether you put include in any place. However, it's better to put include in the top or bottom of your code
While including headers/footers/menus on the site, please keep in mind following things:
1) Your header/footer includes(blocks) should be wrapped inside a div.
2) This way then can be differentiated and any new change to them can be done easily.
3) Its always a good practice to include a wrapper div around an element as CSS can use it for styling.
4) Your header/footer includes (blocks) should have a flexibility that even we place them in header,footer or any sidebar, they should not disturb the UI.
1) Because you are including the HTML file, you probably need to include it where you want to display it.
2) Create a function in php where you send only image URL (maybe some other parameters) and function returns the HTML code (String) which you only echo on page where you want to display it. This way you can ensure, that all images will have the same code and styling.
for example
function generateImage($url=null) {
if (isset($url)) return '<img src='.$url.' style="width: 100px; height:100px; border: 1px;" />';
else return false;
}
The better way is to include always a php file.

OpenCart PHP Custom Function Not Working

I'm having a bit of difficulty including a custom php function in an opencart template. Here's what's going on.
In the header.tpl file, I'm inserting this code in the portion:
<?php
$blah = file_get_contents("my_url_goes_here");
?>
<?php
echo $blah;
?>
Then in the footer.tpl file, I'm inserting this code:
<?php if(!isset($blah)) die; ?>
The purpose of this is to detect whether my blah function in the header is still there, and if it's not there to exit the script.
However, it seems the die function is throwing me for a loop, because if I move it up to the header.tpl file, so all the code is together, it works perfectly as designed.
But if I move it to the footer.tpl file, where I want it to go, it kills the script no matter what, and I end up with a blank page - even if the blah variable is intact in the header.tpl file.
This has got me pretty confused, and I can't figure out why it's not reading my variable if it's in a different file, as both of those files should be included on every page.
Thanks in advance for any thoughts!
They are two separate entities, and as such data from one will not be in the other. I'm guessing this is some kind of detection script for reversed code like many do for wordpress templates. OpenCart is MVC based not linear and as such, $blah in the header is disregarded almost as soon as the code in it is completely executed

Include a repetitive chunk of HTML

I basically have a div on my site that always has the same stuff. However, this div is not present on all pages which is why I won't use the dynamic web template. I was wondering if it was possible for PHP to get the code from a document on the server and put in into the div?
Ex:
<div id="section...
then my text file contains
<p>hello</p>
Basically I want PHP to put it into the div when the user sees it.
If theres a smarter way of acheiving this I'd be open to it as well.
Thanks
Simply include() the file. The interpreter will drop out of PHP mode back into HTML mode, outputting anything it encounters.
Did you try this in the first place?
<div id="section"><?php include ('path-to-your-file') ?></div>
Just have a file with some echo statements that generate your div and then include it only when required.
How to control whether to include it or not depends on how your website is built.
For instance if you have DB entries for your pages add a column called includediv (you can probably come out with a better name...) and if that is true you include the file otherwise not.
