$content = include('file2include.php');

Well I tried something funny some days ago - include a file with include and put it in a variable :-)

file2include.php

PHP Code:


		
			
<table>

<tr><td><?php echo 'hello world' ?></td></tr>

</table>

now I include that file like:

PHP Code:


		
			
<?php

$content = include('file2include.php');



echo $content;

?>

Now what I get in the Browser is:

HTML Code:

<table>

<tr><td>Hello World</td></tr>

</table>1

Now I wondered where that 1 comes from? Is it a true which comes since the file was successfully included - and get's converted to a 1?

(This thread is not about - if we should use something like that above or not ;-) )

include comes back as a boolean

If the file has been included successfully, and there is no return statement in the included file, $content will be an integer 1. If the file returned something, then $content will be that value. If the file could not be included for whatever reason, then $content would be a boolean FALSE and an E_WARNING would be issued.

lol, sorry for an dumb question like that, but I got a code like that

PHP Code:


		
			
$content = include('pages/ok_cart_product.php');

$content  = substr($content,0,-1);

echo $content;

So I thought the one was added at the end of $content -since he cutted the last character away :-D

changed it now to

PHP Code:


		
			
include('pages/ok_cart_product.php');

since there is no need of $content ;-) | THX for clearing that up

In a more learning purpose.. How would you get the content of a PHP file(with the PHP intact), and assign in to a variable? Is that even possible?

Same way you would any text file, fopen.

It is possible with file_get_contents and eval if you wish to execute the code, too. If nobody else has posted the code for you by the time I get my laptop back, I will write an example :-) !

No idea how wildhoney wants to go with eval - but you can do it like:

PHP Code:


		
			
<?php

ob_start();

include('file2include.php');

$var = ob_get_contents();

ob_end_clean();

?>



<html>

<head></head>

<body><?=$var ?></body>

</html>

and the file which gets included:

PHP Code:


		
			
<table>

  <tr>

    <th>Column 1 Heading</th>

    <th>Column 2 Heading</th>

  </tr>

  <tr>

    <td><?='content1' ?></td>

    <td><?='content2' ?></td>

  </tr>

</table>

Would give that output:

HTML Code:

<html>

<head></head>

<body><table>

  <tr>

    <th>Column 1 Heading</th>

    <th>Column 2 Heading</th>

  </tr>

  <tr>

    <td>content1</td>



    <td>content2</td>

  </tr>

</table>

</body>

</html>

:-)

Edit: sorry forgot to explain what happens actually:

PHP Code:


		
			
<?php

ob_start(); //This is starting the buffer

include('file2include.php');//now we load the file into the buffer

$var = ob_get_contents();// load the buffer to $var

ob_end_clean();//delete the buffer

//and thats it ;-)

?>

@Saka why would you do all that?
I usually just say include (...)

Well as I said it was not my code -and I changed it later on to just "include" - but you could use for something like:

We want to build an small login widget. The html code is somewhere in an extra html file, and we are currently in a class which builds the sidebar widgets.

Now we dont want to "echo" the code when it is executed since we still have some other html which goes first (<head></head><body> etc.). So we could go, copy the content in our variable - and include it anywhere in our site.

Well, it might not be the best example - but I cannot think of any better atm :-D

That lost me...
If you had a function that spit out a your login/join box, you would say:

PHP Code:


		
			
<?php

 display_login();

?>

// display_login would be a div with a form. Right?

Personally I would have a file called loginbox.php with my form code, then if I needed that my code would be:

PHP Code:


		
			
<h1>Welcome please log in:</h1>

<?php include_once('loginbox.php'); ?>

If I did the function, I'd just have it <<<EOF out, then do my code...
