PHP Template system - PHP4-5

BillyConnite · Apr 21, 2006

Hey all,

Well I know it took me agggess to find a nice way to create a working template system in php, so loonngg ago I did some searching and editing and the whole works, and here's a simple template system... that works...

CREDIT: Most of code found at codewalkers.com - thanks codewalkers :D

functions.php:

PHP:

<?php

class Page
{
    function Page($template)
    {
        if (file_exists($template))
        {
            $this->page = implode('', file($template));
        }
        else
        {
            die("Template file: $template cannot be found.");
        }
    }

    function parse($file)
    {
        ob_start();
        include($file);
        $buffer = ob_get_contents();
        ob_end_clean();

        return $buffer;
    }

    function replace_tags($tags = array())
    {
        if (sizeof($tags) > 0)
        {
            foreach ($tags AS $tag => $data)
            {
                $data = (file_exists($data)) ? $this->parse($data) : $data;
                $this->page = str_replace('{' . $tag . '}', $data, $this->page);
            }
        }
    }

    function output()
    {
        echo $this->page;
    }
}

?>

index.php:

PHP:

<?php

require_once('template.class.php');

$tpl = new Page('design.html');
$tpl->replace_tags(array(
    'title' => 'This is the title of my html page',
    'content' => 'Here\'s some content which I am putting inside the page, yaaay.'
));
$tpl->output();

?>

design.html

Code:

<html>
<head>
<title>{title}</title>
</head>

<body>

<p>{content}</p>

</body>
</html>

And there you have it, a simple template system, that's quick, and WORKS! :D

Tested on PHP4 and PHP5 servers.

PS - 2ndV added a few (or should I say, took away a few

lines of code also - Thanks).

All the best,
Rhett.

Just a note, really no need to use eregi_replace. str_replace will do the job just fine, and is faster than both ereg(i)_replace and preg_replace

And I'll include a quote from the php manual

If you don't need fancy replacing rules (like regular expressions), you should always use this function instead of ereg_replace() or preg_replace().

Nice none-the-less.

BillyConnite · Apr 21, 2006

Thanks 2ndver :D, I'll change it now, every little bit of optimization counts.

Just did a test on the two, and you're right 2ndver :o

.

This is with preg_replace:

0.000887870788574 seconds
0.000899076461792 seconds
0.000828981399536 seconds

This is with str_replace:

0.000752925872803 seconds
0.000725030899048 seconds
0.000748872756958 seconds

So str_replace is around 0.0009 seconds faster :D - Every little thing counts!

Thanks for the script, I will definately use it. You can almost make an entire CMS system based on that, sweet!

thxs for this, will come in usefull

BillyConnite · Apr 22, 2006

No problem

, hope it helps!

Camron · Apr 22, 2006

Sorry to ask. I am not a php expert. But what exactly would this do? What is the difference from making a phpinclude and just include it in pages?

Thanks,
Camron

It parses the page, rather than including it. It also prevents php scripts from being embedding in the template.

Putting {TITLE} on a page is a lot safter than <?=$pagetitle?>

BillyConnite · Apr 23, 2006

^^ What Jim said

.

It's good too though so that when your selling a php script, and have a template system that parses the pages, the template can be written in 100% html or css so if the buyer has no php knowledge it is much easier and not confusing for them to create a template for the script than when using includes.

All the best, Rhett.

Hey droplister,

No problem, glad it helped :tu:

edmarriner · May 15, 2006

Hi,

This template system is great, but im having trouble using php on the page.
Putting php in the array doesnt work.

e.g.

PHP:

'{CODE}' => 'php code here'

any tips?

thanks,

-ed

BillyConnite · May 15, 2006

Hey ed,

What you could do is parse the php you want in the array first?

So instead of say:
'{CODE}' => '$variable=1+1*10'

You could do:
$variable=1+1*10;
'{CODE}' => $variable

Ofcourse it'd work with any functoins etc you wanted also... BUT I believe there is another way to do it, forgotten how though, I'll see if I can find it for you.

edmarriner · May 16, 2006

hi,

thanks, i never though about doing that, lol i feel stupid now

cheers,

try:

$images = "<img src='images/some.jpg' border='0' alt='' />";
{IMG} => $images

Regards,

BillyConnite · May 25, 2006

Hey crow,

If the page is in a folder, then usually the image path will be wrong as compared with that folder... if you know what I mean.

So you'll have to try the full path i.e. http://domain.com/images/image.jpg instead of just images/image.jpg

Let me know how it goes,
Rhett.

Nice work Billy.

bbalegere · May 26, 2006

Thanks a lot.
I will use it.

Eric · May 26, 2006

I've edited it just a tad, if you don't mind me posting it here Billy

PHP:

<?php

class Page
{
    function Page($template)
    {
        if (file_exists($template))
        {
            $this->page = implode('', file($template));
        }
        else
        {
            die("Template file: $template cannot be found.");
        }
    }

    function parse($file)
    {
        ob_start();
        include($file);
        $buffer = ob_get_contents();
        ob_end_clean();

        return $buffer;
    }

    function replace_tags($tags = array())
    {
        if (sizeof($tags) > 0)
        {
            foreach ($tags AS $tag => $data)
            {
                $data = (file_exists($data)) ? $this->parse($data) : $data;
                $this->page = str_replace('{' . $tag . '}', $data, $this->page);
            }
        }
    }

    function output()
    {
        echo $this->page;
    }
}

?>

Would use it nearly the same way as the original, however, no need to place {} around your tags in the replace_tags array. Also, no need to echo output()

Taken from Billy's original post, replacing w/my changes:

PHP:

<?php

require_once('template.class.php');

$tpl = new Page('design.html');
$tpl->replace_tags(array(
    'title' => 'This is the title of my html page',
    'content' => 'Here\'s some content which I am putting inside the page, yaaay.'
));
$tpl->output();

?>

design.html

Code:

<html>
<head>
<title>{title}</title>
</head>

<body>

<p>{content}</p>

</body>
</html>

wackyjoe · May 28, 2006

umm ok i need to make a news system udner one of my pages and im using this template system...the sites is kinda small since its for a school project

anyway so how would i go about adding the news system in the content area?

would i hve 2 make a completely new file with the news system and do:

$page = new Page("pages/news.php");

BillyConnite · Jun 7, 2006

Hey 2nV, thanks for the update :D - Original post updated with some credit for your help.

wackyjoe, im not quite sure what your getting at. This system would only be used for websites looking to maintin multiple templates, if your only going to use one, then there really is no need at all.

Rhett.

chronic · Jul 14, 2006

Is it possible to output alot of content and some PHP within the array? Would I have to do something like:

PHP:

echo <<<END
This uses the "here document" syntax to output
multiple lines with $variable interpolation. Note
that the here document terminator must appear on a
line with just a semicolon. no extra whitespace!
END;

Hrmm....
not to be any party pooper...
but this code looks remarkably similar to CodeWalkers Template Tutorial located at:
