PHP: Replace specified tag values in PHP

Question

Take a look at the HTML example below:

<iframe width="AnyNumber" height="AnyNumber">

How can i replace AnyNumber with specified number $1 and $2 for width and height? they can be swapped like:

 <iframe height="AnyNumber" width="AnyNumber">

I'm not sure I understand your question. Are you generating the HTML or are you parsing it and trying to replace some values? (As for attribute order: it doesn't matter.) — Mat, Sep 25 '11 at 11:45
If you want to echo PHP variables in HTML, you do something like — Alex, Sep 25 '11 at 11:48

It reminds me of templates.

For example you have you html files like this

<div class="nav">@navigationMenu</div>
    <img src="@imgSrc">
    <span>@title</title>
    <p>@article</p>

and then with a simple php class you replace with the desired values, for example:

$this->registry->main_layout->set('imgSrc', './img/green.jpg');

There are many tutorials along with the source code (usually a single-simple php class) that implement this.
