I was trying to have to walk the array twice.
The following works:
$pagevars = str_replace($,\\\$,$pagevars);
$page = preg_replace($template,$pagevars,$page);
The reason for using preg_replace is that it does a recursive? replace.
What do you mean, 'recursive' replace?
Example (using shortened arrays):
In my system I build a complete page and then echo it to the browser. All of the
Navigation records and other content pages for the
site are contained in a MySql database.
The only fielsystem files that exist are the main index.php3 script, a site
configuration file that contains defaults for variables
that is imported into a class called site, and the template pages.
The Navigation record for a page determines what needs to happen to it
programmatically (form, database form, text, upload, download
etc...) and whether the page comes from HTTPS or HTTP servers.
//SETUP PAGE STUFF
$template=array(
/({PAGEMAIN})/,
/({PAGELINKS})/,
/({PAGETEXT})/,
/({LINKSDATA})/,
/({PAGEDATA})/
);
$pagevars=array(
PAGEMAIN = get_page($site-page_main),
PAGELINKS = get_page($site-page_links),
PAGETEXT = get_page($site-page_text),
LINKSDATA = ,
PAGEDATA =
);
$page = {PAGEMAIN};
$pagevars = str_replace($,\\\$,$pagevars); // preserve dollar signs in page text
$page = preg_replace($template,$pagevars,$page);
The get_page() fuinction just grabs a text file and stuffs its contents into the
variable.
PAGEMAIN
!-- OUTPUT MAIN BODY TABLE --
table border='0' cellpadding='0' cellspacing='0' width='{WIDTH}' height='77%'
tr valign='top'{PAGELINKS}{PAGETEXT}/tr

!-- OUTPUT PAGE TEXT TABLE --
Because preg_replace walks through the array from top to bottom it becomes sort of
recursive as the resulting string keeps getting
bigger as each variable replacement occurs.
$page
- starts with {PAGEMAIN}
- replaced with PAGEMAIN template which contains {PAGELINKS}{PAGETEXT}
- {PAGELINKS} is replaced with PAGELINKS template which contains {LINKSDATA}
- {PAGETEXT} is replace with PAGETEXT template which contains {PAGEDATA}
- {LINKSDATA} is replaced with programmatically built HTML for links on page
- {PAGEDATA} is replaced with programatically built HTML for the text of the page
(form, document etc..)
The end result is a string of HTML.
I hope this is clear. I may have put you wrong with the use of the word recursive?
I wasn't really sure what term to use. Ever
Expanding?

That's right, you need to escape $ in your replacement strings.

The setup for my templating system:
$template=array(
/({PAGETOP})/,
/({PAGENAVBAR})/,
/({PAGEMAIN})/,
/({PAGELINKS})/,
/({PAGESPACE})/,
/({PAGETEXT})/,
/({PAGENEWS})/,
/({PAGEBOTTOM})/,
/({PAGEDATA})/
);
$pagevars=array(
PAGETOP = get_page($site-page_top),
PAGENAVBAR = get_page($site-page_top),
PAGEMAIN = get_page($site-page_main),
PAGELINKS = get_page($site-page_links),,
PAGESPACE = get_page($site-page_space),
PAGETEXT = get_page($site-page_text),
PAGENEWS = get_page($site-page_news),,
PAGEBOTTOM = get_page($site-page_bottom),
PAGEDATA =
);
$page = {PAGETOP}{PAGENAVBAR}{PAGEMAIN}{PAGEBOTTOM};
$page = preg_replace($template,$pagevars,$page);
echo $page;
Basically each physical page referenced via the get_page function is a text template
that may contain HTML, text or variables in the form {VAR}.
Eventually content from a database ends up in a variable called PAGEDATA which is in
the template stored in the page main variable.
The problem:
PAGEDATA ends up containing page text and it has something like would cost around
$16,000 to complete in that text.
When the preg_replace is performed, something somewhere is assuming that $16 is a
variable (which doesn't exist) and the text ends up as would cost around ,000 to
complete

Is it possible to ask that the this be included as a new feature?
A switch to tell the PCRE engine? to ignore variable substitution?
It would make things a lot easier, I think.

If you don't want to use \n or $n substitution, then maybe you are better off using
str_replace()?
