preg_replace

xwin

I'm having a problem with preg_replace... it's placing all the replacements at the top of the string and not where they should be... where the replacements should be it's putting 1's instead.

$search = '/\<global_template=\"(.*?)\"\>/e' ;
$replace = 'include("./global_template/$1.tpl")';
$file = preg_replace($search, $replace, $file) ;
echo $file ;

the global template files each just contain one word, header, navigation, and footer, so it's getting them correctly (see below).

here's the code of $file, which is loaded through file_get_contents:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
       "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">

  <head>

<title>{$CONFIG['site_name']}</title>

  </head>

  <body>

<global_template="header">

<global_template="navigation">

<% SOURCE %>

<global_template="footer">

  </body>

</html>

here's what it's outputting right now:

Content-type: text/html

X-Powered-By: PHP/4.3.10

Set-Cookie: ZDEDebuggerPresent=php,phtml,php3; path=/



headernavigationfooter<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
       "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">

  <head>

<title>{$CONFIG['site_name']}</title>

  </head>

  <body>

<% SOURCE %>

  </body>

</html>

as you can see, the problem is not that it's getting the right templates, it's just not putting them in the right place.

It should be putting them where the 1's are.

I was also wondering how to make it insert a newline above the replacement... I tried \n but it doesn't seem to work too well with preg_replace.

Thanks! 🙂

Well, that's not the code you're actually using, because there are several parse errors in it. At least have the requisite quotes in the include statement:

$replace = 'include("./global_template/$1.tpl")';

xwin

argh... i was trying to oversimplify it too much...

should be ok now.

basically, it works when $1 is replaced by itself but there seems to be issues when it is included... it doesn't seem to include itself in the right place.

Ah, I see now.

Rereading the manual definition for [man]include[/man] it returns true on success and false on failure. It's the return value that's used for the replacement text. (true, in this case, which is cast to a string as "1").

Maybe include() isn't what you're after. Maybe file_get_contents() will do better. Something like this wee thing might work as a starting point.

xwin

yes, thanks, file_get_contents works well.

my only problem is that file_get_contents won't parse php variables stored in the file it's accessing and displays the text of the variable rather then the variables contents. Is there a way to get around this?

Use preg_match to search for variables, then eval() them.

xwin

I could use eval, but my code requires minimum overload and eval slows down the code way too much.

Another preg_replace_callback() could do the job, perhaps.

{$CONFIG['site_name']}

could be matched by

/\{\$(.*?)\}/

(Yes, all those characters have special meanings in regexps.) The callback function will need to be able to find the data that is supposed to be inserted, of course.
