how to get info from TXT file between %%customTags%% as vars??

How do I get text as a variable contents from a TXT file between
certain "custom tags"?

Here is what I mean. If I have a text file named "info.txt" and it's contents are:

Code:

%%meta1%%
This is some dummy stuff for a tag that I might make
%%meta1%%

%%meta2%%
There can be more than one of the current sets
%%meta2%%

%%tag%%
Some of these tags might not even have the same name
%%tag%%

%%changes%%
And I might make a script to add to more tags to this file or 
re-write it occasionally with new tags/contents
%%changes%%

Then in another PHP file I might want to get things like this:

PHP Code:


			
<?

$meta = array("Some of these tags might not even have the 

same name", "There can be more than one of the current sets");

    // or

$meta1 = "This is some dummy stuff for a tag that I might make";

    // or

$tag = "Some of these tags might not even have the same name";

   // etc....

?>

I assume I have to open, then search the TXT file for words that begin after a specified "tag" and end at the same
specified "tag" but I have no idea of the syntax to do that search.

Any help? SHould I be more clear?

Try this (assuming the file with the tags in it is tags.txt):

PHP Code:


			
<?

$lines = file("tags.txt");



foreach ($lines as $line){

 if (preg_match("/%%(\w+)%%/",$line,$match)){

  $last = $match[1];

 }else{

  if ($last){ ${$last} .= $line; }

 }

}



print "Meta1: $meta1<br>\n";

print "Meta2: $meta2<br>\n";

print "Tag: $tag<br>\n";

print "Changes: $changes";

?>

    function cut_html($tag,$string){ 

         

        $tag=str_replace("<","",$tag); 

        $tag=str_replace(">","",$tag); 



        preg_match("!<$tag>(.*?)</$tag>!si",$string,$ok); 





        return ($ok[1]); 

    } 







$str="123 <body>456</body>897"; 



echo cut_html("body",$str); 



?>
