Custom Tags - preg_replace

[EGONick]

Hello there.

 

I'm in need of some help.  I'm trying to develop a function which searches a page and replaces a custom HTML tag with a content section from the database.  I'm having a problem getting the var name of the content item to fetch it from the database.  When it comes to expressions I'm pants. 

 

Here's my function up to now but, the variable fetched from the tag isn't passed through.

 

function parse_content($content)
{
return preg_replace("/<content var=(.*)>/", get_object("content", '${1}'), $content);
}

 

Anyone got any idea's?  Many thanks.

did you check

OR you can use preg_match first, here you get an array of matches which also contains your match for "()", that you can later use to replace.
