  • 0

I’d like to be able to replace things in a file with a regular expression using the following scheme:

I have an array:

$data = array(   'title' => 'My Cool Title',   'content' => '' )

I also have a template (for clarity’s sake, we’ll assume the below is assigned to a variable $template)

<html> <title><% title %></title> <body><% content %></body> </html>

I’d like to be able to use one regular expression to do the whole thing, so it can be as general as possible; The following is my stab at it (which doesn’t work)

$endMarkup = preg_replace('/<% ([a-z]+) %>/',$data['\\1'], $template);

Is there a clean solution for putting associative array data into a template by array index?

  1. With a little work before hand you can do it with a single preg_replace call:

    $replacements = array(); foreach ($data as $search => $replacement) {    $replacements['/<% $search %>/'] = $replacement; } $endMarkup = preg_replace(      array_keys($replacements),       array_values($replacements),       $template);
