regex help

[drawmack]

I'm having an issue with this regex:

    $template_contents = preg_replace("/\[(\w+)\]/","\${1}",$template_contents);

what I want this to do is the following:

Pass it a string like
Hello [Person] I [Greet] You

and have it spit out
Hello Bob I bid hello to You

where $Person = Bob and $Greet = bid hello to

Right not all that it is doing is stripping the [ and ] from the text.

shouldn't that be \w?

yeah and it is in the code got messed up on the copy and paste.

<?php 

$pattern = array('/\\[\\w+\\]/', '/\\[\\w+\\]/');
$replacements = array('Bob', 'bid hello to');  

$content = 'Hello [person] I [greet] you';

$content = preg_replace($pattern, $replacements, $content, 1);  

echo $content; 
?>

Tom,
that's not what I want. I already have the information in variables and want to perform the replace directly from those variables. I don't want to have to pack an array and then do the replacements.

I fingered it out

preg_replace("/\[(\w+)\]/e","\$\$1",$template_contents);
