Question

I would like to convert this text {unsubscribe|here.} to <a href="">here.</a>.

I have already wrote the regular expression that picks up the different groups of matches.

In this case I know I can preg/str_replace the front and the end (}) of the text however this would be ineffective as i also would like to strip out another value like this which would be {name} for example.

This is the regular expression I have wrote. /(\{unsubscribe\|)([a-z]*[^\}])(\})/

Thanks,

$str = '{unsubscribe|{name} here.}';

function fix($m){
    return "<a href=''>".str_replace("{name}", "MY NAME", $m[1])."</a>";
}
print preg_replace_callback("/\{unsubscribe\|(.*)\}/", "fix", $str);

output:

<a href=''>MY NAME here.</a>
