Also you can use preg_replace with the /e modifier that way you don't have to use eval! Even faster is preg_replace_callback see the earlier posting. Also your regex is faulty '/{(.+?)}/'. The { and } should be escaped since they are metacharacters. so it should read "/\\{(.+?)\\}/". The double \\ will result in a \ in the final regex since PHP uses \ as a metacharacter in strings. Do you really want all characters to appear in the {}? This could lead to unexpected results with your backreference used as a variable. Example: {$myvar} will result in $myvar being matched so what is evaluated later is actually something like "Message $$myvar" which is definetly not what you want. Use something like \w+ to only allow wordcharacters or even better build your own characterclass that actually contains all allowed characters such as [a-zA-Z0-9_-] This will only allow legal characters for php variables.
