RE: [PHP] Re: template in message string

an example line would be nice ?? and basically my string will be returned like $string = "Something $var1 something else $var2"; from $string = "Something {var1} something else {var2}"; that preg statement i posted seemed to work for me ?? so therefore $var1 = "test"; $var2 = "test2"; echo $string; would hopefully return Something test something else test2 how can i do this without eval it didnt seem to working within a function :\ -----Original Message----- From: SLanger@spirit21.de [mailto:SLanger@spirit21.de] Sent: Thursday, April 17, 2003 5:15 PM To: daniel@electroteque.org Cc: php-general@lists.php.net Subject: Re: [PHP] Re: template in message string Hello Look at the posting to "preg_replace brain teaser" for a faster way of doing it. Also you can use preg_replace with the /e modifier that way you don't have to use eval! Even faster is preg_replace_callback see the earlier posting. Also your regex is faulty '/{(.+?)}/'. The { and } should be escaped since they are metacharacters. so it should read "/\\{(.+?)\\}/". The double \\ will result in a \ in the final regex since PHP uses \ as a metacharacter in strings. Do you really want all characters to appear in the {}? This could lead to unexpected results with your backreference used as a variable. Example: {$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.
