replace tags with PHP variables using preg_match

{$thisname} sho开发者_JS百科uld be converted to <?php echo $thisname; ?>.

{thisname} should be converted to <?php echo $thisname; ?>.

{$this.movie.games} && {$this.new} should be converted respectively to <?php echo $this["movie"]["games"]; ?> and <?php echo $this["new"]; ?>.

$tpl = 'Name: {$name}, Surname: {surname}, City: {$person.address.city}';

function tpl2php($m){
    $var =  $m[1];
    if(strpos($var,'.')){
        $varArr = explode('.',$var);
        $var = $varArr[0];
        for($i=1;$i<count($varArr);$i++){
            $var .= '["' . $varArr[$i] .'"]';
        }
    }
    return '<?php echo $' . $var . '; ?>';
}

$php = preg_replace_callback('/{\$?([_a-z][\w\.]+[\w])}/iS','tpl2php',$tpl);
// Name: <?php echo $name; ?>, Surname: <?php echo $surname; ?>, City: <?php echo $person["address"]["city"]; ?>

Use a templating system, I suggest using http://phpsavant.com/ although it looks like you're more interested in Smarty or Dwoo

There's no need to re-invent the wheel :)

Use the str_replace function.

preg_replace and regular expressions are more flexible than str_replace, especially if you have to parse a string like this.movie to $this["movie"]. It will not be an easy task though.
