simple replacment with regex - problem - Joomla! Forum - community, help and support

hi!
i tried write simple replacement plugin j1.5, replace text between {mytext} {/mytext} html, error:

parse error: syntax error, unexpected t_variable, expecting '{' in /home/techniczne/www/html/kreatywwwny/plugins/content/reqreplace.php on line 14

my plugin code:

code: select all

<?php

defined( '_jexec' ) or die( 'restricted access' );

$_mambots->registerfunction( 'onpreparecontent', 'plugreplacer' );

   function plugreplacer( $published, $row, $params, $page=0  )
        $regex = "{mytext}(.*?){/mytext}";
      $row->text = preg_replace_callback( $regex, 'run_replacer', $row->text );
       return true;
}

function run_replacer( &$matches ) {
        $text = $matches[1];
        $text = "<b>$text</b>";
        return $text;
}
?>

where problem? ideas?

thanks!

the left curly bracket missing function definition:

code: select all

 function plugreplacer( $published, $row, $params, $page=0  ) {
