From PHP 5.3 you can use an anonymous function to pass local variables into the callback.
<?php
public function replace_variables( $subject, $otherVars ) {
$linkPatterns = array(
'/(<a .*)href=(")([^"]*)"([^>]*)>/U',
"/(<a .*)href=(')([^']*)'([^>]*)>/U"
);
$callback = function( $matches ) use ( $otherVars ) {
$this->replace_callback($matches, $otherVars);
};
return preg_replace_callback($this->patterns, $callback, $subject);
}
public function replace_callback($matches, $otherVars) {
return $matches[1] . $otherVars['myVar'];
}
?>
