PHP RegExp Help

How code php regexp to replace simultenously symbol ( to { and ) to }.

 

No need for regex,

$str = str_replace(array('(', ')'), array('{', '}'), $str);

PHP:

str_replace() is much faster than preg_replace() (Unless you need to use regular expression for a reason we're not aware of)

 

Thanks for you help. You're great.
