The second parameter to this function is wrong. It should be '\1' and 
'\3' instead of $1 and $3. $-syntax also exists but it is used in 
different case. If ter rendering contains $ symbols, it may cause 
problems. Correct code will extract \1 and \3 and construct final string 
outside preg_replace.
