Re: regular expression in replace()

You need \\ not \, and you need \. in the second argument (otherwise
you'll replace evey letter by \.)


so to search for all occurrences of the fixed string $aaa in a string
$string and replace them by $bbb you need something like

replace($string,
  replace($aaa,'[.+\[\]\\?$^]','\\$0')
  $bbb)

You may need to include other suntax characters in the inner call to
replace so they all get quoted with \ before $aaa is used in the main
call to replace().
