If you want to convert a date later than September 22nd 1806, you could use this function. It's a bit crude and due to the fact the original function terminates in the middle of 1806, it uses 1805 as it's 'terminus post quem'.
<?php
function extended_jdtofrench ($juliandate) {
    if (
$juliandate > 2380945) {
       
// jdtofrench () only accepts dates until september 1806
       
$gregorian_date = jdtogregorian ($juliandate);
       
$temp = explode ('/', $gregorian_date);
       
$year = $temp[2];
       
$juliandate = gregoriantojd ($temp[0], $temp[1], 1805);
       
$republican_date = jdtofrench ($juliandate);
       
$republican_date = explode ('/', $republican_date);
       
$diff = $year - 1805;
       
$republican_date[2] = $republican_date[2] + $diff;
    } else {
       
$republican_date = jdtofrench ($juliandate);
    }
    return
$republican_date;
}
?>

Here is a small piece of code to obtain the string data for a correctly converted gregorian date:

<?php
$arDateFrench
= gregorian2FrenchDateArray(11, 9, 1799) ;

echo
$arDateFrench[1] . " " . $arDateFrench[0] . " " . $arDateFrench[2] ;

/* the output will be:
    18 Brumaire VIII

*/

function gregorian2FrenchDateArray($m, $d, $y)
{

   
$julian_date = gregoriantojd($m, $d, $y);
   
$french = jdtofrench($julian_date);
    if(
$french == "0/0/0")
        return
"" ;

   
$arD = split("/", $french) ;
   
   
// get the month name
   
$monthname = FrenchMonthNames($arD[0]) ;
   
   
/* convert the year number to roman digits (as most historians do and documents of the time did */
   
$stryear = decrom($arD[2]) ;
    return array(
$monthname, $arD[1], $stryear ) ;
}

function
FrenchMonthNames($mo)
{
   
/* The names have been invented by Fabre d'Églantine, a second or rather third rank poet
of primarily pastoral poems, with each name referring to the respective period in the agricultural year; e.g. "Vendémiaire" (approx. September) is derived from "vendange" ("harvest"), "Brumaire" (Ocotober/November) from "brume" ("fog") and so on ...     */
   
   
   
$arMo = array("Vendémiaire",

);
      
krsort($digits);
      
$retval="";

Very limited function:

(extract from source of 4.3.3)
These routines only convert dates in years 1 through 14 (Gregorian dates 22 September 1792 through 22 September 1806).  This more than  covers the period when the calendar was in use.

Pour les franais :
Ces routines ne converitssent les dates que de l'an 1 14 (du 22 septembre 1792 au 22 septembre 1806). Cela couvre plus que la priode pendant laquelle le calendrier t utilis.
