In Hebrew leap years, the function will return 6 for Adar A, 7 for Adar B, 8 for Nisan, etc.

In Hebrew non-leap years, the function will return 6 for Adar, 8 for Nisan, etc.

i.e., the "real" Adar is Adar A.

<?php
// Hebrew date in hebrew
$str = jdtojewish(gregoriantojd( date('m'), date('d'), date('Y')), true, CAL_JEWISH_ADD_GERESHAYIM + CAL_JEWISH_ADD_ALAFIM + CAL_JEWISH_ADD_ALAFIM_GERESH); // for today
$str1 = iconv ('WINDOWS-1255', 'UTF-8', $str); // convert to utf-8

echo $str1; // for 23/03/2012 will print: כ"ט אדר ה' אלפים תשע"ב

// or

With PHP 5.5, the functionality changed regarding Adar in a non-leap year. Prior to 5.5, the month was returned as 6. In 5.5 and 5.6, the month is returned as 7. This difference is not listed under "What has changed in PHP 5.5.x".

This function outputs in ISO-8859-8-l.

To convert to unicode UTF-8 do this:

<?php

echo mb_convert_encoding( jdtojewish( unixtojd(), true ), "UTF-8", "ISO-8859-8");

?>

Based on the code already posted by Dave, I've modified it to display the *current* date on a page:

<?php

$gregorianMonth
= date(n);
$gregorianDay = date(j);
$gregorianYear = date(Y);

$jdDate = gregoriantojd($gregorianMonth,$gregorianDay,$gregorianYear);

$hebrewMonthName = jdmonthname($jdDate,4);

$hebrewDate = jdtojewish($jdDate);

list(
$hebrewMonth, $hebrewDay, $hebrewYear) = split('/',$hebrewDate);

echo
"$hebrewDay $hebrewMonthName $hebrewYear";
?>

Sometimes it is useful to have the date in the format YYYY-MM-DD, which is sortable (e.g. you can sort dates by sorting the strings):

<?php
function JDToSortableJewish($jd) {
    return
       
preg_replace("|(\d+)/(\d+)/(\d+)|","$3-$1-$2"// year-month-day
       
preg_replace("|/(\d)/|","/0$1/", // add zeros to the day
       
preg_replace("|^(\d)/|","0$1/"// add zeros to the month
       
JDToJewish($jd))));
}
?>

There's probably a simpler way to do this, but I needed to convert a Gregorian date to a Hebrew one and display it with the Hebrew month name (not the number).

Perhaps it can help somebody...

<?php

//enter your Gregorian date with the variables $gregorianMonth, $gregorianDay, and $gregorianYear using the numerical representation of the month

$jdDate = gregoriantojd ( $gregorianMonth, $gregorianDay, $gregorianYear);

$gregorianMonthName = jdmonthname ( $jdDate, 1 );

$hebrewDate = jdtojewish ($jdDate);

list (
$hebrewMonth, $hebrewDay, $hebrewYear) = split ('/', $hebrewDate);

$hebrewMonthName = jdmonthname ( $jdDate, 4); 

echo
"Your date in Hebrew would read: $hebrewDay $hebrewMonthName $hebrewYear";

?>
