    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");

    ?>

    If you wish to format the hebrew date as this (ignore the brackets): [כ"ז סיון ה'תשע"ה], since none of the 3 bitmasks include this format, you can use the CAL_JEWISH_ADD_GERESHAYIM mask, and then insert the ' into the year with the second line, as shown:

    $hebdate = jdtojewish(gregoriantojd(6,14,2015),1,CAL_JEWISH_ADD_GERESHAYIM);
    $hebdate = substr_replace($hebdate,"'",strrpos($hebdate," ")+2,0);

    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";
    ?>

    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.

    Check whether the year is leap year, in order to determine whether the value 7 = Adar or Adar 2

    <?php

    $hebrewDate     = jdtojewish(gregoriantojd(date('m', $DateStamp), date('d', $DateStamp), date('Y', $DateStamp)));
    list(    $hebrewMonth, $hebrewDay, $hebrewYear) = explode('/',$hebrewDate);

    $m = array(3, 6, 8, 11, 14, 17, 19);
    $meuberet = in_array(($hebrewYear % 19), $m);
    if(    $meuberet) if($hebrewMonth == 7) $hebrewMonth = '7b'; //This is Adar 2

    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";

    ?>

    To check if a Jewish year is leap use this function:

    function isJewishLeapYear($year) {
        return 0 != cal_days_in_month(CAL_JEWISH, 6, $year);
    }

    In non-leap years there is only one Adar, and its number is 7. There is no 6.

    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))));
    }
    ?>
