In most locale, the first day of the week is Monday. In the US (and presumably elsewhere), the week starts on Sunday.
How can find out in PHP, for an arbitrary locale, the current setting for the first day of the week (Sunday or Monday)?
Here is Solutions:
We have many solutions to this problem, But we recommend you to use the first solution because it is tested & true solution that will 100% work for you.
From CLDR’s supplemental data (release 36, October 2019):
<firstDay day="mon" territories="001 AD AI AL AM AN AR AT AX AZ BA BE BG BM BN BY CH CL CM CR CY CZ DE DK EC EE ES FI FJ FO FR GB GE GF GP GR HR HU IE IS IT KG KZ LB LI LK LT LU LV MC MD ME MK MN MQ MY NL NO NZ PL RE RO RS RU SE SI SK SM TJ TM TR UA UY UZ VA VN XK"/> <firstDay day="fri" territories="MV"/> <firstDay day="sat" territories="AE AF BH DJ DZ EG IQ IR JO KW LY OM QA SD SY"/> <firstDay day="sun" territories="AG AS AU BD BR BS BT BW BZ CA CN CO DM DO ET GT GU HK HN ID IL IN JM JP KE KH KR LA MH MM MO MT MX MZ NI NP PA PE PH PK PR PT PY SA SG SV TH TT TW UM US VE VI WS YE ZA ZW"/> <firstDay day="sun" territories="GB" alt="variant" references="Shorter Oxford Dictionary (5th edition, 2002)"/>
001 is the UN M49 area code for “World”)
Run this command in the shell (bash or sh or etc):
In PHP, call a process to run this command in sh, and get it’s output.
In Python, I does a thing like this:
def getLocaleFirstWeekDay(): return int(os.popen('locale first_weekday').read())-1
Note: Use and implement solution 1 because this method fully tested our system.
Thank you 🙂
