PHP date and time conversion into Chinese day of the week

PHP Input date and time. To automatically convert it to a day of the week, you can use strtotime() date(). To change it to a Chinese day of the week, you need another array mapping~

PHP Convert date and time to Chinese day of the week

After PHP 5.4, the array writing method can be simplified using [], and it can be used directly after being declared, so I wrote two simple versions for reference~

<?php
function  get_chinese_weekday ($datetime)
{
    $weekday =  date ( &#39;w&#39; , strtotime ($datetime));
    return  &#39;星期&#39; . [ &#39;日&#39; , &#39;一&#39; , &#39;二&#39; , &#39;三&#39; , &#39;四&#39; , &#39;五&#39; , &#39;六&#39; ] [ $weekday ] ;
}
?>

PHP >= 5.4 You can use the above version.

<?php
function  get_chinese_weekday ($datetime)
{
    $weekday   =  date ( &#39;w&#39; , strtotime ($datetime));
    $weeklist =  array ( &#39;日&#39; , &#39;一&#39; , &#39;二&#39; , &#39;三&#39; , &#39;四&#39; , &#39;五&#39; , &#39;六&#39; );
    return  &#39;星期&#39; . $weeklist [ $weekday ] ;
}
?>

PHP < 5.4 Use the above version.

Debain / Ubuntu If you have the php5-intl package installed, you can Use IntlDateFormatter to write (PHP 5 >= 5.3.0, PECL intl >= 1.0.0)

<?php
$fmt =  datefmt_create (
    &#39;zh_TW&#39; ,
    IntlDateFormatter :: FULL ,
    IntlDateFormatter :: FULL ,
    &#39;Asia/Taipei&#39; ,
    IntlDateFormatter :: GREGORIAN ,
    "EEEE"
);
echo  datefmt_format ($fmt, strtotime ( &#39;2014-05-04 15:10:11&#39; )); //星期日
$fmt =  datefmt_create (
    &#39;zh_TW&#39; ,
    IntlDateFormatter :: FULL ,
    IntlDateFormatter :: FULL ,
    &#39;Asia/Taipei&#39; ,
    IntlDateFormatter :: GREGORIAN ,
    "EEEEE"
);
echo  &#39;星期&#39; . datefmt_format ($fmt, strtotime ( &#39;2014-05-04 11:10:11&#39; )); //日
?>

Usage example

echo get_chinese_weekday('2014-05-26 00:11:12');
