Weekday name field descriptor

NiallThistle

I have read online that can use %A to display the full weekday name when formatting a date, however the best I can get is %a to display the abbreviated version, which gives me, for example: Mon, or Tue. %A just displays the letter A.

Can anyone suggest what I might be doing wrong?

According to the manual on date(), to get the full representation of the day of the week you need to use a lowercase l (that is, an L, as in lion).

Drop the percentage symbol as well.

...But [man]date[/man] uses %D for an abbreviated day of the week. %a gives "am" or "pm".

Makes me think this is [man]strftime[/man], which is sensitive to current locale settings, C compiler, and operating system:

As the output is dependent upon the underlying C library, some conversion specifiers are not supported. On Windows, supplying unknown conversion specifiers will result in 5 E_WARNING messages and return FALSE. On other operating systems you may not get any E_WARNING messages and the output may contain the conversion specifiers unconverted.

You can always check what's available on your system

echo 'Uppercase letters'.PHP_EOL;
for ($i = 0x41; $i < 0x5b ; ++$i)
{
	printf('&#37;%%s: %s%s',
		chr($i),
		strftime('%'.chr($i)),
		PHP_EOL
	);
}

echo PHP_EOL.'Lowercase letters'.PHP_EOL;
for ($i = 0x61; $i < 0x7b ; ++$i)
{
	printf('%%%s: %s%s',
		chr($i),
		strftime('%'.chr($i)),
		PHP_EOL
	);
