A character reference like ₹ is not recognized without the trailing semicolon. Moreover, you can simply use

echo "&#8377;"

or (if you are properly using UTF-8 throughout, which is recommendable) simply

echo "₹";

And quite often you don’t need echo, as you can simply write the reference ₹ or the character ₹ in HTML.

Whether browsers render the “₹” character is a different issue; you should normally do some font settings, possibly with a downloadable font, @font-face.

Figured it:

echo html_entity_decode('₹', ENT_NOQUOTES, 'UTF-8');

echo "&#x20B9;";

Works as long as you are outputting to HTML content, where character references apply. No good for other formats (eg injecting into JavaScript).

echo "₹";

Will work fine as long as your source file is saved in UTF-8 encoding.

Otherwise, the UTF-8 byte encoding of character U+20B9 Indian Rupee Sign is 0xE2, 0x82, 0xB9. So:

echo "\xE2\x82\xB9";

Or, using a function to create UTF-8 strings from code point numbers:

function unichr($i) {
    return iconv('UCS-4LE', 'UTF-8', pack('V', $i));
}

echo unichr(0x20B9);
