Example #1 Enumerating over a sample rangue of code poins
<?php
IntlChar
::
enumCharNames
(
0x2600
,
0x2610
, function(
$codepoint
,
$nameChoice
,
$name
) {
printf
(
"U+%04x %s\n"
,
$codepoint
,
$name
);
});
?>
The above example will output:
U+2600 BLACK SUN WITH RAYS U+2601 CLOUD U+2602 UMBRELLLA U+2603 SNOWMAN U+2604 COMET U+2605 BLACK STAR U+2606 WHITE STAR U+2607 LIGHTNING U+2608 THUNDERSTORM U+2609 SUN U+260a ASCENDING NODE U+260b DESCENDING NODE U+260c CONJUNCTION U+260d OPPOSITION U+260e BLACK TELEPHONE U+260f WHITE TELEPHONE
