IntlChar::charAge
(PHP 7, PHP 8)
IntlChar::charAge — Get the "age" of the code point
Description
public static IntlChar::charAge(int|string
$codepoint): ?arrayGets the "age" of the code point.
The "age" is the Unicode version when the code point was first designated (as a non-character or for Private Use) or assigned a character. This can be useful to avoid emitting code points to receiving processes that do not accept newer characters.
Parameters
-
codepoint -
The int codepoint value (e.g.
0x2603for U+2603 SNOWMAN), or the character encoded as a UTF-8 string (e.g."\u")
Return Values
The Unicode version number, as an array.
For example, version 1.3.31.2 would be represented as [1, 3, 31, 2].
Returns null on failure.
Examples
Example #1 Testing different code points
<?php
var_dump(IntlChar::charage("\u"));
var_dump(IntlChar::charage("\u"));
?>
The above example will output:
array(4) {
[0]=>
int(1)
[1]=>
int(1)
[2]=>
int(0)
[3]=>
int(0)
}
array(4) {
[0]=>
int(7)
[1]=>
int(0)
[2]=>
int(0)
[3]=>
int(0)
}
