IntlChar::charAge
(PHP 7)
IntlChar::charAge — Get the "age" of the code point
Description
public static array IntlChar::charAge ( mixed $codepoint )Gets 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 integer codepoint value (e.g. 0x2603 for U+2603 SNOWMAN), or the character encoded as a UTF-8 string (e.g. "\u{2603}")
Return Values
The Unicode version number, as an array. For example, version 1.3.31.2 would be represented as 1, 3, 31, 2.
Examples
Example #1 Testing different code points
<?php
var_dump(IntlChar::charage("\u{2603}"));
var_dump(IntlChar::charage("\u{1F576}"));
?>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)
