IntlChar::charAge
Get the "age" of the code point
Description
public static array IntlChar::charAge
( mixed $codepoint
)
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)
}
