(PHP 7)
Get the "age" of the code point
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}")
Returns:
The Unicode version number, as an array. For example, version 1.3.31.2 would be represented as [1, 3, 31, 2].
Examples:
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) }
