Parameters:

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:
Returns TRUE if codepoint is a "graphic" character, FALSE if not.
Examples:
Testing different code points
<?php
var_dump(IntlChar::isgraph("A"));
var_dump(IntlChar::isgraph("1"));
var_dump(IntlChar::isgraph("\u{2603}"));
var_dump(IntlChar::isgraph("\n"));
?>
