IntlChar::isspace — Check if code point is a space character
$codepoint
)Determines if the specified character is a space character or not.
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 TRUE
if
codepoint
is a space character, FALSE
if not.
Example #1 Testing different code points
<?php
var_dump ( IntlChar :: isspace ( "A" ));
var_dump ( IntlChar :: isspace ( " " ));
var_dump ( IntlChar :: isspace ( "\n" ));
var_dump ( IntlChar :: isspace ( "\t" ));
var_dump ( IntlChar :: isspace ( "\u{00A0}" ));
?>
以上例程会输出:
bool(false) bool(true) bool(true) bool(true) bool(true)
