IntlChar::isUWhiteSpace — Check if code point has the White_Space Unicode property
$codepoint
)Check if a code point has the White_Space Unicode property.
This is the same as IntlChar::hasBinaryProperty($codepoint, IntlChar::PROPERTY_WHITE_SPACE)
Note:
This is different from both IntlChar::isspace() and IntlChar::isWhitespace() .
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
has the White_Space Unicode property, FALSE
if not.
Example #1 Testing different code points
<?php
var_dump ( IntlChar :: isUWhiteSpace ( "A" ));
var_dump ( IntlChar :: isUWhiteSpace ( " " ));
var_dump ( IntlChar :: isUWhiteSpace ( "\n" ));
var_dump ( IntlChar :: isUWhiteSpace ( "\t" ));
var_dump ( IntlChar :: isUWhiteSpace ( "\u{00A0}" ));
?>
以上例程会输出:
bool(false) bool(true) bool(true) bool(true) bool(true)
IntlChar::PROPERTY_WHITE_SPACE
