IntlChar::isUWhiteSpace()

版本：php7

(PHP 7)

Check if code point has the White_Space Unicode property

说明

publicstaticIntlChar::isUWhiteSpace(mixed $codepoint): bool

Check if a code point has the White_Space Unicode property.

This is the same asIntlChar::hasBinaryProperty($codepoint, IntlChar::PROPERTY_WHITE_SPACE)

Note:

This is different from both IntlChar::isspace() and IntlChar::isWhitespace().

参数

$codepoint

The integer codepoint value(e.g.0x2603forU+2603 SNOWMAN), or the character encoded as a UTF-8 string(e.g."u{2603}")

返回值

Returns TRUE if$codepointhas the White_Space Unicode property,FALSE if not.

范例

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)
