IntlChar::isUWhiteSpace

(PHP 7)

IntlChar::isUWhiteSpace — Check if code point has the White_Space Unicode property

说明

public static bool IntlChar::isUWhiteSpace ( mixed $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() .

参数

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}")

返回值

Returns TRUE if codepoint has the White_Space Unicode property, FALSE if not.

范例

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)
