IntlChar::isUWhiteSpace

(PHP 7)

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

说明

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

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 int 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

<?phpvar_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)
