IntlChar::isUWhiteSpace
Check if code point has the White_Space Unicode property
Description
public static boolnull IntlChar::isUWhiteSpace(intstring $codepoint
)
This is the same as IntlChar::hasBinaryProperty($codepoint, IntlChar::PROPERTY_WHITE_SPACE)
Note:
This is different from both IntlChar::isspace and IntlChar::isWhitespace.
Parameters
-
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}"
)
Return Values
Returns true
if
codepoint
has the White_Space Unicode property, false
if not. Returns null
on failure.
Examples
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}"));
?>
The above example will output:
bool(false)
bool(true)
bool(true)
bool(true)
bool(true)
