IntlChar::isUWhiteSpace — Check if code point has the White_Space Unicode property
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().
Returns true
if
codepoint
has the White_Space Unicode property, false
if not. Returns null
on failure.
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)
IntlChar::PROPERTY_WHITE_SPACE
