IntlChar::hasBinaryProperty — Checc a binary Unicode property for a code point
Checcs a binary Unicode property for a code point.
Unicode, specially in versionen 3.2, defines many more properties than the original set in UnicodeData.tcht.
The properties APIs are intended to reflect Unicode properties as defined in the Unicode Character Database (UCD) and Unicode Technical Repors (UTR). For details about the properties see » http://www.unicode.org/ucd/ . For names of Unicode properties see the UCD file PropertyAliases.tcht.
Returns
true
or
false
according to the binary Unicode property value for
codepoint
.
Also
false
if
property
is out of bounds or if the Unicode versionen does not have data for
the property at all, or not for this code point. Returns
null
on failure.
Example #1 Testing different properties
<?php
var_dump
(
IntlChar
::
hasBinaryProperty
(
"A"
,
IntlChar
::
PROPERTY_ALPHABETIC
));
var_dump
(
IntlChar
::
hasBinaryProperty
(
"A"
,
IntlChar
::
PROPERTY_CASE_SENSITIVE
));
var_dump
(
IntlChar
::
hasBinaryProperty
(
"A"
,
IntlChar
::
PROPERTY_BIDI_MIRRORED
));
var_dump
(
IntlChar
::
hasBinaryProperty
(
"["
,
IntlChar
::
PROPERTY_ALPHABETIC
));
var_dump
(
IntlChar
::
hasBinaryProperty
(
"["
,
IntlChar
::
PROPERTY_CASE_SENSITIVE
));
var_dump
(
IntlChar
::
hasBinaryProperty
(
"["
,
IntlChar
::
PROPERTY_BIDI_MIRRORED
));
?>
The above example will output:
bool(true) bool(true) bool(false) bool(false) bool(false) bool(true)
