IntlChar::hasBinaryProperty — Check a binary Unicode property for a code point

Beschreibung

public static bool IntlChar::hasBinaryProperty ( mixed $codepoint , int $property )

Checks a binary Unicode property for a code point.

Unicode, especially in version 3.2, defines many more properties than the original set in UnicodeData.txt.

The properties APIs are intended to reflect Unicode properties as defined in the Unicode Character Database (UCD) and Unicode Technical Reports (UTR). For details about the properties see » http://www.unicode.org/ucd/. For names of Unicode properties see the UCD file PropertyAliases.txt.

Parameter-Liste

codepoint

Der Integer-Wert des Codepoints (z.B. 0x2603 für U+2603 SNOWMAN) oder das Zeichen als UTF-8 String kodiert (z.B. "\u{2603}")

property

Die Unicode-Eigenschaft, die gesucht werden soll (siehe die IntlChar::PROPERTY_* Konstanten).

Rückgabewerte

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 version does not have data for the property at all, or not for this code point.

var_dump(IntlChar::hasBinaryProperty("[", IntlChar::PROPERTY_ALPHABETIC));
var_dump(IntlChar::hasBinaryProperty("[", IntlChar::PROPERTY_CASE_SENSITIVE));
