IntlChar::hasBinaryProperty
(PHP 7, PHP 8)
Check a binary Unicode property for a code point
Description
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 Ucd. For names of Unicode properties see the UCD file PropertyAliases.txt.
Parameters
codepointParameter
propertyParameter
Return Values
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. Returns null on failure.
