IntlChar::isULowercase

IntlChar::isULowercase — Check if code point has the Lowercase Unicode property
说明
Check if a code point has the Lowercase Unicode property.
This is the same as IntlChar::hasBinaryProperty($codepoint, IntlChar::PROPERTY_LOWERCASE)
Note:
This is different than IntlChar::islower() and will return
TRUE
for more characters.
参数

var_dump(IntlChar::isULowercase("Φ"));
var_dump(IntlChar::isULowercase("φ"));
var_dump(IntlChar::isULowercase("1"));
