IntlChar::isULowercase — Check if code point has the Lowercase Unicode property
Check if a code point has the Lowercase Unicode property.
This is the same as IntlChar::hasBinaryProperty($codepoint, IntlChar::PROPERTY_LOWERCASE)
Nota:
This is different than IntlChar::islower() and will return
truefor more characters.
Returns true if
codepoint has the Lowercase Unicode property, false if not. Returns null on failure.
Example #1 Testing different code points
<?php
var_dump(IntlChar::isULowercase("A"));
var_dump(IntlChar::isULowercase("a"));
var_dump(IntlChar::isULowercase("Φ"));
var_dump(IntlChar::isULowercase("φ"));
var_dump(IntlChar::isULowercase("1"));
?>Il precedente esempio visualizzerà:
bool(false) bool(true) bool(false) bool(true) bool(false)
