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)
Note:
This is different than IntlChar::islower() and will return
true
for more characters.
codepoint
The int codepoint value (e.g. 0x2603
for U+2603 SNOWMAN), or the character encoded as a UTF-8 string (e.g. "\u{2603}"
)
Returns true
if
codepoint
has the Lowercase Unicode property, false
if not.
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"));
?>
The above example will output:
bool(false) bool(true) bool(false) bool(true) bool(false)
IntlChar::PROPERTY_LOWERCASE
