IntlChar::isULowercase — Check if code point has the Lowercase Unicode property
$codepoint
)Check if a code point has the Lowercase Unicode property.
This is the same as IntlChar::hasBinaryProperty($codepoint, IntlChar::PROPERTY_LOWERCASE)
Note:
This is different than IntlChar::islower() and will return
TRUE
for more characters.
codepoint
The integer 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" ));
?>
以上例程会输出:
bool(false) bool(true) bool(false) bool(true) bool(false)
IntlChar::PROPERTY_LOWERCASE
