(PHP 7)

IntlChar::isULowercase — Check if code point has the Lowercase Unicode property

### Description

public static bool IntlChar::isULowercase ( mixed `$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.

### Parameters

`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}")

### Return Values

Returns `TRUE` if `codepoint` has the Lowercase Unicode property, `FALSE` if not.

### Examples

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)
