IntlChar::islower — Check if code point is a lowercase letter
Description
public static bool IntlChar::islower ( mixed $codepoint )
Determines whether the specified code point has the general category "Ll" (lowercase letter).
Note: This misses some characters that are also lowercase but have a different general category value. In order to include those, use IntlChar::isULowercase().
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 is an Ll lowercase letter, FALSE if not.
Examples
Example #1 Testing different code points
<?php
var_dump(IntlChar::islower("A")
var_dump(IntlChar::islower("a")
var_dump(IntlChar::islower("Φ")
var_dump(IntlChar::islower("φ")
var_dump(IntlChar::islower("1")
?>
The above example will output:
bool(false)
bool(true)
bool(false)
bool(true)
bool(false)
