IntlChar::islower — Check if code point is a lowercase letter
Determines whether the specified code point has the general category "Ll" (lowercase letter).
Nota:
This misses some characters that are also lowercase but have a different general category value. In order to include those, use IntlChar::isULowercase().
codepoint
Um codepoint integer (por exemplo 0x2603
para U+2603 SNOWMAN), ou um caracter codificado como uma string UTF-8 (exemplo "\u{2603}"
)
Returns true
if
codepoint
is an Ll lowercase letter, false
if not.
Exemplo #1 Testando codepoints diferentes
<?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"));
?>
O exemplo acima irá imprimir:
bool(false) bool(true) bool(false) bool(true) bool(false)
