IntlChar::totitle — Make Unicode character titlecase
The given character is mapped to its titlecase equivalent. If the character has no titlecase equivalent, the original character itself is returned.
Returns the Simple_Titlecase_Mapping of the code point, if any;
otherwise the code point itself. Returns null
on failure.
The return type is int unless the code point was passed as a UTF-8 string, in which case a string is returned. Returns null
on failure.
Example #1 Testing different code points
<?php
var_dump(IntlChar::totitle("DŽ"));
var_dump(IntlChar::totitle("dž"));
var_dump(IntlChar::totitle("Φ"));
var_dump(IntlChar::totitle("φ"));
var_dump(IntlChar::totitle("1"));
var_dump(IntlChar::totitle("ᾳ");
var_dump(IntlChar::totitle(ord("A")));
?>
The above example will output:
string(1) "Dž" string(1) "Dž" string(2) "Φ" string(2) "φ" string(1) "1" string(1) "ᾼ" int(65)
