PHP | IntlChar::totitle() Function

Last Updated : 12 Feb, 2021

The IntlChar::totitle() function is an inbuilt function in PHP which is used to check whether the input code point is a Unicode character titlecase or not.
Syntax:

mixed IntlChar::totitle( $codepoint )

Parameters: This function accepts a single parameter $codepoint which is mandatory. The $codepoint parameter is a character or integer value, which is encoded as a UTF-8 string.
Return Value: Returns the simple_Titlecase_Mapping of the code point, if any; otherwise the code point itself. The return type will be an integer unless the code point was passed as a UTF-8 string, in which case a string will be returned.
Below programs illustrate the IntlChar::totitle() Function in PHP:
Program 1:

php

<?php
// PHP function to illustrate the
// use of IntlChar::totitle()
  
// Input Capital letter  codepoint
var_dump(IntlChar::totitle("G"));
 
// Input Capital letter  codepoint
var_dump(IntlChar::totitle("g"));
 
// Input Capital letter  codepoint
var_dump(IntlChar::totitle("a"));
 
// Input int char an identifier
// of codepoint value
var_dump(IntlChar::totitle("\u{00A0}"));
  
// Input symbolic space codepoint value 
var_dump(IntlChar::totitle(" "));
 
// Input symbolic codepoint value 
var_dump(IntlChar::totitle(" ^ "));
 
// Input int codepoint value 
var_dump(IntlChar::totitle("9"));
 
// Input control character codepoint value 
var_dump(IntlChar::totitle("\n"));
 
// Input character value
// return its ASCII value
var_dump(IntlChar::totitle(ord("D")));
var_dump(IntlChar::totitle(ord("d")));
 
// Input  ASCII value 0054 is "T"
var_dump(IntlChar::totitle(ord("0054")));
var_dump(IntlChar::totitle(ord("@")));
 
?>

Output:

string(1) "G" 
string(1) "G" 
string(1) "A" 
string(2) " " 
string(1) " " 
NULL 
string(1) "9" 
string(1) " " 
int(68) 
int(68) 
int(48) 
int(64)

Program 2:

php

<?php
// PHP function to illustrate the
// use of IntlChar::totitle()
 
// Declare an array with
// different codepoint value 
$arr = array("X",
            "x", 
            "*",
            "8",
            "0",
            " ",               
        );
   
// For loop condition to check 
// each character through function
foreach ($arr as $val) {
       
    // Check each element as code point data
    var_dump(IntlChar::totitle($val));
}
?>

Output:

string(1) "X"
string(1) "X"
string(1) "*"
string(1) "8"
