Last Updated : 27 Aug, 2019

The IntlChar::charFromName() function is an inbuilt function in PHP which is used to find Unicode character by name and returns the code point value. If Unicode character name does not match to a code point, then it returns NULL. Syntax:

int IntlChar::charFromName( $characterName, $nameChoice = 
IntlChar::UNICODE_CHAR_NAME )

Parameters: This function accepts two parameters as mentioned above and described below:

$characterName: This parameter is used to hold the full Unicode character name.
$nameChoice: It is used to hold the names for lookup. The list of $nameChoice are given below:
- IntlChar::UNICODE_CHAR_NAME (default)
- IntlChar::UNICODE_10_CHAR_NAME
- IntlChar::EXTENDED_CHAR_NAME
- IntlChar::CHAR_NAME_ALIAS
- IntlChar::CHAR_NAME_CHOICE_COUNT

Return Value: This function returns the Unicode value of the code point on success or NULL if no code point exists. Below programs illustrate the IntlChar::charFromName() function in PHP: Example 1:

php

<?php

// PHP code to illustrate 
// IntlChar::charFromName ()function 
   
// Input symbol of codepoint  value  
// with constraint UNICODE_CHAR_NAME 
var_dump(IntlChar::charFromName("LATIN CAPITAL LETTER G"));

var_dump(IntlChar::charFromName("SNOWMAN"));

var_dump(IntlChar::charFromName("GEEKSFORGEEKS"));

var_dump(IntlChar::charFromName("^", IntlChar::CHAR_NAME_ALIAS )); 

?>

Output:

int(71)
int(9731)
NULL
NULL

Example 2:

php

<?php 

// PHP code to illustrate 
// IntlChar::charFromName() function 

// Declare an array $arr with constraint
// UNICODE_CHAR_NAME
$arr = array( 
            "LATIN CAPITAL LETTER G",
            "SNOWMAN",
            "GEEKSFORGEEKS"
        ); 

// Loop run for every array element 
foreach ($arr as $val) { 
    
    // Check each element as code point data 
    var_dump(IntlChar::charFromName($val));
} 
?>

Output:

int(71)
int(9731)
NULL
