IntlChar() functions provide access of utility methods which is used to access the information about Unicode characters. The IntlChar methods and constants are close to the names and behavior which are used by ICU (International Components for Unicode) library. 

Example: programs illustrate the IntlChar::charFromName() function in PHP

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
