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)

<?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 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)); } ?> |
