The token_name() function is an inbuilt function in PHP that is used to retrieve the textual representation of a given token identifier. In PHP, when you write code, it gets parsed into a series of tokens, which are the basic units of code that the interpreter understands. These tokens include keywords, operators, constants, variables, and other elements of the code.
Syntax:
string token_name(int $token)
Parameters: This function accepts only one parameter which is described below.
- $token: An integer representing a token constant.
Return Value: The token_name() function returns the symbolic name of the given token.
Program 1: The following program demonstrates the token_name() function.
PHP
<?php
$token = T_IF;
$tokenName = token_name( $token );
echo "Token name for $token: $tokenName" ;
?>
|

Token name for 322: T_IF
Program 2: The following program demonstrates the token_name() function.

$tokens = [T_IF, T_ECHO, T_FOREACH];
