PHP token_name() Function

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
  
// Example token constant
$token = T_IF;
  
$tokenName = token_name($token);
  
echo "Token name for $token: $tokenName";
  
?>

Output

Token name for 322: T_IF

Program 2: The following program demonstrates the token_name() function.

PHP

<?php
  
// Example token constants
$tokens = [T_IF, T_ECHO, T_FOREACH]; 
  
foreach ($tokens as $token) {
    $tokenName = token_name($token);
    echo "Token name for $token: $tokenName\n";
}
  
?>

Output

Token name for 322: T_IF
Token name for 324: T_ECHO
Token name for 330: T_FOREACH
