How to fix Syntax error, unexpected '' (T_STRING)? - php

Question

The error that I am receiving is this: Parse error: syntax error, unexpected 'TokenType' (T_STRING) in C:\Program Files\Ampps\www\cs5339\lepichardo\4339_f22_assignment1\TokenType.php on line 2. To be clear, both files are php, and they both are in the same director. The code below is where I include the enum TokenType so that I would be able to use it.
<?php
include 'TokenType.php'
?>
The TokenType.php looks like this
<?php
enum TokenType{
case INT;
case STRING;
case COMMA;
}
?>
As far as I now, this should be fine, but gives me that error in that particular line.
If there is any other way to declare and imlpement the enum variable in php I would like to be explained to how to. Thanks in advance!!!

Answer 1

enums are only available in PHP 8.1+. The error suggests you are running PHP 7.
Here's some results of running the following code using various PHP versions (using https://3v4l.org/qHU4f)
<?php
enum TokenType{
case INT;
case STRING;
case COMMA;
}
echo 'hello world';
Output for 8.1.0 - 8.1.11, 8.2rc1 - rc3
hello world
Output for 8.0.1 - 8.0.24
Parse error: syntax error, unexpected identifier "TokenType" in /in/qHU4f on line 2
Process exited with code 255.
Output for 7.4.0 - 7.4.32
Parse error: syntax error, unexpected 'TokenType' (T_STRING) in /in/qHU4f on line 2
Process exited with code 255.
As you can see by the last result, unexpected 'TokenType' (T_STRING) is an error you would receive in PHP 7
