PHP Parse错误：语法错误，意外'？' [重复]

Question

This question already has an answer here:

• PHP parse/syntax errors; and how to solve them? 17 answers

I have read a lot syntax error but seldom on the error of '?'

I also saw a few post that stated this might be due to old PHP version.

So my question is does PHP5.6 isn't enough? I am using Godaddy as my host and PHP5.6 is the highest they provide.

The full error description is:

PHP Parse error: syntax error, unexpected '?' in G:\PleskVhosts\tohokiwatch.com\httpdocs\cart\vendor\illuminate\database\Eloquent\Model.php on line 579

MyPHP page stated version 5.5.30:

But my GoDaddy page stated version 5.6.30

Answer 1

The null coalesce operator, ?? does not exist in php 5.5 or 5.6, it was added in php 7.0
