SQL syntax issues in PHP
Answer
I just learned PHP today. I watched the tutorial from Chung Yuan University
Now I am writing that counter and I encountered a problem
The insertion command given by phpmyadmin is this
$sql = 'INSERT INTO `test`.`counter` (`new` )VALUES ('1')';
But when I write it into the php file, I get an error and it must be changed to
$sql = 'INSERT INTO `test`.`counter` (`new` )VALUES (1)';
Just remove the quotation marks around 1.
I saw that there are quotation marks in the video. Why can't there be quotation marks in my case?

Let me answer

I also think it’s a version issue, it seems I’ve encountered it before
