Whenever I add in PHP code in my HTML file, (using MAMP) I got this HTTP ERROR 500 warning

[mrchow19910319]

I have set up MAMP on my macbook pro.
However right now if I write any sort of PHP file into the htdocs file, or write any sort of PHP code inside my HTML file, I got this error message:

 

 

If I remove all of my PHP code, the error message disappear. 

Where did it go wrong??

Are you using <?php ?> opening and closing tags, and if not, is it in a <script> and closed?

it's going to be hard to give an answer without an error log: https://stackoverflow.com/questions/8641383/how-can-i-get-mamp-to-tell-me-what-went-wrong-with-php-code

 

As a general rule, when you run into issues your first step is almost always to find the stack trace to try and get more insight. "error 500" is INCREDIBLY broad, and you need some more info before you know for sure whats wrong. Otherwise you are just taking shots in the dark, which is the debugging equivalent of trying to hit a home run with a blindfold unless you already have some deep intuitions of the code you're working with.

I can only assume you've already made a connection.php file?

 

EDIT: If not, you have to make a connection.php file that links your database, user and pass, and the database name. I can only see two files open. your .css and your html file

All good mate,

 

if you get stuck:

Pretty obvious, try to add line by line because it seems you forget to add some ";" there

 

For example after $db variable and $msg variable.

 

Don't write all of it just do line by line and test if you just began
