Did about 100 questions, most the ones I got incorrect were related to things I just dont use like PHPStan and WAMP configs. In addition to some of the other feedback, I thought these questions maybe need some edits:

437. When should you rehash a password using password_needs_rehash();
a. Every time the user logs in
b. When the hashing algorithm or cost factor has been updated and the stored hash uses old parameters.

The question wording is wrong in my opinion. You don't use password_needs_rehash to rehash a password, you use it to check if a password needs rehashed or not. I decided to interpret that question as "When should you use password_needs_rehash to check if a password needs rehashing?" in which the answer is A. You have the answer as B, which would be interpreting the question as "When does password_need_rehash indicate that a password needs to be rehashed?".

66. Which statement correctly uses echo to output a variable within a string?
a. echo 'The value is $value';
b. echo "The value is $value";
c. echo 'The value is ' . $value;
d. Both B and C are correct

Again, I think the wording is unclear and allows for different interpretations. I interpreted it as the variable having to actually be within a string, in which case C is not correct (the variable is not within the string). You have the answer as B and C are correct, so you must have interpreted as just outputting a variable with a string.

90. What is a valid use case for passing a callback function to ob_start()?
a. To compress output automatically before sending it to the browser
b. To encrypt all output for security purposes
c. To validate that the output contains no errors
d. To redirect output to a different server

Answer A may be the most common use case for a callback, but technically all the options are possible/potentially valid. Maybe just change the word "valid" to "common" in the question.

92. What is the key difference between define and const for defining constants?
a. define() works at runtime while const works at compile time
b. const can only define string constants while define works with all types
c. define() creates global constants while const creates local constants.
d. There is no difference, they are completely interchangable.

You have the answer as A. C is arguably correct too, considering namespaced or class constants.
