Here are ten logical questions for someone with 2 years of experience in PHP development:

1. Question: Given an array of integers, write a PHP function to find the two numbers that add up to a given target sum. If no such pair is found, return an appropriate message.
2. Question: Write a PHP script to determine whether a given string is a palindrome (reads the same backward as forward) or not.
3. Question: Create a PHP function that takes a string input and returns the count of each character present in the string, ignoring spaces and considering case-insensitivity.
4. Question: Write a PHP function to find the factorial of a given positive integer using both iterative and recursive approaches.
5. Question: Given two sorted arrays, write a PHP function to merge them into a single sorted array without using any built-in PHP sorting functions.

Remember, the complexity of the questions can be adjusted based on the level of experience you expect from the candidate. Logical questions like these help assess problem-solving skills and the ability to apply programming concepts to real-world scenarios.
