How would you handle exceptions in PHP?
Exceptions in PHP are handled using a try, catch, and finally construct. The code that can potentially throw an exception is placed within the try block. The catch block contains the code that will be executed if an exception is thrown. The finally block contains code that will always be executed, regardless of whether an exception was thrown.
What are the different types of loops in PHP?
PHP supports four types of loops: for, while, do-while, and foreach. The for loop is used when you know how many times the script should run. The while loop runs as long as the specified condition is true. The do-while loop will always run at least once because the condition is not evaluated until after running the statements. The foreach loop works only on arrays and is used to loop through each key-value pair in an array.
Describe the difference between echo and print in PHP.
Both echo and print are used to output data to the screen. The differences are small: echo has no return value while print has a return value of 1 so it can be used in expressions. echo can take multiple parameters while print can take one argument. echo is slightly faster than print.
