Question: 1 / 400

What is the output of `strlen("Hello")` in PHP?

5

The function `strlen()` in PHP returns the length of a given string in bytes. When you call `strlen("Hello")`, it computes the number of characters in the string "Hello".

In this case, "Hello" consists of five letters: H, e, l, l, and o. Therefore, the output of `strlen("Hello")` is 5, which represents the total number of characters present in the string.

It's important to note that this function counts each character individually and does not include any hidden characters or special formatting unless they are part of the string itself. Thus, option A is the correct answer.
