Question: 1 / 400

How can you reverse a string in PHP?

By using the strrev() function

To reverse a string in PHP, the strrev() function is used. This built-in function takes a string as its input and returns the string with the order of the characters reversed. It is a straightforward and efficient way to accomplish this task without needing to implement additional logic or loops.

Other options, such as reverse_string(), do not exist in PHP’s standard function library, thus making them invalid choices. The implode() function is designed to concatenate array elements into a string rather than to reverse them. Similarly, str_replace() serves the purpose of replacing occurrences of a specified substring within a string, not reversing the string itself. Therefore, strrev() is the only appropriate and functional choice for reversing a string in PHP.
