How to Reverse a String in PHP

In PHP, you can reverse a string using the strrev() function. Here is an example code showing how to reverse a string using the strrev() function:

$str = "Hello, World!";
$reversedStr = strrev($str);

echo $reversedStr; // 输出：!dlroW ,olleH

In the above example, we start by defining a string $str, then use the strrev() function to reverse it and store the result in the $reversedStr variable. Finally, we output the reversed string using echo.

Utilizing the strrev() function is a very simple and convenient way to reverse a string in PHP.
