We can also use dynamic string here, which means that we have to get string from user and have to store that in a variable. Then we use our custom function on the variable in which we store string. And print the result using echo function.
7. We can also store the result in a variable and then use echo on them to print or display the required output. We hope you understand the above codes easily using these steps. For reference, you can see the above example to see how we done this.
