Reverse a string in PHP is pretty simple. PHP provides inbuilt function to reverse a string PHP: strrev - Manual but knowing the logic of how it works is very simple and interesting. In the interview you may come across "Write a PHP function which should reverse the given string, condition u should not use strrev (inbuilt) function and array functions ". You can answer this question with few steps,
- Assign the given string to the variable
- Calculate the length of the string
- Declare a variable in which you have to store the reversed string
- Iterate the string using for loop with appropriate looping and count
- Concatenate the string inside the for loop
- Display the reversed string.
The below code snippets shows the PHP code to reverse a sting without Array and strrev(inbuilt) function.
