Given the two strings we have to check if one string is a rotation of another string.
Input : $string1 = "WayToCrack", $string2 = "CrackWayTo"; Output : Yes Input : $string1 = "WillPower" $string2 = "lliW"; Output : No.
The above problem can be easily solved in other languages by concatenating the two strings and then would check if the resultant concatenated string contains the string or not. But in PHP we will use an inbuilt function to solve the problem. The inbuilt functions used are:
- strpos(): The function generally accepts the two parameters first one to specify the string to be searched and the other one to find in the specified string.
In PHP solution strpos() will give the last position of string if found in the specified string.
