Answer 1

Answer:

PHP | strrev() Function

Reversing a string is one of the most basic string operations and is used very frequently by developers and programmers. PHP comes with a built-in function to reverse strings.

The strrev() function is a built-in function in PHP and is used to reverse a string. This function does not make any change in the original string passed to it as a parameter.

Synatx:

string strrev($inpString)

Parameter: This function accepts a single parameter $inpString. This parameter is a string and it specifies the string which we want to reverse. If a number is passed to it instead of a string, it will also reverse that number.

Return Value: The strrev() function returns the reversed string or the number. It does not make any change to the original string or number passed in the parameter.

Examples:

Input : $string = "geeks"  

Output : skeeg  

Input : $string = 143  

Output : 341  

Below programs illustrate the strrev() function in PHP:
