PHP lcfirst() Function (original) (raw)

Last Updated : 21 Jun, 2023

The lcfirst() function is a built-in function in PHP which takes a string as an argument and returns the string with the first character in Lower Case and all other characters remain unchanged.

Syntax:

lcfirst($string)

Parameter: The function accepts only one parameter $string which is mandatory. This parameter represents the input string whose first character will be changed to lowercase.

Return Value: The function returns the same string only by changing the first character to lower case of the passed argument $string.

Examples:

Input : "Geeks for geeks" Output : geeks for geeks

Input : "chetna agarwal" Output : chetna agarwal

Below programs illustrate the lcfirst() function in PHP:

Program 1:

<?php

`` $str = "Geeks for geeks" ;

`` echo (lcfirst( $str ));

?>

Output:

geeks for geeks

Program 2: The program below demonstrates the use of lcfirst() function when the starting character is already in lower-case.

<?php

`` $str = "chetna agarwal" ;

`` echo (lcfirst( $str ));

?>
