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 ));
?>
|
Output:
chetna agarwal
