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 neveropen" Output : neveropen for neveropen Input : "chetna agarwal" Output : chetna agarwal
Below programs illustrate the lcfirst() function in PHP:
Program 1:
<?php // PHP program to demonstrates the // use of lcfirst() function $str = "Geeks for neveropen"; // converts the first character to // lower case and prints the string echo(lcfirst($str)); ?> |
Output:
neveropen for neveropen
Program 2: The program below demonstrates the use of lcfirst() function when the starting character is already in lower-case.
<?php // PHP program that demonstrates the // use of lcfirst() function when // the first case is already in lowercase $str = "chetna agarwal"; // already the first character is in lower case // so prints the same string only echo(lcfirst($str)); ?> |
Output:
chetna agarwal
