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
