PHP ucfirst() Function

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

ucfirst($string)

Parameter: The function accepts only one parameter $string which is mandatory. This parameter represents the string whose first character will be changed to uppercase. Return Value: The function returns the same string only by changing the first character to upper case of the passed argument $string. Examples:

 Input : "geeks for geeks" Output : Geeks for geeks Input : "Chetna Agarwal" Output : Chetna Agarwal

<?php // PHP program that demonstrates the  // use of ucfirst() function  $str = "geeks for geeks"; // converts the first case to upper case  // and prints the string echo(ucfirst($str)); ?>

Program 2: The program below demonstrates the use of ucfirst() function when the starting character is in upper-case. php

<?php // PHP program that demonstrates the  // use of ucfirst() function when  // the first case is already in uppercase $str = "Chetna Agarwal"; // already the first character is in upper case  // so prints the same string only echo(ucfirst($str)); ?>
