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 : "neveropen for neveropen" Output : Geeks for neveropen Input : "Chetna Agarwal" Output : Chetna Agarwal
Below programs illustrate the ucfirst() function in PHP:
Program 1: The program below demonstrates the use of ucfirst() function.
<?php     // PHP program that demonstrates the     // use of ucfirst() function           $str = "neveropen for neveropen";           // converts the first case to upper case     // and prints the string     echo(ucfirst($str)); ?> |
Output:
Geeks for neveropen
Program 2: The program below demonstrates the use of ucfirst() function when the starting character is in upper-case.
<?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)); ?> |
Output:
Chetna Agarwal
[…] To convert the first character of all the words present in a string to uppercase, we just need to use one PHP function i.e. ucwords(). […]
