PHP - Update first character to upper using ucfirst

ucfirst can be used to update a string so that the first character is upper case. For example, let's say you have a variable that contains the text hello world.

$string = "hello world";


In this example, the first character in $string will be updated to upper.

$string = ucfirst($string);


Now, when you echo $string. . .

echo $string;


. . . the following will be displayed.

Hello world


Optionally, you could also use strtolower to first update the string to all lower case to guarantee that only the first character is upper.

$string = strtolower(ucfirst($string));
