PHP string Initial conversion Size Realistic Example _php tutorial

In PHP if we want to convert the characters to uppercase and lowercase, we can use Strtolower or strtoupper, but we need to use the ucwords correlation function to convert the case to the first letter.

First Letter capitalized: Ucwords ()

$foo = ' Hello world! '; $foo = Ucwords ($foo); Hello world! $bar = ' HELLO world! '; $bar = Ucwords ($bar); HELLO world! $bar = Ucwords (Strtolower ($bar)); Hello world! ?>

First word capitalized: Ucfirst ()

The code is as follows	Copy Code
$foo = ' Hello world! '; $foo = Ucfirst ($foo); Hello world! $bar = ' HELLO world! '; $bar = Ucfirst ($bar); HELLO world! $bar = Ucfirst (Strtolower ($bar)); Hello world! ?>
