Make a string's first character as uppercase - PHP
To make a string’s first character as uppercase, we can use a PHP function called ucfirst.
string ucfirst ( string $string )
Returns a string with the first character of $string capitalized, if that character is alphabetic.
Example
$foo = 'hello world!';
$foo = ucfirst($foo); // Hello world!
$bar = 'HELLO WORLD!';
$bar = ucfirst($bar); // HELLO WORLD!
$bar = ucfirst(strtolower($bar)); // Hello world!
