Example 2: Capitalizing the First Character After Trimming Whitespace

Use ucfirst() with trim() to capitalize the first character of a string that may contain leading whitespace.

$str = "   php tutorial";
$str = ucfirst(trim($str));
echo $str;  // Outputs: Php tutorial

Example 3: Handling Non-ASCII Characters

Since ucfirst() doesn’t handle multibyte characters, for non-ASCII strings, use *mb_ucfirst()*:

function mb_ucfirst($str) {
    return mb_strtoupper(mb_substr($str, 0, 1)) . mb_substr($str, 1);
}
echo mb_ucfirst("élève"); // Outputs: Élève
