ucfirst(): Converting the first char to upper case
Uppercase the first character
ucfirst() uppercases the first ASCII lowercase letter when it appears at the start of the string. For broader Unicode-aware case conversion, use multibyte string functions.
$text = 'php tutorial';
echo ucfirst($text); // Php tutorial
Start with this current pattern. The examples below are retained, corrected where necessary, and expanded for additional variations and output.
$output=ucfirst($input_str);
| Parameter | DESCRIPTION |
|---|---|
| $input_str | Required : Input string |
Now let us try with one example
Here is a string variable $str with one string inside it. We will use ucfirst() to capitalize first chars of the string.
$str="welcome to plus2net.com";
$str=ucfirst($str);
echo $str;
Welcome To plus2net.com

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
