[PHP] How to echo only the first carachter of a variable ?

[army20]

Hello All,

I have a very simple PHP script and I would like to "extract" or print or echo only the first letter of my variable. Is this possible ?

By exemple let's say my variable $_POST['profil'] return my first name, martin, I would like to have only the first letter so thaht would be the "m" in that case.

Thanks

-Martin

http://us2.php.net/manual/en/function.substr.php has two examples:

echo substr('abcdef', 1);	// bcdef
echo substr('abcdef', 1, 3);  // bcd
echo substr('abcdef', 0, 4);  // abcd
echo substr('abcdef', 0, 8);  // abcdef
echo substr('abcdef', -1, 1); // f

echo $string{0};				// a
echo $string{3};				// d
echo $string{strlen($string)-1}; // f

php.net is your friend.

<?php
$str = "Mary Had A Little Lamb and She LOVED It So";
$str = strtolower($str);
echo $str; // Prints mary had a little lamb and she loved it so
?>
