Remove Whitespace from user input
I have a form which takes a name of a person. I have created a variable to contain the post array value.
$name = $_POST["name"];
I have also created a variable to contain the number of characters that is contained in the name.
$len = strlen($name);
when a user enters there full name the strlen function counts the white space is there a function that I can use that would only count the characters entered by the user?
For example my program would output "abc d" as 5 characters and not 4.

$len = strlen(preg_replace('/\s/', '', $name));

Or for faster results...
$characters= strlen(str_replace(' ', '', $name));

$characters= strlen(str_replace(' ', '', $name));
Thanks it worked. Why is this faster then the previous poster's suggestion?

Regular expressions use extra processing because it has to weed through the data with the given parameters. Now, say you wanted to check/change multiple (3 or more) items. In that case, preg_replace() would be faster. Read more about it here ( http://www.php-scripts.com/php_diary/011303.php3).
