What are some alternative approaches to accurately counting characters in a text area input in PHP without including spaces?

When counting characters in a text area input in PHP, spaces are often included in the count. To accurately count characters without including spaces, one approach is to use the `strlen()` function in combination with `str_replace()` to remove spaces before counting. This allows for an accurate character count excluding spaces. 

// Get the input text from the text area
$input_text = $_POST['input_text'];

// Remove spaces from the input text
$input_text_no_spaces = str_replace(' ', '', $input_text);

// Count the characters in the input text without spaces
$character_count = strlen($input_text_no_spaces);

echo "Character count (excluding spaces): " . $character_count;
