How can PHP functions be used to exclude specific characters from input text?

To exclude specific characters from input text using PHP functions, you can use the `str_replace()` function to replace the unwanted characters with an empty string. This function takes three parameters: the character(s) to be replaced, the replacement character (in this case, an empty string), and the input text. By using `str_replace()`, you can effectively filter out the unwanted characters from the input text. 

$input_text = "This is some input text with unwanted characters!@#";
$unwanted_chars = array("!", "@", "#");

$cleaned_text = str_replace($unwanted_chars, "", $input_text);

echo $cleaned_text;
