How can the character length of a text input in PHP be determined using $_POST?

To determine the character length of a text input in PHP using $_POST, you can use the strlen() function to get the length of the input value. This function will return the number of characters in the input string. You can then use this value for validation or any other necessary processing. 

$input_text = $_POST['input_text'];

if(isset($input_text)){
    $length = strlen($input_text);
    echo "Character length of input text: " . $length;
}
