Sanitize string value to have only the given characters
You must provide a string of allowed characters in the $allow argument. If not provided then the only [ a-z A-Z 0-9 ] are allowed. You may optionally specify [alpha] to refer to any ASCII alphabet character, or [digit] to refer to any digit.
Available since version 3.0.126.
Example
echo $sanitizer->chars('foo123barBaz456', 'barz1'); // Outputs: 1baraz
echo $sanitizer->chars('(800) 555-1234', '[digit]', '.'); // Outputs: 800.555.1234
echo $sanitizer->chars('Decatur, GA 30030', '[alpha]', '-'); // Outputs: Decatur-GA
echo $sanitizer->chars('Decatur, GA 30030', '[alpha][digit]', '-'); // Outputs: Decatur-GA-30030Usage
// basic usage
$string = $sanitizer->chars(string $value);
// usage with all arguments
$string = $sanitizer->chars(string $value, $allow = '', string $replacement = '', bool $collapse = true, $mb = null);Arguments
