Validate or sanitize a string to have a minimum length
If string meets minimum length it is returned as-is.
Note that the default behavior of this function is to validate rather than sanitize the value. Meaning, it will return blank if the string does not meet the minimum length. Specify the $padChar
argument to change that behavior.
If string does not meet minimum length, blank will be returned, unless a $padChar is defined in which
case the string will be padded with as many copies of that $padChar are necessary to meet the minimum
length. By default it padds to the right, but you can specify true for the $padLeft argument to make it pad to the left instead.
Example
$value = $sanitizer->minLength('foo'); // returns "foo"
$value = $sanitizer->minLength('foo', 3); // returns "foo"
$value = $sanitizer->minLength('foo', 5); // returns blank string
$value = $sanitizer->minLength('foo', 5, 'o'); // returns "foooo"
$value = $sanitizer->minLength('foo', 5, 'o', true); // returns "oofoo"Usage
// basic usage
$string = $sanitizer->minLength(string $value);
// usage with all arguments
$string = $sanitizer->minLength(string $value, int $minLength = 1, string $padChar = '', bool $padLeft = false);Arguments
