protected function ConstraintValidator::formatValue in Plug 7

Returns a string representation of the value.

This method returns the equivalent PHP tokens for most scalar types (i.e. "false" for false, "1" for 1 etc.). Strings are always wrapped in double quotes ("). Objects, arrays and resources are formatted as "object", "array" and "resource". If the parameter $prettyDateTime is set to true, {@link \DateTime} objects will be formatted as RFC-3339 dates ("Y-m-d H:i:s").

Be careful when passing message parameters to a constraint violation that (may) contain objects, arrays or resources. These parameters should only be displayed for technical users. Non-technical users won't know what an "object", "array" or "resource" is and will be confused by the violation message.

Parameters

mixed $value The value to format as string:

int $format A bitwise combination of the format: constants in this class

Return value

string The string representation of the passed value
