val_to_string() public static method

converts all known PHP types into a string representation. Generally would be less verbose with objects and arrays than FUnit::var_export() because it uses json_encode()
public static val_to_string ( mixed $val, integer $maxlen = 50 ) : string
$val mixed the value to get as a string rep
$maxlen integer if > 0, truncate the string rep (default 50)
return string
