/**
 * Exports serializable PHP values to PHP code.
 *
 * VarExporter allows serializing PHP data structures to plain PHP code (like var_export())
 * while preserving all the semantics associated with serialize() (unlike var_export()).
 *
 * By leveraging OPcache, the generated PHP code is faster than doing the same with unserialize().

Consider adding parentheses for clarity. Current Interpretation: (! is_object($value) && ! is_array($value) && $value && ! is_resource($value)) || $value instanceof UnitEnum, Probably Intended Meaning: ! is_object($value) && ! is_array($value) && $value && (! is_resource($value) || $value instanceof UnitEnum)

The expression $value of type array is implicitly converted to a boolean; are you sure this is intended? If so, consider using empty($expr) instead to make it clear that you intend to check for an array without elements.

The type UnitEnum was not found. Maybe you did not declare it correctly or list all dependencies?
