PHP/4 尚未实现可见性。当它被添加到 PHP/5 中时，缺失的可见性关键字将成为
public的同义词，因此现有代码不会被破坏。如果它是遗留代码，我的建议是保持原样，直到您有机会检查代码并选择足够的可见性。如果它是新代码，您应该将其明确化。
PHP/4 did not implement visibility yet. When it was added in PHP/5, a missing visibility keyword was made synonym of
publicso existing code would not break.If it's legacy code, my advice is to leave it as is until you have the chance to review the code and pick an adequate visibility. If it's new code, you should make it explicit.
