For our PhD program, we may face many problems as all topics related to the program are not know to us. Also, we may not get our supervisor in time, then we use online resource. But are all information correct?

Fung>> actually topics related to the PhD program unknown to us is good opportunity for new knowledge contribution. But you must thoroughly perform rigorous literature review to ensure that you don't reinvent the wheel.
Also, we may not get our supervisor in time,
Fung>> my personal experience in PhD pursuit is - rely more on yourself rather than your supervisor i.e. proactively do your best to handle / manage all the PhD related issues & only take supervisor as your reactive guide. Supervisor might not proactively guide you but you can. If you can't get your supervisor in time, try to proactively refer to other professor(s) that you can access or else can networking with other researchers / scholars in RG etc.
then we use online resource. But are all information correct?
Fung>> in order to evaluate the correctness / accuracy of online resources - try to source the online resource from multiple sources to triangulate their correctness / accuracy until appropriate saturation is reached.
For Ph.D students, they know exactly what they are looking for. Therefore, online resources are benefit for them. Maybe online resource for non-graduated students is not recommend. I think also that ultimately all collected data and information must discussed with supervisor.
online available resources need not necessarily be authentic or free from minor/ gross errors in content, so it is advisable to collect requisite material from multiple sources available and compare the contents , in case of ambiguity it is prudent to do a thorough self literature reading on the related material from related books/ journal articles and come to a conclusion.
if it is a formula/ computational procedure taken from online resources, it should be tested on one or more data-sets, results on which is already available by alternate methods/studies and results compared .
No, they are not, but you can avoid uncertainty by following some steps (most of which are mentioned by by the colleagues). You can make it simple this way:
For articles: consult only those which are published in peer blind reviewed journals. Search only within indexed journals and those with high impact factor.
For books: Be sure you consult those which are cited in previous research, in any field there are kind of (masterpieces) that are frequently referred to by most of the researchers but they are usually unavailable under open access or cc licences so they may be out of the scope of your question.
Try theses and dissertation repositories, you can trust most of them.
AVOID: articles from personal blogs, students' presentations (normally in ppt format) and graduation projects unless you check them against another trusted source. They normally lack proper documentation.
Last but not least, I think you will not take an information from one source for grant.. just DOUBLE CHECK!!
