blocks|key|915540|text|感谢大家的算法等，我在维基百科上看到了。这是我根据上面的评论整理的版本。请注意，上面的版本存在问题，例如，对于vin，此00000000000354888返回OK。我采用了上面的内容，并添加了一个选项，如果<1980，则首先检查年份，假设它不是17位实数vin+(必须)，如果有单个字符的序列，则假定无效。这足以满足我的需要，因为我正在与长度为0(如果不是17+)的值进行比较。另外，我知道年份的值，所以如果我检查一下，我可以跳过vin检查来加快代码的速度(是的，我可以把它放在函数之前)，哈哈！|type|unstyled|depth|inlineStyleRanges|entityRanges|data|915541|++<?php

Thanks to all for the algorithm etc. which I see is on Wikipedia. This is the version I put together based on the comments above. Note, there are problems with the versions above, for ex this 00000000000354888 returns OK for a vin. I took what was above and added an option to check year first if &lt;1980, assume it isn't a 17digit real vin (have to), and also if there are sequences of a single character, assume invalid. This is good enough for my needs as I am comparing against values that are filled with 0s if not 17 in length. Also I know the year value so if I check that I can speed up the code by skipping the vin check (yes I could have put that in before the function) lol bye!.

Note that the wiki says:
&quot;A check-digit validation is used for all road vehicles sold in the United States and Canada.&quot;
So if you're working with other countries you might want to loosen the check-digit validation

had some good tips.

How can I validate a <a href="http://en.wikipedia.org/wiki/Vehicle_Identification_Number" rel="nofollow noreferrer">Vehicle Identification Number</a> with PHP? I just need to check if the entered VIN number is correct or not.
