Regarding the problem of processing multiple consecutive backslashes in the PHP function stripslashes

php function: stripslashes()

Remove backslashes, function prototype string stripslashes (string $str), returns a string with escaped backslashes removed (' converted to ', etc.).

It is mentioned in the PHP official website that it returns a string with escaped backslashes removed (' converted to ', etc.). Double backslash (\) is converted into a single backslash (). In fact, this is inaccurate. My test should be the following result:

In the case of multiple consecutive backslashes, use it to escape There is no guarantee that there will be no backslashes in the return characters. For example, if there are three consecutive backslashes, one return will be retained. , after testing, the rule for removing backslashes by this function is: if there are two consecutive backslashes or less, all are removed; if there are more than two, subtract 2 and divide by 4, and then round to the nearest integer, such as 7 consecutive backslashes After being processed by it, the bars are: ceil((7-2)/4)=2, so in actual application, you can replace more than 3 consecutive backslashes with 3 and then use this function. Note that this issue is not mentioned on the official PHP website.
