On the problem of PHP function stripslashes for continuous multiple backslash processing

PHP functions: Stripslashes ()

Remove the backslash, function prototype string stripslashes (String $str), return a string after escaping the backslash (\ ' convert to ', etc.).

In the official PHP Web site, it is mentioned to return a string after removing the escape backslash (\ ' convert to ', etc.). The double backslash (\ \) is converted to a single backslash (\), which is actually inaccurate, and I should test for the following result:

In the case of multiple consecutive backslashes, escaping with it does not guarantee that there will be no backslash in the returned character, for example, a return is preserved with three consecutive backslashes. , after testing, the rule for this function to remove the backslash is: two consecutive and two are all removed, more than two are subtracted 2 divided by 4, into a method of rounding, such as 7 successive backslashes after it is processed: ceil ((7-2)/4) = 2, So in practical use, more than 3 consecutive backslashes can be replaced with 3 re-use this function. Note that this issue is not mentioned on the PHP official website.
