如何使用PHP通配符?

I have a function that deletes a set of cookies on customer logout, my problem is that every time a cookie is deleted on logout - when the customer returns to the website and logs back in it is generated again, and when it's generated again a number is appended to the end.

Cookie Name's are generated as follows,

affiliate_account_code_1
affiliate_account_code_2
affiliate_account_code_3

and can go all the way up to the 100's.

My question is is there a way in PHP to say, if the string matches this criteria affiliate_account_code_* like using a wild card in the terminal? Is there a way to try and catch any number that is appended to the string.

After searching

PHP wildcard

I found that there is a fnmatch() function, having never used it I am unsure if it's suitable for the above.

我有一个在客户注销时删除一组cookie的功能,我的问题是每次删除一个cookie 注销时 - 当客户返回到网站并重新登录时,会再次生成,当再次生成时,会在末尾附加一个数字。

Cookie名称生成如下,

  affiliate_account_code_1 
affiliate_account_code_2 
affiliate_account_code_3 
   
 \  n 

并且可以一直到100.

我的问题是PHP中是否有一种方法可以说,如果字符串符合此条件 affiliate_account_code _ * < / code>喜欢在终端中使用外卡? 有没有办法尝试捕获附加到字符串的任何数字。

搜索后

PHP通配符

我发现有一个 fnmatch()函数,从未使用它我不确定它是否适合上述。

    This is easily possible with a regular expression and preg_match:

    preg_match('/affiliate_account_code_(\d+)/', $string, $matches);
    

    \d+ matches an infinite (at least one) number of digits. The match between the parentheses can be retrieved using $matches[1].

    Demo:

    php> $string = 'affiliate_account_code_1';
    'affiliate_account_code_1'
    php> preg_match('/affiliate_account_code_(\d+)/', $string, $matches);
    int(1)
    php> $matches;
    array (
      0 => 'affiliate_account_code_1',
      1 => '1',
    )
