I have a website that used php7 to run thinkphp without any problems, but recently I found an error when turning on the verification code

Cannot use 'String' as class name as it is reserved

After searching on google baidu, there is still no solution

So I solved it myself. It seems that I am the first person to share it

Reason:

There is a class that uses the string class name, and php7 sets String as Keyword

Solution:

File ThinkPHP\Library\Org\Util\Image.class.php

Found:

import('ORG.Util.String');
$code = String::rand_string($length, 4);

Change to:

import('ORG.Util.Stringnew');
$code = Stringnew::rand_string($length, 4);

Copy the file:

ThinkPHP\Library\Org\Util\String.class.php

Save as:

ThinkPHP\Library\Org\Util\Stringnew.class.php

Open Stringnew.class.php:

class String {

Modified to:

class Stringnew {

Put it up and the verification code comes out. I searched and found no other references. This problem is solved
