I have a website that used to have no problem running thinkphp with php7, but recently found that there was an error when I opened the CAPTCHA.

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

After searching on google baidu, there is still no solution.

So I did it myself, and it seemed that I was the first person to share it.

Reason:

One class uses the string class name, and php7 sets String as the keyword

Solution:

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

Find:

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

Modified 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 CAPTCHA came out. I searched it. There was no reference anywhere else. The problem was solved.
