I have a website before using PHP7 run thinkphp no problem, but recently found to open the verification code when found to have errors

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

Google Baidu search for a bit or no workaround

So I was the first one to share it.

Reason:

There is a class with the string class name, PHP7 string as the keyword

Workaround:

File thinkphp\library\org\util\image.class.php

Found it:

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

Modified to:

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

To copy a 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 the verification code out, I searched for it. No other references, this problem solved
