PHP: Using Zend to encrypt source code, Zend Guard installation and Zend Guard Run-time support mi_PHP tutorial

Zend Guard is the most mature PHP source code encryption product currently on the market.
I happened to need to encrypt my own products. After struggling for a whole night, I finally got it. I recorded the problems and solutions I encountered so that I can help others in the future.
I am using Wampserver, and the php version is 5.3.10.

Solution to Zend Guard Run-time support missing problem

Although the PHP source code can be successfully encrypted now, when executing the script, you will find that it cannot be executed normally and the following message will be displayed

Zend Guard Run-time support missing!
One more more files on this web site were encoded by ZendGuard and the required run-time support is not installed or properly configured.
......

It turns out that the encrypted php code requires the ZendGuardLoader module to run properly.
Because my php version is 5.3.10, I only provide ZendGuardLoader-php-5.3-Windows. If it is other versions of php, please Baidu.
Click to download ZendGuardLoader-php-5.3-Windows
After downloading, unzip the compressed package, find the ZendLoader.dll file in the directory, put it in the ext directory of your php directory, and then edit the php.ini file. Add a piece of code (eg):

[Zend.loader]
zend_loader.enable=1
zend_loader.disable_licensing=1
zend_loader.obfuscation_level_support=3
zend_loader.license_path=
zend_extension="Your PHP installation directory extZendLoader.dll"

Restart wampserver
If you are lucky, you will find that it can be grown and executed. If you are not lucky, you will still find the above error.
We have installed the zend guard loader here, why can’t we still execute the zend encrypted php script?
By looking at the output phpinfo() information, I found that there are several lines of information:

　　PHP Extension 20090626

　　Zend Extension 220090626

　　Zend Extension Build API220090626,TS,VC9

Please note that TS is the abbreviation of thread safety (i.e. thread safety)
I couldn’t find the reason for a while, so I simply opened the zend guard official website to search, and then it was solved.
It turns out that zend guard loader only supports the NTS version, which means that if your php version is TS, you cannot use zend guard loader. If you want to check whether your php is ts or nts, you only need to output phpinfo, and then search: Thread Safety, disabled corresponds to the nts version, otherwise it is ts.
Therefore, the ultimate solution is to download the php NTS version and install it.
