What are some common challenges faced when trying to view the source code of PHP files?

When trying to view the source code of PHP files, common challenges include server configuration restrictions that prevent direct access to PHP files, file permissions that restrict viewing or downloading the files, and obfuscation techniques used to protect the code. To solve these issues, you can try adjusting server configurations, setting appropriate file permissions, or using tools to deobfuscate the code.

// Example code snippet to adjust server configuration to allow viewing PHP files
<Directory /path/to/your/php/files>
    Options +Indexes
    AllowOverride All
    Require all granted
</Directory>
