Is base64_decode () prohibited?
No, base64 functions are not prohibited on our hosting. We have disabled some functions on our hosting, but those are mostly related to running system commands and other dangerous stuff.
What we don’t like is obfuscated code. base64_decode, especially when combined with eval, can be used to hide the actual function of PHP code and make it appear as gibberish. While this is not inherently dangerous, code obfuscation is usually done to hide viruses and other things you probably don’t want on your website (and we don’t want on our servers).
