adding a function to php.ini

Question

I used the function htmlentities() in my php script, but the server says: "undefined function"

After some searching, I understand that the php installation on my webhost does not include that function, and that I can add the function by changing the php.ini file, but I have spent many hours searching, and have not found any information on how to actually do this.

Any suggestions?

Answer 1

If your webhost's PHP install doesn't have something so basic as htmlentities() , it's time to get a new webhost. If it's that bizarrely locked down, you're also not likely to be able to tweak php.ini ...

Answer 2

我在手册中没有看到任何说明该功能在您启用的可选模块中的内容-您只需要PHP 4或5。确定要调用正确的功能吗？

Answer 3

It's surprising that this would be unavailable, but have you tried the alternate htmlspecialchars? It will deal with the ones that are most important to deal with.
