how to get list of supported encodings by iconv library in php?

Question

Is it possible like in the mcrypt library with function mcrypt_list_algorithms(). Is there a iconv_list_encodings like function ?

Answer 1

In PHP the iconv extension does not have a function to list all available encodings.

The encodings which are available depends on which library iconv internally uses. For example there is libiconv. That website also contains a list of charsets you can use.

You can also connect to your server via SSH and execute the following command:

$ iconv -l 

This will give you the available list on that system if PHP is compiled against the same library as the command-line utility.

If you're uncertain if a specific charset is available, you need to check for errors by probing with iconv.
