What to note when using the Iconv function in PHP _php tutorial

Recently in a thief program, you need to use the ICONV function to crawl the UTF-8 encoded page into gb2312,

found that only using the ICONV function to fetch the data of a transcoding data will be less for no reason.

Let me depressed for a while, go online a check information to know this is a iconv function of a bug. Iconv error when converting character "-" to gb2312 phperz.com

The workaround is simply to add "//ignore" to the second parameter of the ICONV function after the code that needs to be converted.

The following is the referenced content:
Iconv ("UTF-8", "Gb2312//ignore", $data)

Ignore means ignoring errors at the time of conversion, and if there is no ignore argument, all strings after that character cannot be saved.
