PHP iconv solves the problem of utf-8 and gb2312 encoding conversion_PHP tutorial

Finally, Huangtian paid off and I found the answer.

This is how it is used on the Internet

This is actually correct. It looks like it is converting utf-8 to gb2312, but in actual operation, it is often run as It failed. What's the reason?

The reason is actually very simple, because any function will have an execution error, and unfortunately iconv(); will eventually cause an error. Now give you the correct answer.

The real answer is this



It’s very simple, just add //IGNORE after it, and adding this can be ignored by the ICONV() function Error, continue execution.

Similarly, to change gb2312 to utf-8, just write $content = iconv("gb2312","utf-8//IGNORE",$content);
