PHP 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 indeed converting utf-8 to gb2312. But in actual operation, it often ends in failure. What is 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, just add this ICONV() function ignores errors and continues execution.

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