If (strtoupper (CHARSET) = 'gbk '&&! Empty ($ key )){
If (is_array ($ key )){
$ Result = var_export ($ key, true); // Convert it to a string
$ Result = iconv ('utf-8', 'gbk', $ result );
Eval ("\ $ result = $ result;"); // convert back to array
} Else {
$ Result = iconv ('utf-8', 'gbk', $ key );
}
}
Return $ result;
What does CHARSET in this sentence mean? Incredible. Is it a real test string?
And eval ("\ $ result = $ result;"); why can it be converted to an array?

The eval () function calculates the string according to the PHP code. Let's take a look at the introduction of this function in the manual.
------ Solution ----------------------
CHARSET is a constant. you can find the define ('charset', xxx); definition.
Eval is to convert the string into code for execution.
