My question: I understand preg_replace (). This method requires three parameters: the first is a regular expression, the second is a string to be replaced, and the third is the template code, the replaced template code is returned. The first parameter in java reports an error. I don't know if the syntax is incorrect. if you want to use it in java, I hope you can give me some advice !! * ** Resolution template ** @ param $ str template content * @ returnture * publicfunction... regexphpjava
