Setlocale (LC_ALL, 'zh _ cn') has been set. However, when reading csv files, you cannot read the Chinese characters in them. why? It seems to be related to the system!

Is the document encoding the same as the system encoding? if they are different, iconv converts the document encoding to the system encoding.

Fgetcsv has a BUG.

Use this function.

PHP code

Function _ fgetcsv (& $ handle, $ length = null, $ d = ',', $ e = '"') {$ d = preg_quote ($ d ); $ e = preg_quote ($ e); $ _ line = ""; $ eof = false; while ($ eof! = True) {$ _ line. = (empty ($ length )? Fgets ($ handle): fgets ($ handle, $ length); $ itemcnt = preg_match_all ('/'. $ e. '/', $ _ line, $ dummy); if ($ itemcnt % 2 = 0) $ eof = true;} $ _ csv_line = preg_replace ('/(? : | [])? $/', $ D, trim ($ _ line); $ _ csv_pattern ='/('. $ e.' [^ '. $ e.'] * (? :'. $ E. $ e. '[^ '. $ e. '] *) *'. $ e. '| [^ '. $ d. '] *)'. $ d. '/'; preg_match_all ($ _ csv_pattern, $ _ csv_line, $ _ csv_matches); $ _ csv_data = $ _ csv_matches [1]; for ($ _ csv_ I = 0; $ _ csv_ I <count ($ _ csv_data); $ _ csv_ I ++) {$ _ csv_data [$ _ csv_ I] = preg_replace ('/^ '. $ e. '(. *)'. $ e. '$/S',' $ 1', $ _ csv_data [$ _ csv_ I]); $ _ csv_data [$ _ csv_ I] = str_replace ($ e. $ e, $ e, $ _ csv_data [$ _ csv_ I]);} return empty ($ _ Line )? False: $ _ csv_data ;}
------ Solution --------------------
The bug of fgetcsv is that it cannot read Chinese characters...
------ Solution --------------------
Indeed, even if it is 5.3, the multi-byte support is still not very good.
------ Solution --------------------
It's actually a problem with php5.3.
