這幾天有在用simple_html_dom抓一些文章。不同網站的編碼在國內基本上是gbk gb2312 utf-8。而以gb2312和utf-8居多。我這一版的simple_html_dom有一個方法 convert_text 是這個樣子的。復制代碼 代碼如下: // PaperG - Function to convert the text from one character set to another if the two sets are not the same. function convert_text($text) { global $debug_object; if (is_object($debug_object)) {$debug_object- debug_log_entry(1);} $converted_text = $text; $sourceCharset = ""; $targetCharset = ""; if ($this- dom) { $sourceCharset = strtoupper($this- dom- _charset); $targetCharset = strtoupper($this- dom- _target_charset); } if (is_object($debug_object)) {$debug_object- debug_log(3, "source charset: " . $sourceCharset . " target charaset: " . $targetCharset);} if (!empty($sourceCharset) && !empty($targetCharset) && (strcasecmp($sourceCharset, $targetCharset) != 0)) { // Check if the reported encoding could have been incorrect and the text is actually already UTF-8 if ((strcasecmp($targetCharset, 'UTF-8') == 0) && ($this- is_utf8($text))) { $converted_text = $text; } else { $converted_text = iconv($sourceCharset, $targetCharset, $text); } } // Lets make sure that we don't have that silly BOM issue with any of the utf-8 text we output. if ($targetCharset == 'UTF-8') { if (substr($converted_text, 0, 3) == "/xef/xbb/xbf") { $converted_text = substr($converted_text, 3); } if (substr($converted_text, -3) == "/xef/xbb/xbf") { $converted_text = substr($converted_text, 0, -3); } } return $converted_text; } 來看這一行：復制代碼 代碼如下: $converted_text = iconv($sourceCharset, $targetCharset, $text); 會引起轉碼不正確。比如會把gb2312的文字轉成：復制代碼 代碼如下: 4月26日在 span 鏈濋槼 /span 公園馬術場舉行的2014浪琴國際馬聯場地障礙世界杯中國聯賽資格賽上，24歲的韓壯壯不僅拿到零罰分的成績 ...第7個出場的 span 鍖椾含 /span 奧運騎手趙志文第一個收獲零罰分，用時77秒07 ... 既成的事實了，證明里頭的轉碼功能沒有處理好。由于我使用這個simple_html_dom只是想要用來構建dom。我并沒有打算花時間去很好地處理這個bug。而是簡單地把復制代碼 代碼如下: $converted_text = iconv($sourceCharset, $targetCharset, $text); 改成復制代碼 代碼如下: $converted_text = $text; 就行了。思路就是取消它的轉碼。好吧工作不必糾結，可以繼續了。PHP教程
