php XML轉換為數組的代碼

// Xml 轉 數組, 包括根鍵，忽略空元素和屬性，尚有重大錯誤 function xml_to_array( $xml ) { $reg = "/<(\\w+)[^>]*?>([\\x00-\\xFF]*?)<\\/\\1>/"; if(preg_match_all($reg, $xml, $matches)) { $count = count($matches[0]); $arr = array(); for($i = 0; $i < $count; $i++) { $key = $matches[1][$i]; $val = xml_to_array( $matches[2][$i] ); // 遞迴 if(array_key_exists($key, $arr)) { if(is_array($arr[$key])) { if(!array_key_exists(0,$arr[$key])) { $arr[$key] = array($arr[$key]); } }else{ $arr[$key] = array($arr[$key]); } $arr[$key][] = $val; }else{ $arr[$key] = $val; } } return $arr; }else{ return $xml; } } // Xml 轉 數組, 不包括根鍵 function xmltoarray( $xml ) { $arr = xml_to_array($xml); $key = array_keys($arr); return $arr[$key[0]]; } // 類似 XPATH 的數組選取器 function xml_array_select( $arr, $arrpath ) { $arrpath = trim( $arrpath, '/' ); if(!$arrpath) return $arr; $self = 'xml_array_select'; $pos = strpos( $arrpath, '/' ); $pos = $pos ? $pos : strlen($arrpath); $curpath = substr($arrpath, 0, $pos); $next = substr($arrpath, $pos); if(preg_match("/\\[(\\d+)\\]$/",$curpath,$predicate)) { $curpath = substr($curpath, 0, strpos($curpath,"[{$predicate[1]}]")); $result = $arr[$curpath][$predicate[1]]; }else $result = $arr[$curpath]; if( is_array($arr) && !array_key_exists($curpath, $arr) ) { die( 'key is not exists:' . $curpath ); } return $self($result, $next); } // 如果輸入的數組是全數字鍵，則將元素值依次傳輸到 $callback, 否則將自身傳輸給$callback function xml_array_each( $arr, $callback ) { if(func_num_args()<2) die('parameters error'); if(!is_array($arr)) die('parameter 1 shuld be an array!'); if(!is_callable($callback)) die('parameter 2 shuld be an function!'); $keys = array_keys($arr); $isok = true; foreach( $keys as $key ) {if(!is_int($key)) {$isok = false; break;}} if($isok) foreach( $arr as $val ) $result[] = $callback($val); else $result[] = $callback( $arr ); return $result; } ?> 複製代碼
