php解析出带层级关系的mpp文件

本来要使用DHX gantt插件自带的API做导入，可是做完后，又发现不稳定，不能访问了

可能是屏蔽掉了

所以又想起可以使用javaBridge，借用java的MPXJ

1.简单输出所有任务

$file_path = "aa.mpp";
    require_once 'http://localhost:8089/JavaBridge/java/Java.inc';
    $data        = array();
    if (empty($file_path)) {
        return $data;
    }
    $mppRead     = new Java('net.sf.mpxj.mpp.MPPReader');
    $Filecontent = $mppRead->read($file_path);
    $Alltasks    = $Filecontent->getAllTasks();
    $Tasks_size  = java_values($Alltasks->size());
    for ($i = 1; $i < $Tasks_size; $i++) {
            $separator = '|';
            $tmp= getResource($Alltasks[$i]);
            $items = array();
            $items['id'] = $Alltasks[$i]->getID().'';
            $items['level'] = $Alltasks[$i]->getOutlineLevel().'';
            $items['uniqueID'] = $Alltasks[$i]->getUniqueID().'';
            $items['name'] = $Alltasks[$i]->getName().'';
            $items['duration'] = $Alltasks[$i]->getDuration().'';
            $items['start'] = $Alltasks[$i]->getStart().'';
            $items['finish'] = $Alltasks[$i]->getFinish().'';
            $items['percentComplete'] = $Alltasks[$i]->getPercentageComplete().'';
            $data[] = $items;
    }
    var_dump(json_encode($data));

这种解析的方式，忽略了微软Project允许用户创建的分层任务结构，虽然level可以表明他处于第几级

所以需要改进

2.输出带层级关系所有任务

将子任务放到children里

$file_path = "aa.mpp";
require_once 'http://localhost:8089/JavaBridge/java/Java.inc';
$data        = array();
if (empty($file_path)) {
    return $data;
}
$mppRead     = new Java('net.sf.mpxj.mpp.MPPReader');
$Filecontent = $mppRead->read($file_path);
$Alltasks    = $Filecontent->getChildTasks();
$Tasks_size  = java_values($Alltasks->size());
$data = array();
if($Tasks_size){
    $children = getChildren($Alltasks[0]);
    if($children){
        $data = $children;
    }
}
var_dump(json_encode($data));die;
function  getChildren($task){
    $child = $task->getChildTasks();
    $Tasks_size  = java_values($child->size());
    $data = array();
    $formatter = new Java('java.text.SimpleDateFormat', "yyyy-MM-dd HH:mm:ss"); 
    for ($i = 0; $i < $Tasks_size; $i++) {
            $separator = '|';
            $tmp= getResource($child[$i]);
            $items = array();
            $items['id'] = $child[$i]->getID().'';
            $items['level'] = $child[$i]->getOutlineLevel().'';
            $items['uniqueID'] = $child[$i]->getUniqueID().'';
            $items['name'] = $child[$i]->getName().'';
            $items['duration'] = $child[$i]->getDuration().'';
            $start = $child[$i]->getStart();
            $items['start'] = $formatter->format($start).'';
            $finish = $child[$i]->getFinish();
            $items['finish'] = $formatter->format($finish).'';
            $items['percentComplete'] = $child[$i]->getPercentageComplete().'';
            $children = getChildren($child[$i]);
            if($children){
                $items['children'] = $children;
            }
            $data[] = $items;
    }
    return $data;
}

解析后输出的json结构式带有层级关系的

说明：
　　$Alltasks = $Filecontent->getChildTasks();获取到的是文件的信息，一般就一个元素，

　　把$Alltasks[0]传给getChildren()获取的就是任务了

 $Alltasks    = $Filecontent->getChildTasks();
    $Tasks_size  = java_values($Alltasks->size());
    $formatter = new Java('java.text.SimpleDateFormat', "yyyy-MM-dd HH:mm:ss"); 
    for ($i = 0; $i < $Tasks_size; $i++) {
            $separator = '|';
            $tmp= getResource($Alltasks[$i]);
            $items = array();
            $items['id'] = $Alltasks[$i]->getID().'';
            $items['level'] = $Alltasks[$i]->getOutlineLevel().'';
            $items['uniqueID'] = $Alltasks[$i]->getUniqueID().'';
            $items['name'] = $Alltasks[$i]->getName().'';
            $items['duration'] = $Alltasks[$i]->getDuration().'';
            $start = $Alltasks[$i]->getStart();
            $items['start'] = $formatter->format($start).'';
            $finish = $Alltasks[$i]->getFinish();
            $items['finish'] = $formatter->format($finish).'';
            $items['percentComplete'] = $Alltasks[$i]->getPercentageComplete().'';
            $data[] = $items;
    }

    var_dump(json_encode($data));die;
