Question

我正在尝试输入从文件中检索数据获得的数组字符串。但它只读取第一个值。这就是我正在检索数据集的方式;

$file = explode("   ", file_get_contents("data/data-02"));
foreach ( $file as $content ) 
    {
        $result[] = array_filter(array_map("trim", explode("    ", $content)));
    }
//var_dump($result);
//echo $result[0][1];
    $time = '';
    for ($id = 1; $id < 20; $id+= 6)
    {
        $time .=  '"'.$result[0][$id].'"'.',';
    }
    $sugar_1 = '';
    for ($id = 2; $id <20; $id+=6)
    {
        $sugar_1 .= $result[0][$id].',';
    }
    $sugar_2 = '';
    for ($id = 5; $id <20; $id+=6)
    {
        $sugar_2 .= $result[0][$id].',';
    }

离。 echo sugar_1是

58,60,62,48,58,60,62,48,58,62,48,58,60,62,48,58,60,62,48,58,60,62,48,58 ，60,62,48,58,60,62,48,58,60，

现在我想把它输入

/* pChart library inclusions */ 
 include("pChart/class/pData.class.php"); 
 include("pChart/class/pDraw.class.php"); 
 include("pChart/class/pImage.class.php"); 

 /* Create and populate the pData object */ 
 $MyData = new pData();   
 $MyData->addPoints(array($sugar_1),"Probe 1"); 
 $MyData->addPoints(array($sugar_2),"Probe 2"); 
 $MyData->setSerieTicks("Probe 2",4); 
 $MyData->setAxisName(0,"Sugar level in blood"); 
 $MyData->addPoints(array($time),"Labels"); 
 $MyData->setSerieDescription("Labels","Hours"); 
 $MyData->setAbscissa("Labels");

但正如我所说，它只是读取第一个值，但是例如，如果我要在那里添加smth

$MyData->addPoints(array($sugar_1**,44,66**),"Probe 1");然后这些增值非常有效。我出类拔萃了。

解决。

header("Content-type:text/plain");
$file = fopen("data/data-02", "r");

$result = array();
$file = explode("   ", file_get_contents("data/data-02"));
foreach ( $file as $content ) 
    {
        $result[] = array_filter(array_map("trim", explode("    ", $content)));
    }
//var_dump($result);
//echo $result[0][1];
$time = array();
$k=0;
    for ($id = 1; $id < 31; $id+= 6)
    {
        $time[$k] =  '"'.$result[0][$id].'"'.',';
        $k++;
    }
    $sugar_1 = array();
    $k=0;
    for ($id = 2; $id <30; $id+=6)
    {
        $sugar_1[$k] = $result[0][$id].',';
        $k ++;
    }
    $sugar_2 = array();
    $k=0;
    for ($id = 5; $id <33; $id+=6)
    {
        $sugar_2[$k] = $result[0][$id].',';
        $k++;
    }

 /* pChart library inclusions */ 
 include("pChart/class/pData.class.php"); 
 include("pChart/class/pDraw.class.php"); 
 include("pChart/class/pImage.class.php"); 

 /* Create and populate the pData object */ 
 $MyData = new pData();   
 $MyData->addPoints($sugar_1,"Probe 1"); 
 $MyData->addPoints($sugar_2,"Probe 2"); 
 $MyData->setSerieTicks("Probe 2",4); 
 $MyData->setAxisName(0,"Sugar level in blood"); 
 $MyData->addPoints($time,"Labels"); 
 $MyData->setSerieDescription("Labels","Hours"); 
 $MyData->setAbscissa("Labels");

数组中的pChart输入
