Question

我有一个像这样的数组

   $name=["Boxname,X1,X2,Y1,Y2,PID,GENDER,AGE,Bp_Systolic,Bp_Diastolic,X-Value,Y-Value", "LL, 53.3,106.6,33.300000000000004,59.947215189873425,22,MALE,63,Bp_Systolic,120,Bp_Diastolic,80"];

我想像这样转换它

$row = array (
    array('Boxname', 'X1', 'X2', 'Y2'),
    array('LL', '53.3', '106.6'),

);

任何人都可以告诉你如何做到这一点。我很困惑。请帮帮我！

Answer 1

你的问题有点不清楚，这是一个csv吗？您可以将其格式化为：Sample Output

$name=["Boxname,X1,X2,Y1,Y2,PID,GENDER,AGE,Bp_Systolic,Bp_Diastolic,X-Value,Y-Value", "Boxname:HH, X1:53.3, X2:106.6, Y1:33.300000000000004,Y2:59.947215189873425, PID:22, GENDER:MALE, Age:63,Bp_Systolic:120,Bp_Diastolic:80", "Boxname:HH, X1:53.3, X2:106.6, Y1:33.300000000000004,Y2:59.947215189873425, PID:27, GENDER:FEMALE, Age:56,Bp_Systolic:110,Bp_Diastolic:70"];

// get the headers (keys)
$headers = explode(',',array_shift($name));
$headers = array_splice($headers, 0, 10);
$data = array();
foreach($name as $info) {
    // explode by comma, then explode the headers inside the values
    $temp = array_map(function($piece){
        return explode(':', $piece)[1];
    }, explode(',', $info));
    $data[] = array_combine($headers, $temp); // combine the headers (keys) to the values
}

echo '<pre>';
print_r($data);

输出：

Array
(
    [0] => Array
    (
        [Boxname] => HH
        [X1] => 53.3
        [X2] => 106.6
        [Y1] => 33.300000000000004
        [Y2] => 59.947215189873425
        [PID] => 22
        [GENDER] => MALE
        [AGE] => 63
        [Bp_Systolic] => 120
        [Bp_Diastolic] => 80
    )

    [1] => Array
    (
        [Boxname] => HH
        [X1] => 53.3
        [X2] => 106.6
        [Y1] => 33.300000000000004
        [Y2] => 59.947215189873425
        [PID] => 27
        [GENDER] => FEMALE
        [AGE] => 56
        [Bp_Systolic] => 110
        [Bp_Diastolic] => 70
    )
)

如果您想要csv文件中的数据，那么只需使用fputcsv()函数：

$fp = fopen('your_csv_file.csv', 'w');
foreach($name as $fields) {
    $fields = explode(',', $fields);
    fputcsv($fp, $fields);
}

注意：您必须具有写入权限。

Answer 2

我认为这段代码会：

$name= array("Boxname,X1,X2,Y1,Y2,PID,GENDER,AGE,Bp_Systolic,Bp_Diastolic,X-Value,Y-Value", "Boxname:HH, X1:53.3, X2:106.6, Y1:33.300000000000004,Y2:59.947215189873425, PID:22, GENDER:MALE, Age:63,Bp_Systolic:120,Bp_Diastolic:80", "Boxname:HH, X1:53.3, X2:106.6, Y1:33.300000000000004,Y2:59.947215189873425, PID:27, GENDER:FEMALE, Age:56,Bp_Systolic:110,Bp_Diastolic:70");
foreach($name as $data){
    echo "<pre>";
    print_r(explode(",",$data));
    echo "</pre>";
}

输出：

Array
(
    [0] => Boxname
    [1] => X1
    [2] => X2
    [3] => Y1
    [4] => Y2
    [5] => PID
    [6] => GENDER
    [7] => AGE
    [8] => Bp_Systolic
    [9] => Bp_Diastolic
    [10] => X-Value
    [11] => Y-Value
)
Array
(
    [0] => Boxname:HH
    [1] =>  X1:53.3
    [2] =>  X2:106.6
    [3] =>  Y1:33.300000000000004
    [4] => Y2:59.947215189873425
    [5] =>  PID:22
    [6] =>  GENDER:MALE
    [7] =>  Age:63
    [8] => Bp_Systolic:120
    [9] => Bp_Diastolic:80
)
Array
(
    [0] => Boxname:HH
    [1] =>  X1:53.3
    [2] =>  X2:106.6
    [3] =>  Y1:33.300000000000004
    [4] => Y2:59.947215189873425
    [5] =>  PID:27
    [6] =>  GENDER:FEMALE
    [7] =>  Age:56
    [8] => Bp_Systolic:110
    [9] => Bp_Diastolic:70
)

Answer 3

试试这段代码。这很有效。

$var = '["Boxname,X1,X2,Y1,Y2,PID,GENDER,AGE,Bp_Systolic,Bp_Diastolic,X-Value,Y-Value", "Boxname:HH, X1:53.3, X2:106.6, Y1:33.300000000000004,Y2:59.947215189873425, PID:22, GENDER:MALE, Age:63,Bp_Systolic:120,Bp_Diastolic:80", "Boxname:HH, X1:53.3, X2:106.6, Y1:33.300000000000004,Y2:59.947215189873425, PID:27, GENDER:FEMALE, Age:56,Bp_Systolic:110,Bp_Diastolic:70"]';

$result = array();
$main_array = json_decode($var, true);
for($i = 0; $i < count($main_array); $i++){
    $temp_val = $main_array[$i];
    $curr_array = explode(",", $temp_val);
    $curr_temp_array = array();
    for($j = 0; $j < count($curr_array); $j++){
        $curr_item = explode(":", $curr_array[$j]);
        if(count($curr_item) == 1){
            $curr_temp_array[$j] =  $curr_array[$j];
        }else{
            $curr_temp_array[$curr_item[0]] = $curr_item[1];
        }
    }
    $result[$i] = $curr_temp_array;
}

var_dump($result);

这是输出：

  array(12) {

    string(7) "Boxname"
