проблема с массивом php str_getcsv

Question

Я загружаю CSV-файл, а затем анализирую его с помощью str_getcsv. Все прекрасно работает, за исключением того, что мне нужен способ их циклически проходить В идеале было бы здорово, чтобы массив возвращался и выглядел так:

Array (      
    [1] => Array
       (
            [0] => 1 // first id in csv
            [1] => name
            [2] => address
            [3] => town
            [4] => state
            [5] => zip
            [6] => phone
            [7] => website
            [8] => other
            [9] => other
        )
    [22] => Array
       (
            [10] => name
            [11] => address
            [12] => town
            [13] => state
            [14] => zip
            [15] => phone
            [16] => website
            [17] => other
            [18] => other
        )
    [24] => Array
       (
            [19] => name
            [20] => address
            [21] => town
            [22] => state
            [23] => zip
            [24] => phone
            [25] => website
            [26] => other
            [27] => other
        )
)

Однако данные возвращаются следующим образом:

Array
(
    [0] => 1 // first id in csv
    [1] => name
    [2] => address
    [3] => town
    [4] => state
    [5] => zip
    [6] => phone
    [7] => website
    [8] => other
    [9] => other
22 // id field
    [10] => name
    [11] => address
    [12] => town
    [13] => state
    [14] => zip
    [15] => phone
    [16] => website
    [17] => other
    [18] => other
24// id field
    [19] => name
    [20] => address
    [21] => town
    [22] => state
    [23] => zip
    [24] => phone
    [25] => website
    [26] => other
    [27] => other

Любые предложения о том, как это исправить, чтобы выглядеть как массив в верхней части? щас делаю:

$csvfile = file_get_contents($targetFile);
$csv = str_getcsv($csvfile);

Answer 1

str_getcsv () ожидает, что строка, переданная в качестве параметра, будет одна запись.
Но так как ваш источник в любом случае является файлом, самый простой способ, вероятно, использовать fgetcsv () вместо str_getcsv ()

$data = array();
$fp = fopen($targetFile, 'rb');
while(!feof($fp)) {
    $data[] = fgetcsv($fp);
}
fclose($fp);

автономный пример:

<?php
$targetFile = 'soTest.csv';
setup($targetFile);

$data = array();
$fp = fopen($targetFile, 'rb');
while(!feof($fp)) {
    $data[] = fgetcsv($fp);
}
var_dump($data);


function setup($targetFile) {
    file_put_contents($targetFile, <<< eot
1,name,address,town,state,zip,phone,website,other,other
2,name,address,town,state,zip,phone,website,other,other
3,name,address,town,state,zip,phone,website,other,other
eot
    );
}

array(3) {
  [0]=>
  array(10) {
    [0]=>
    string(1) "1"
    [1]=>
    string(4) "name"
    [2]=>
    string(7) "address"
    [3]=>
    string(4) "town"
    [4]=>
    string(5) "state"
    [5]=>
    string(3) "zip"
    [6]=>
    string(5) "phone"
    [7]=>
    string(7) "website"
    [8]=>
    string(5) "other"
    [9]=>
    string(5) "other"
  }
  [1]=>
  array(10) {
    [0]=>
    string(1) "2"
    [1]=>
    string(4) "name"
    [2]=>
    string(7) "address"
    [3]=>
    string(4) "town"
    [4]=>
    string(5) "state"
    [5]=>
    string(3) "zip"
    [6]=>
    string(5) "phone"
    [7]=>
    string(7) "website"
    [8]=>
    string(5) "other"
    [9]=>
    string(5) "other"
  }
  [2]=>
  array(10) {
    [0]=>
    string(1) "3"
    [1]=>
    string(4) "name"
    [2]=>
    string(7) "address"
    [3]=>
    string(4) "town"
    [4]=>
    string(5) "state"
    [5]=>
    string(3) "zip"
    [6]=>
    string(5) "phone"
    [7]=>
    string(7) "website"
    [8]=>
    string(5) "other"
    [9]=>
    string(5) "other"
  }
}

edit2: Для использования первого элемента каждой записи в качестве ключа в массиве результатов:

<?php
$targetFile = 'soTest.csv';
setup($targetFile);

$data = array();
$fp = fopen($targetFile, 'rb');
while(!feof($fp)) {
    $row = fgetcsv($fp);
    $id = array_shift($row);
    $data[$id] = $row;
}
var_dump($data);


function setup($targetFile) {
    file_put_contents($targetFile, <<< eot
1,name,address,town,state,zip,phone,website,other,other
2,name,address,town,state,zip,phone,website,other,other
3,name,address,town,state,zip,phone,website,other,other
eot
    );
}

Answer 2

Ну, просто посчитайте количество элементов в записи, затем сделайте цикл внутри цикла

// loop on all items; $i+=$ITEM_SIZE go to the next item each outer loop
// (10 elements for ITEM in Opening Post's case)

// this for loops between all items
for ($i=0;$i<=$ARRAY_LENGHT;$i+=10)
{
    // this for loops between each item's elements
    for($c=1; $c<=10;$c++)
    {
        switch($c)
        {
            case 1:
              $id = $array[$i+$c];
              break;

            case 2:
              $name = $array[$i+$c];
              break;

            case 3:
              $address = $array[$i+$c];
              break;

            //etc to 10th element:

            case 10:
              $other = $array[$i+$c];
              break;

        }
    }

    // When the item is all done use the item
    // it as you need, example:

    echo "id: {$id}\nname: {$name}\naddress: {$adress}"; //etc

    // then unset($id,$name,$address, $etc);
    // for the next iteration of loop (next item)
}

Это то, что я только что сделал и работает очень хорошо.

Answer 3

Не самая милая вещь в этом мире, но я думаю, что это работает.

<code>//make the arrays needed
$csvtmp = array();
$csvFinal = array();

$csvfile = file_get_contents('test.csv');
$csv = str_getcsv($csvfile,"\n"); //make an array element for every record (new line)

//Loop through the result 
foreach ($csv as $key => $item) 
{
    array_push($csvtmp, str_getcsv($item,";")); //push each record to the csv temp array

    //here's the messy part. This set the key of the csvFinal array to the first field in the current record and for the value it gives it the array we got from the previous str_getcsv.
    $csvFinal[$csvtmp[$key][0]] = $csvtmp[$key]; 
    //Here we just unset the id row in the final array
    unset($csvFinal[$csvtmp[$key][0]][0]);

}

echo "<pre>";
    print_r($csvFinal);
echo "

";

результат кода:

Array
(
    [22] => Array
        (
            [1] => name1
            [2] => address1
            [3] => town1
            [4] => state1
            [5] => zip1
            [6] => phone1
            [7] => website1
            [8] => other1
            [9] => other1
        )

    [23] => Array
        (
            [1] => name2
            [2] => address2
            [3] => town2
            [4] => state2
            [5] => zip2
            [6] => phone2
            [7] => website2
            [8] => other1
            [9] => other1
        )

    [24] => Array
        (
            [1] => name3
            [2] => address3
            [3] => town3
            [4] => state3
            [5] => zip3
            [6] => phone3
            [7] => website3
            [8] => other1
            [9] => other1
        )
}

Надеюсь, это поможет
