将 csv 内容放入多维数组

Question

我有一个包含以下行的 csv 文件

enter code here

23,cars,43 063
23,cars,17 306
23,houses,13 300
23,garage,13 094
23,hotels,10 025
22,cars,75 675
22,cars,40 403
22,houses,32 243
22,garage,30 649
22,hotels,29 734
21,hotels,29 734
22,hotels,29 734

这是我用来解析 csv 文件的代码

     function readCSV($csvFile){
$file_handle = fopen($csvFile, 'r');
while (!feof($file_handle) ) {
    $line_of_text[] = fgetcsv($file_handle, 1024);
}



fclose($file_handle);
return $line_of_text;




    }

当我显示 $line_of_text 的内容时；数组，这是我得到的

      Array
       (
      [0] => Array
      (
        [0] => 23
        [1] => cars
        [2] => 43 063
      )

[1] => Array
    (
        [0] => 23
        [1] => cars
        [2] => 17 306
    )

[2] => Array
    (
        [0] => 23
        [1] => houses
        [2] => 13 300
    )

.....

但这不是我想要的，我希望我的数组以这种方式显示

 array (
 23 => array(
    'cars' => 43063,
    'houses' => 17306,
    'shops' => 13300,
    'garages' => 13094,
    'hotels' => 10025
 ),
 22 => array(
    'cars' => 75675,
    'houses' => 40403,
    'shops' => 32243,
    'garages' => 30649,
    'hotels' => 29734,
    'test' => 29734
     )
    );

我如何做到这一点？你能帮帮我吗？

//更新新我的数组的内容

 Array
 (
 [0] => Array
    (
        [0] => cars
        [1] => 00
        [2] => 0
    )

[1] => Array
    (
        [0] => cars
        [1] => 01
        [2] => 0
    )

[2] => Array
    (
        [0] => cars
        [1] => 02
        [2] => 0
    )


[3] => Array
    (
        [0] => cars
        [1] => 11
        [2] => 0
    )

[4] => Array
    (
        [0] => cars
        [1] => 23
        [2] => 4425
    )

[5] => Array
    (
        [0] => houses
        [1] => 00
        [2] => 198
    )

[6] => Array
    (
        [0] => houses
        [1] => 01
        [2] => 742
    )

[7] => Array
    (
        [0] => houses
        [1] => 02
        [2] => 168
    )
)

Answer 1

$fp = fopen($csvFile, 'r');
$master = array();
while( $line = fgetcsv( $fp ) ) {
    // 23,cars,43 063
    if( !isset( $master[$line[0]] ) )
        $master[$line[0]] = array();

    if( !isset( $master[$line[0]][$line[1]] ) )
        $master[$line[0]][$line[1]] = 0;

    $n = filter_var($line[2], FILTER_SANITIZE_NUMBER_INT);
    $master[$line[0]][$line[1]] += $n;
}

var_dump( $master );

没有测试，但应该可以。如果您有任何问题，请告诉我。

Answer 2

试试这样的！

$line_of_text=array();
while (!feof($file_handle) ) {
    $line = fgetcsv($file_handle, 1024);

    if(isset($line_of_text[ $line[0] ][ $line[1] ] ))
        $line_of_text[$line[0]][$line[1]]+=str_replace(" ", "", $line[2]);
    else
        $line_of_text[$line[0]][$line[1]]=str_replace(" ", "", $line[2]);

}
