csv to php - 根據第一列的值選擇特定的行

Question

我使用外部.csv文件來推斷php中的一些值並進行計算。我的.csv以下列方式結構化（這是一個非常簡單的例子，我的CSV通常有50/60行每個人用不同的名稱）：

銷售，10,24,56
收入，14， 71,105

我想使用PHP指令來選擇只有名爲「收入」或只有名爲「銷售」的行。到目前爲止，我已經使用了「for」循環，但它僅基於i ++變量。

$csv = str_getcsv(file_get_contents('csv/sample.csv'));  

for ($i = 12, $k=$i+11; $i < $k; $i++) { 
      echo '<td>'; 
      echo number_format($csv[$i],0,'.',','); 
      echo '</td>'; 
     } 
echo '</tr>'; 

如果「銷售」和「收入」有不同的位置，我無法調用正確的值。

UPDATE：

這是的print_r（$ CSV）

Answer 1

首先使用preg_grep & file與str_getcsv解決您的問題。

首先$file = file('csv/sample.csv');

然後$revenues = preg_grep ('/^Revenues/i', $file);

然後

for ($revenues as $revenue) 
{ 
    $revenue = str_getcsv($revenue); 
    echo $revenue[0] . $revenue[1] . $revenue[2] . $revenue[3];//Revenue key 0,1,2,3 
} 

然後$sales = preg_grep ('/^Sales/i', $file);

然後

for ($sales as $sale) 
{ 
    $sale = str_getcsv($sale); 
    echo $sale[0] . $sale[1] . $sale[2] . $sale[3];//Sale key 0,1,2,3 
} 

Answer 2

您可以將csv讀取到指定的關鍵數組中，然後通過名稱引用相關的行條目。

$csv = array(); 
$file = new SplFileObject("csv/sample.csv"); 
$file->setFlags(SplFileObject::READ_CSV); 
foreach($file as $index => $row) { 
    $csv[ strtolower($row[0])]=array_splice($row, 1, count($row)); 
} 

echo '<pre>',print_r($csv['sales'],true),'</pre>'; 

Answer 3

試試這個

$sales = []; 
$revenues = []; 
foreach($csv as $key => $val) 
{ 
    $sales[] = $val['Sales']; 
    $revenues[] $val['Revenue']; 
} 
print_r($sales); 
print_r($revenues); 

如果你想獲得的所有數據的：

$data = []; 
foreach($csv as $key => $val) 
{ 
$data[] = ['Sales' => $val['Sales'], 'Revenue' => $val['Revenue'], ......]; // so on and so forth. 
} 
print_r($data);
