如何將數組導出到csv

Question

["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", "Boxname:HH, X1:53.3, X2:106.6, Y1:33.300000000000004,Y2:59.947215189873425, PID:33, GENDER:MALE, Age:58,Bp_Systolic:130,Bp_Diastolic:70", "Boxname:HH, X1:53.3, X2:106.6, Y1:33.300000000000004,Y2:59.947215189873425, PID:48, GENDER:FEMALE, Age:62,Bp_Systolic:132,Bp_Diastolic:80", "Boxname:HH, X1:53.3, X2:106.6, Y1:33.300000000000004,Y2:59.947215189873425, PID:50, GENDER:MALE, Age:60,Bp_Systolic:120,Bp_Diastolic:70", "Boxname:MH, X1:53.3, X2:106.6, Y1:33.300000000000004,Y2:59.947215189873425, PID:51, GENDER:MALE, Age:63,Bp_Systolic:118,Bp_Diastolic:62"]

我想將此數組轉換為 csv 導出文件。 我試過這樣的代碼。

<?php
header('Content-Type: text/csv; charset=utf-8');
header('Content-Disposition: attachment; filename=data.csv');

// create a file pointer connected to the output stream
$output = fopen('php://output', 'w');

// output the column headings
fputcsv($output, array('Column 1', 'Column 2', 'Column 3'));

$list=$name;
foreach ($list as $line)
  {
fputcsv($output, $line);
  }

?>

但我無法獲取數據。 任何機構都可以幫助我。 我嘗試了很多方法。 我認為我的數組格式有問題。 任何人都可以從中建議數組格式以使導出變得容易。

Answer 1

您將一串串聯值作為行傳遞給fputcsv() ，其中每列都有一個數組元素。 您的數據應拆分為每行的列值數組，即：

$list = Array(
    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"),
    Array("Boxname:HH", "X1:53.3", ..)
    //etc
)

更改此數組是您將如何解決此問題。 如果您無法更改數組的創建方式，您始終可以使用array_map()重新映射它以使其具有fputcsv()期望的格式：

$list = ["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", "Boxname:HH, X1:53.3, X2:106.6, Y1:33.300000000000004,Y2:59.947215189873425, PID:33, GENDER:MALE, Age:58,Bp_Systolic:130,Bp_Diastolic:70", "Boxname:HH, X1:53.3, X2:106.6, Y1:33.300000000000004,Y2:59.947215189873425, PID:48, GENDER:FEMALE, Age:62,Bp_Systolic:132,Bp_Diastolic:80", "Boxname:HH, X1:53.3, X2:106.6, Y1:33.300000000000004,Y2:59.947215189873425, PID:50, GENDER:MALE, Age:60,Bp_Systolic:120,Bp_Diastolic:70", "Boxname:MH, X1:53.3, X2:106.6, Y1:33.300000000000004,Y2:59.947215189873425, PID:51, GENDER:MALE, Age:63,Bp_Systolic:118,Bp_Diastolic:62"];

$list = array_map(function($i){
    return array_map("trim", // Trim the values
        explode(",", $i) // Explode each row into an array of column values
    );
}, $list);

header('Content-Type: text/csv; charset=utf-8');
header('Content-Disposition: attachment; filename=data.csv');

$output = fopen('php://output', 'w');

fputcsv($output, array('Column 1', 'Column 2', 'Column 3'));

foreach ($list as $line) {
    fputcsv($output, $line);
}

Answer 2

這是一個工作解決方案的示例，也許您可​​以將其用作基礎：

$maxSize = count($commentArray);

    for ($c=0; $c < $maxSize; $c++) {
        $toCSV .= $nameArray[$c] . ";" . $amountArray[$c] . ";" . $dateArray[$c] . ";" . $commentArray[$c] . ";" . $bankaccount[$c] . "\n";
    }

file_put_contents($file, $toCSV);       

它遍歷數組的所有元素，用;分隔值; s，當到達最后一個元素時，它會放置一個新的行分隔符。

將其連接為一個整體后，file_put_contents 將創建一個 CSV 文件。
