【问题描述】：

我从 csv 文件中读取了以下数组：

Array
(
[0] => Array
    (
        [0] => book1
        [1] => description1
        [2] => category1
        [3] => code1
        [4] => editor1
        [5] => 0
        [6] => eur
        [7] => out of stoc
    )

[1] => Array
    (
        [0] => book2
        [1] => description2
        [2] => category2
        [3] => code2
        [4] => editor2
        [5] => 0
        [6] => curr2
        [7] => out of stoc
    )

[2] => Array
    (
        [0] => book3
        [1] => description3
        [2] => category3
        [3] => code3
        [4] => editor3
        [5] => 0
        [6] => curr3
        [7] => out of stoc
    )

)

代码：

function read_CSV_raza($rzs_csv) {
$file_handle = fopen($rzs_csv, 'r');
while (!feof($file_handle)) {
$line_of_text[] = fgetcsv($file_handle, 1024, ';');
}
fclose($file_handle);
return $line_of_text;
}

$rzs_csv = 'rzs.csv';
$csv = read_CSV_raza($rzs_csv);

我想添加另一个数组（标题），以便将此介绍写入另一个 csv 文件。前：

Array
(
[0] => Array
(
    [0] => h1
    [1] => h2
    [2] => h3
    [3] => h4
    [4] => h5
    [5] => h6
    [6] => h7
    [7] => h8
)
[1] => Array
(
    [0] => book1
    [1] => description1
    [2] => category1
    [3] => code1
    [4] => editor1
    [5] => 0
    [6] => eur
    [7] => out of stoc
)

[2] => Array
(
    [0] => book2
    [1] => description2
    [2] => category2
    [3] => code2
    [4] => editor2
    [5] => 0
    [6] => curr2
    [7] => out of stoc
)

[3] => Array
(
    [0] => book3
    [1] => description3
    [2] => category3
    [3] => code3
    [4] => editor3
    [5] => 0
    [6] => curr3
    [7] => out of stoc
)

)

我尝试使用 array_merge(); array_unshift();但无济于事，我没有得到我需要的结果。

在新的 CSV 中写入数组的代码是：

$fp = fopen('rezultate.csv', 'w') or die("Can't open rezultate.csv");
foreach ($csv as $items) {
fputcsv($fp, $items, ';', '"');
}
fclose($fp) or die("Can't close rezultate.csv");

由于我不是程序员，因此我们将不胜感激。

【问题讨论】：

只需在 foreach ($csv as $items) 循环之前立即执行 fputcsv($fp, $headers, ';', '"');...。它比 array_unshift() 更有效
刚刚做了，但现在它只写入标题而不是数组
$fp = fopen('rezultate.csv', 'w') or die("Can't open rezultate.csv"); fputcsv($fp, $headers, ';', '"'); foreach ($csv as $items) { fputcsv($fp, $items, ';', '"'); } fclose($fp) or die("Can't close rezultate.csv");
非常感谢您像梦一样工作！

【解决方案1】：

array_unshift 为我工作：

$add = array (
    0 => "h1",
    1 => "h2",
    2 => "h3",
    3 => "h4",
    4 => "h5",
    5 => "h6",
    6 => "h7",
    7 => "h8"
);
array_unshift($myarray, $add);

还有

array_unshift($myarray, array(0 => "h1", 1 => "h2", 2 => "h3", 3 => "h4", 4 => "h5", 5 => "h6", 6 => "h7", 7 => "h8"));
