PHP CSV字符串到数组

Question

我正在尝试将CS​​V字符串解析为PHP中的数组.CSV字符串具有以下属性:

Delimiter: ,
Enclosure: "
New line: \r\n

示例内容:

"12345","Computers","Acer","4","Varta","5.93","1","0.04","27-05-2013"
"12346","Computers","Acer","5","Decra","5.94","1","0.04","27-05-2013"

当我尝试解析它时:

$url = "http://www.url-to-feed.com";
$csv = file_get_contents($url);
$data = str_getcsv($csv);
var_dump($data);

最后一个元素和一个元素串在一个字符串中:

[0]=> string(5) "12345"
...
[7]=> string(4) "0.04"
[8]=> string(19) "27-05-2013
"12346""

我怎样才能解决这个问题？任何帮助,将不胜感激.

做这个:

$csvData = file_get_contents($fileName);
$lines = explode(PHP_EOL, $csvData);
$array = array();
foreach ($lines as $line) {
    $array[] = str_getcsv($line);
}
print_r($array);

它会给你一个像这样的输出:

Array
(
    [0] => Array
        (
            [0] => 12345
            [1] => Computers
            [2] => Acer
            [3] => 4
            [4] => Varta
            [5] => 5.93
            [6] => 1
            [7] => 0.04
            [8] => 27-05-2013
        )

    [1] => Array
        (
            [0] => 12346
            [1] => Computers
            [2] => Acer
            [3] => 5
            [4] => Decra
            [5] => 5.94
            [6] => 1
            [7] => 0.04
            [8] => 27-05-2013
        )

)

我希望这可以提供一些帮助.

方便的oneliner:

$csv = array_map('str_getcsv', file('data.csv'));

Answer 3

你应该使用fgetcsv. 由于您无法将文件作为流导入,因为csv是变量,因此您应该使用php://temp或php://memory首先将字符串伪装成文件:

$fp = fopen("php://temp", 'r+');
fputs($fp, $csvText);
rewind($fp);

然后使用fgetcsv就没问题了:

$csv = [];
while ( ($data = fgetcsv($fp) ) !== FALSE ) {
    $csv[] = $data;
}

$data 将是一个单个csv行的数组(可能包括换行符或逗号等),因为它应该是.

我使用以下函数将csv字符串解析为关联数组

public function csvToArray($file) {
    $rows = array();
    $headers = array();
    if (file_exists($file) && is_readable($file)) {
        $handle = fopen($file, 'r');
        while (!feof($handle)) {
            $row = fgetcsv($handle, 10240, ',', '"');
            if (empty($headers))
                $headers = $row;
            else if (is_array($row)) {
                array_splice($row, count($headers));
                $rows[] = array_combine($headers, $row);
            }
        }
        fclose($handle);
    } else {
        throw new Exception($file . ' doesn`t exist or is not readable.');
    }
    return $rows;
}

如果您的csv文件名是mycsv.csv,那么您将此函数称为:

$dataArray = csvToArray(mycsv.csv);
