May this will help. http://www.php.net/manual/de/function.fgetcsv.phpJust grab the position of the row for the column you want to have.
愿这会有所帮助。 http://www.php.net/manual/de/function.fgetcsv.php只需抓住您想要的列的行位置。

$csv = array_map("str_getcsv", file("data.csv", "r"));
$header = array_shift($csv);
// Seperate the header from data
$col = array_search("Value", $header);
foreach ($csv as $row) {
$array[] = $row[$col];
}

$arr=array();
$row = -1;
if (($handle = fopen("test.csv", "r")) !== FALSE) {
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
$num = count($data);
$row++;
for ($c = 0; $c < $num; $c++) {
$arr[$row][$c]= $data[$c];
}
}
fclose($handle);
}

You should give fgetcsvmethod a try. It lets you read a file line by line and returns associative array. This function is specially for reading from CSV files.
你应该fgetcsv试试方法。它允许您逐行读取文件并返回关联数组。此功能专门用于读取 CSV 文件。
In any case you will have to read each line even if you will have to process just a column.
在任何情况下，即使您只需要处理一列，您也必须阅读每一行。
