Question

如果缺少某些数据，我会检查csv文件，

数组的标头包含需要匹配的字符串。

首先我需要检查第一个数组是否包含日期，时间，L1，L2，L3

从第二个数组开始，它应该始终检查日期和时间格式。

以下是我试过的代码

$file_handle = fopen($csvFile, 'r');
    $current_line="";
    echo "<pre>";
    $i=0;
    while (!feof($file_handle) ) {
        $current_line = fgetcsv($file_handle, 1024);

        print_r($current_line);
        if(@in_array('', $current_line) )
        {
            throw new Exception('Some data is missing');
        }
        else {
            $line_of_text[] = $current_line;
            //print_r($line_of_text);
        }
        $i++;
    }

    fclose($file_handle);

打印$ current_line给我这个

 Array
(
    [0] => Date
    [1] => Time
    [2] => L1
    [3] => L2
    [4] => L3
)
Array
(
    [0] => 10/31/2013
    [1] => 13:53:35
    [2] => 39.8
    [3] => 36.2
    [4] => 39.6
)

Array
(
    [0] => 10/31/2013
    [1] => 13:53:40
    [2] => 39.8
    [3] => 36.6
    [4] => 39.7
)

试试这个：

$file_handle = fopen($csvFile, 'r');
$a_cols_sample = array('Date', 'time', 'L1', 'L2', 'L3');
$a_cols = fgetcsv($file_handle, 1024);
if (!($a_cols && count($a_cols) == 5 && $a_cols === $a_cols_sample)) return;
$result = array();
while (($a_vals = fgetcsv($file_handle, 1024)) !== false) {
    if (count($a_vals) != 5) continue;
    list($date, $time, , , ) = $a_vals;
    if (date_create_from_format('d/m/Y', $date) === false) continue;
    if (date_create_from_format('h:i:s', $time) === false) continue;
    $result[] = $a_vals;
}
print_r($result);
fclose($file_handle);

验证来自fgetcsv的数组值
