Question

在一个日志文件中，我想知道用户登录失败的次数和日期详细信息我有这个代码，但它无法正常工作。

这是一个代码

$file = new SplFileObject("failed.log", "r");

while(!$file->eof()) 
    {   
      $data[] =  current (($file->fgetcsv("|"))) . next (($file->fgetcsv("|")));            
    }

$abc = implode(",", $data);
echo $abc;  

$br = "\n";

在这段代码中我得到了这样的

John26:Dec:2017:16:15:27,Abc29:Dec:2017:09:39:45,Bhumi29/Dec/2017 14:15:41,Abc

它不正确，它读取第一行名称和第二行日期我不会在我的代码中出错。

这是我的日志失败详情

正如评论中所建议的那样，您应该重新考虑将失败的登录保存到文本日志，特别是如果您打算将其作为例行操作。随着文件的增长，它将变得占用大量内存：

# Saves contents of file into array by end of lines
$explode = file("failed.log",FILE_SKIP_EMPTY_LINES);
# Loop rows
foreach($explode as $row) {
    # Explode the | character
    $exp    =   explode('|',$row);
    # Save the user to the an array
    $new[$exp[0]]['dates'][]    =   $exp[1];
    # Count how many times tried
    if(!isset($new[$exp[0]]['count']))
        $new[$exp[0]]['count']  =   1;
    else
        $new[$exp[0]]['count']  +=  1;
}

print_r($new);

应该给你：

Array
(
    [John] => Array
        (
            [dates] => Array
                (
                    [0] => 26:Dec:2017:16:09:45
                )

            [count] => 1
        )

    [cena] => Array
        (
            [dates] => Array
                (
                    [0] => 26:Dec:2017:16:15:27
                )

            [count] => 1
        )

    [Abc] => Array
        (
            [dates] => Array
                (
                    [0] => 27:Dec:2017:09:25:25
                    [1] => 04/Jan/2018 15:54:35
                )

            [count] => 2
        )

    [Bhumi] => Array
        (
            [dates] => Array
                (
                    [0] => 29:Dec:2017:09:39:45
                    [1] => 29:Dec:2017:10:19:28
                )

            [count] => 2
        )

    [Avccc] => Array
        (
            [dates] => Array
                (
                    [0] => 29/Dec/2017 14:15:41
                )

            [count] => 1
        )
)

使用print_r()查看如何访问数组键/值。
