Php 在数组中分解和存储值，忽略空值

我要分析以下示例记录：

@2013-01-19 02:45:00,1.32927,1.33029,1.32909,1.33018,464
@2013-01-19 03:00:00,1.33019,1.33142,1.33019,1.33081,637
@2013-01-19 03:15:00,1.33083,1.33129,1.33069,1.33095,425
@2013-01-19 03:30:00,1.33092,1.3317,1.33045,1.33144,500
@2013-01-19 03:45:00,1.33146,1.33211,1.33095,1.33196,480
@2013-01-19 04:00:00,1.33197,1.33291,1.33166,1.33264,593
@2013-01-19 04:15:00,1.33267,1.33308,1.33234,1.33238,366
@2013-01-19 04:30:00,1.33239,1.33278,1.33236,1.33263,335

使用此php代码，iam尝试将每一行存储在一个具有五个索引的数组中（该行用逗号分解）：

我不知道零（空数组）是从哪里来的

代码有问题吗？

感谢您的帮助。

删除第一个

@

而不是将其分解：

$lines[] = '2013-01-19 02:45:00,1.32927,1.33029,1.32909,1.33018,464';
    foreach($lines as $line){
        $data = explode('@', $line);
        foreach($data as $record){
            $val = explode(',',$record);
            echo '<pre>';
            print_r($val);
            echo '</pre>';
        }
    }

foreach（$line作为$line）{
//删除第一个字符
$record=substr（$line，1）；
$val=explode（“，”，$record）；
回声'；

在

@

上分解会在

$data

数组中产生空值-

删除$data=explode（'@'，$line）；如果不需要，或根据您的需要进行更改

$lines[]=“2013-01-19 02:45:00,1.32927,1.33029,1.32909,1.33018464”；
foreach（$line作为$line）{
$data=分解（'@'，$line）；
foreach（$数据作为$记录）{
$val=explode（“，”，$record）；
