Php 将数据库日期转换为unix时间戳

我从数据库中得到一个数组，如下所示：

array
(
[section] => colours
[dd] => 1
[mm] => 3
[yy] => 13
[name] => red
)
array
(
[section] => colours
[dd] => 15
[mm] => 3
[yy] => 13
[name] => green
)
array
(
[section] => colours
[dd] => 15
[mm] => 3
[yy] => 13
[name] => blue
)

现在，我想将每个日期（dd/mm/yy）转换为unix时间戳，以便以后可以将其与当前时间戳进行比较

有什么建议吗？？提前感谢

您可以使用功能

strotime

，例如：

strtotime($data['dd'].'-'.$data['mm'].'-'.$data['yy']);

<?php

$dates = array(
    array(
        'section' => 'colours',
        'dd' => 1,
        'mm' => 3,
        'yy' => 13,
        'name' => 'red',
    ),
    array(
        'section' => 'colours',
        'dd' => 15,
        'mm' => 3,
        'yy' => 13,
        'name' => 'green',
    ),
    array(
        'section' => 'colours',
        'dd' => 15,
        'mm' => 3,
        'yy' => 13,
        'name' => 'blue',
    ),
);


for ($i = 0; $i < count($dates); $i++) {
    $dates[$i]['timestamp'] = strtotime('20' . $dates[$i]['yy'] . '-' . $dates[$i]['mm'] . '-' . $dates[$i]['dd']);
}

print_r($dates);
