我有一个日期在10:30到11点之间的数组。这些项目按时间顺序列出。
我正在寻找一个PHP解决方案来重新排列数组的结构或智能循环，这样我就可以按照自己的意愿组织日期。
我需要回应的是： （旧尝试，请忽略此示例。只需将其保留在已提供的解决方案中。请参阅下面的更新。）
'1', '1, 10, 2017', '1, 11, 2017'
'2', '2, 10, 2017', '2, 11, 2017',
...
'30', '30, 10, 2017', '30, 11, 2017',
'31', '31, 10, 2017', ''
请注意，11月（11）只有30天，所以没有第31个条目。
所以我需要一个遍历数组的循环，并以相同的开始日回显所有日期，然后执行<br>或类似的操作。它总是应该在第31位结束，有没有数据。
更新
我的输出需要略有不同：
['1', '1, 10, 2017', '1, 11, 2017'],
['2', '2, 10, 2017', '2, 11, 2017'],
...
['30', '30, 10, 2017', '30, 11, 2017'],
['31', '31, 10, 2017', '0, 0, 0']
主要变化是：
'0, 0, 0'而不是空字符串。背景是我有一个必然需要任何值的函数，可能是0。
我尝试了不同的东西（将日期，月份和年份分开来分离数组/使用for-loops /使用foreach-loops）但没有真正起作用。我的主要问题似乎是每个月都有不同的天数。
您是否有任何建议如何使其正常工作？ 尝试重组阵列可能会更好吗？还是有其他解决方案？
代码应该适用于不同的日期范围（不仅仅是我上面提到的那些）。
这是我的阵列：

我建议甚至不做那样的事。日期和时间不是你想要手动处理的东西，因为它们比它们看起来要复杂得多。
<?php
$period = new DatePeriod(
new DateTime('2017-01-01'), // start
new DateInterval('P1M'), // interval of 1 month
new DateTime('2018-01-01') // end
);
foreach( $period as $date ) {
printf("%s\n", $date->format('Y-m-d'));
}
输出：
2017-01-01
2017-02-01
2017-03-01
2017-04-01
2017-05-01
2017-06-01
2017-07-01
2017-08-01
2017-09-01
2017-10-01
2017-11-01
2017-12-01

正如经验法则所示：如果您发现自己手动定义了大量重复的数组，那么您应该退后一步并重新检查您的方法。

我全心全意地同意@Sammitch对此的看法。如果必须使用此数组，则可以遍历数组并使用strtotime在Unix时间内转换条目：
foreach($date_array as $key => $value) {
$value = explode(",",$value);
$value = trim($value[2])."-".trim($value[1])."-".trim($value[0]);
$value = strtotime($value);
$date_array[$key] = $value;
}
如果您想要按原样处理数组，可以使您接近所需内容：
<?php
$date_array = array(
0 => "1, 10, 2017",
1 => "2, 10, 2017",
2 => "3, 10, 2017",
3 => "4, 10, 2017",
4 => "5, 10, 2017",
5 => "6, 10, 2017",
6 => "7, 10, 2017",
7 => "8, 10, 2017",
8 => "9, 10, 2017",
9 => "10, 10, 2017",

看来您所需的结果是一种伪数组字符串。如果您打算将其用作数组或json，我可以优化此代码以更好地满足您的最终要求。
代码展示3个不同的起点：（Demo）
function buildPseudoArray($month1,$year1){ // default dates in params: $month1=date('m'),$year1=date('Y') causes Fatal error
echo "Result for $month1-$year1:\n";
$m1_last=date('t',strtotime("$year1-$month1"));
if($month1==12){
$year2=$year1+1;
$month2=1;
}else{
$year2=$year1;
$month2=$month1+1;
}
$m2_last=date('t',strtotime("$year2-$month2"));
$result='';
for($i=1,$stop=31; $i<=$stop; ++$i){
$result.="['$i', ";
$result.=$i<=$m1_last ? "'$i, $month1, $year1', " : "'0, 0, 0', "; // conditionally fill missing dates
$result.=$i<=$m2_last ? "'$i, $month2, $year2'" : "'0, 0, 0'"; // conditionally fill missing dates
$result.=']'.($i<$stop ? ',' : '')."\n"; // conditionally add comma to end of row
}
return $result;
}
echo buildPseudoArray(1,2017); // shows 0, 0, 0 in first column
echo "\n---------------------\n";
echo buildPseudoArray('2',2017); // shows 0, 0, 0 in second column
echo "\n---------------------\n";
echo buildPseudoArray(12,2017); // shows incrementation into next year
