Question

我有一个看起来像这样的大型多维数组（日期值是年 - 月 - 日）：

$current_branch = array(
            array('2014-05-26',100,17600,20600,3000,80,15000,18000, 2000),
            array('2014-05-27',100,17600,20600,3000,80,15000,18000, 2000),
            array('2014-05-28',100,17600,20600,3000,80,15000,18000, 2000),
            array('2014-05-29',100,16600,20600,3000,80,15000,18000, 2000),

如您所见，某些日期等缺失。现在，数组索引已经为我正在做的不可思议的数字（使用预定义的soap服务器的结果），但这很好，因为心理记录可以由值组成，并且它们是是;销售日期，现金销售数量，当天现金净额等......

我想知道的是我如何操纵那个庞大的数组以获取其中月份的总净值（例如，可以说第3个值是那天的净值）和输出它们是一个看起来像这样的数组：

$data = array(
  array('jan', $jan_month_net), array('feb', $feb_month_net), 
  array('mar', $mar_month_net), array('apr', ...), 
  array('may', ...), array('jun', ...), 
  array('jul', ...), array('aug', ...), 
  array('sept', ...), array('oct', ...), 
  array('nov', ...),  array('dec', ...)
);

我尝试过使用foreach：

$this_year_value = 2015;
$i=01;
foreach ($current_branch as $key => $value) {
    $i_padded = sprintf("%02d", $i); // so 01, 02, 03, etc
    $month_comparison = $this_year_value."-".$i_padded;
    $cut_soap_date = substr($value[0],0,7); // try to get 2015-MONTH
    if ($cut_soap_date == $month_comparison) { 
        $year_chart_data =  array($i_padded, $value[2]);
    }
$i++; 
}

这段代码有一个根本的缺陷，因为$ i会在每个foreach处递增，实际上从未提供与当前foreach月指针的正确比较。这是我缺乏想法的地方，如果有任何想法可以提供，那就太棒了。

Answer 1

如果日期不匹配，只增加$ i怎么样

if ($cut_soap_date == $month_comparison) { 
    $year_chart_data =  array($i_padded, $value[2]);
} else {
    $i++; 
}

Answer 2

$this_year_value = 2015;

// Make array before
$data = array(
  array('jan', 0), array('feb', 0), 
  array('mar', 0), array('apr', 0), 
  array('may', 0), array('jun', 0), 
  array('jul', 0), array('aug', 0), 
  array('sept', 0), array('oct', 0), 
  array('nov', 0),  array('dec', 0)
);

// fill array 
foreach ($current_branch as $key => $value) {
    // take second part of date
    $month_comparison = explode('-', $value[0])[1];
    $cut_soap_date = substr($value[0],0,7); // try to get 2015-MONTH
    if ($cut_soap_date == $this_year_value."-".$month_comparison) { 
        // write to result array
        $data[$month_comparison-1][1] += $value[2];
    }
}

var_export($data);
