递归地应用array_map(array_walk_recursive?) [英] Applying array_map recursively (array_walk_recursive?)
问题描述
我有一个关联数组，该数组是我通过使用以下代码的ODBC查询创建的:
I have an associative array that is I am creating from an ODBC query with the following code:
while ($row=odbc_fetch_array($oexec)) {
if(empty($group[$row['gmm']])) {
$group[$row['gmm']] = array();
}
if(empty($group[$row['gmm']][$row['acctg_dept_nbr'] . " - " . $row['acctg_dept_desc']])) {
$group[$row['gmm']][$row['acctg_dept_nbr'] . " - " . $row['acctg_dept_desc']] = array();
}
if(empty($group[$row['gmm']][$row['acctg_dept_nbr'] . " - " . $row['acctg_dept_desc']][$row['dept_catg_grp_desc']])) {
$group[$row['gmm']][$row['acctg_dept_nbr'] . " - " . $row['acctg_dept_desc']][$row['dept_catg_grp_desc']] = array();
}
if(empty($group[$row['gmm']][$row['acctg_dept_nbr'] . " - " . $row['acctg_dept_desc']][$row['dept_catg_grp_desc']][$row['dept_category_desc']])) {
$group[$row['gmm']][$row['acctg_dept_nbr'] . " - " . $row['acctg_dept_desc']][$row['dept_catg_grp_desc']][$row['dept_category_desc']] = array();
}
if(empty($group[$row['gmm']][$row['acctg_dept_nbr'] . " - " . $row['acctg_dept_desc']][$row['dept_catg_grp_desc']][$row['dept_category_desc']][$row['dept_subcatg_desc']])) {
$group[$row['gmm']][$row['acctg_dept_nbr'] . " - " . $row['acctg_dept_desc']][$row['dept_catg_grp_desc']][$row['dept_category_desc']][$row['dept_subcatg_desc']] = array();
}
$group[$row['gmm']][$row['acctg_dept_nbr'] . " - " . $row['acctg_dept_desc']][$row['dept_catg_grp_desc']][$row['dept_category_desc']][$row['dept_subcatg_desc']]['total_ty_yest_sales'] = $row['total_ty_yest_sales'];
$group[$row['gmm']][$row['acctg_dept_nbr'] . " - " . $row['acctg_dept_desc']][$row['dept_catg_grp_desc']][$row['dept_category_desc']][$row['dept_subcatg_desc']]['total_wo_dotcom_ty_yest_sales'] = $row['total_wo_dotcom_ty_yest_sales'];
$group[$row['gmm']][$row['acctg_dept_nbr'] . " - " . $row['acctg_dept_desc']][$row['dept_catg_grp_desc']][$row['dept_category_desc']][$row['dept_subcatg_desc']]['east_ty_yest_sales'] = $row['east_ty_yest_sales'];
$group[$row['gmm']][$row['acctg_dept_nbr'] . " - " . $row['acctg_dept_desc']][$row['dept_catg_grp_desc']][$row['dept_category_desc']][$row['dept_subcatg_desc']]['central_ty_yest_sales'] = $row['central_ty_yest_sales'];
$group[$row['gmm']][$row['acctg_dept_nbr'] . " - " . $row['acctg_dept_desc']][$row['dept_catg_grp_desc']][$row['dept_category_desc']][$row['dept_subcatg_desc']]['west_ty_yest_sales'] = $row['west_ty_yest_sales'];
$group[$row['gmm']][$row['acctg_dept_nbr'] . " - " . $row['acctg_dept_desc']][$row['dept_catg_grp_desc']][$row['dept_category_desc']][$row['dept_subcatg_desc']]['dotcom_ty_yest_sales'] = $row['dotcom_ty_yest_sales'];
}
这给了我一个数组，其中:
This gives me an array where:
$myArray = Array(GMM => Array(acctg_dept_nbr => Array(dept_category_desc => Array(dept_subcatg_desc => Array(value1,value2,value3)))))
我想对每个级别的值求和.因此，对于每个acctg_dept_nbr [dept_category_desc] [dept_subcatg_desc]，我想对value1，value2，value3求和.对于GMM级别相同，直到dept_subcatg_desc级别.总结dept_subcatg_desc级别不是问题.我四处摸索，发现了如何对dept_category_desc级别求和，但是在递归地应用该方法时遇到了麻烦.
I want to sum the values at every level. So for every acctg_dept_nbr[dept_category_desc][dept_subcatg_desc] I want to sum value1,value2,value3. Same for the GMM level and down to the dept_subcatg_desc level. Summing the dept_subcatg_desc level wasn't a problem. I dug around and found how to sum the dept_category_desc level, but am having trouble applying that method recursively.
以下是将值放入表中的代码:
Here is the code that puts the values into a table:
foreach($group as $gmm => $acctg_dept_nbrs) {
echo "<tr class=\"header\">
<td>" . $gmm . "</td>\n";
foreach ($acctg_dept_nbrs as $acctg_dept_nbr => $dept_catg_grp_descs) {
echo "<tr class=\"header\">\n
<td style=\"padding-left: 1em;\">" . $acctg_dept_nbr . "</td>\n";
foreach($dept_catg_grp_descs as $dept_catg_grp_desc => $dept_category_descs) {
echo "<tr class=\"header\">\n
<td style=\"padding-left: 2em;\">" . $dept_catg_grp_desc . "</td>\n";
//echo "<td>" . array_sum(array_walk_recursive($dept_category_descs,function($item) {return $item['total_ty_yest_sales'];})) . "</td>";
foreach($dept_category_descs as $dept_category_desc => $dept_subcatg_descs) {
echo "<tr class=\"header\">\n
<td style=\"padding-left: 3em;\">" . $dept_category_desc . "</td>\n";
echo "<td>" . array_sum(array_map(function($item) {return $item['total_ty_yest_sales'];},$dept_subcatg_descs)) . "</td>";
echo "<td>" . array_sum(array_map(function($item) {return $item['east_ty_yest_sales'];},$dept_subcatg_descs)) . "</td>";
echo "<td>" . array_sum(array_map(function($item) {return $item['central_ty_yest_sales'];},$dept_subcatg_descs)) . "</td>";
echo "<td>" . array_sum(array_map(function($item) {return $item['west_ty_yest_sales'];},$dept_subcatg_descs)) . "</td>";
foreach($dept_subcatg_descs as $dept_subcatg_desc => $values) {
echo "<tr>\n
<td style=\"padding-left: 4em;\">" . $dept_subcatg_desc . "</td>\n";
$sum = $values['total_ty_yest_sales'];
echo "<td>".$sum."</td>";
$sum = $values['east_ty_yest_sales'];
echo "<td>".$sum."</td>";
$sum = $values['central_ty_yest_sales'];
echo "<td>".$sum."</td>";
$sum = $values['west_ty_yest_sales'];
echo "<td>".$sum."</td>";
}
}
}
}
}
注释掉的行现在对我来说是个问题.这个:
The commented out line is the problem for me now. This:
array_sum(array_map(function($item) {return $item['west_ty_yest_sales'];},$dept_subcatg_descs))
在该级别上可以正常工作，但在较高级别上则不能.我也曾尝试对该功能进行调整，但无济于事:
works fine at that level, but not at the higher levels. I have also tried to tweak this function to no avail:
function array_map_recursive($callback, $array) {
foreach ($array as $key => $value) {
if (is_array($array[$key])) {
$array[$key] = array_map_recursive($callback, $array[$key]);
}
else {
$array[$key] = call_user_func($callback, $array[$key]);
}
}
return $array;
}
我该如何进行这项工作，以便无论其级别如何，都将对其进行挖掘并求和该数组那部分的值?
How can I make this work so that regardless of level it will dig down and sum the values for that portion of the array?
推荐答案
function array_map_recursive($callback, $array)
{
$func = function ($item) use (&$func, &$callback) {
return is_array($item) ? array_map($func, $item) : call_user_func($callback, $item);
};
return array_map($func, $array);
}
