问题描述
如果我有一个多维数组PHP中像这样...
[0] =＆GT;排列
????（
????????[URL] =＆GT; http://domain1.com
????????[域] =＆GT; domain1.com
????????[值] =＆GT;排列
????????????（
????????????????[CHARACTER_LENGTH] =＆GT; 25
????????????????[WORD_COUNT] =＆GT; 7
????????????）????）????[1] =＆GT;排列
????（
????????[URL] =＆GT; http://domain2.com
????????[域] =＆GT; domain2.com
????????[值] =＆GT;排列
????????????（
????????????????[CHARACTER_LENGTH] =＆GT;三十
????????????????[WORD_COUNT] =＆GT; 7????）
我怎样才能把它们合并产生....
[0] =＆GT;排列
????（
????????[URL] =＆GT; *可以是任何东西*
????????[域] =＆GT; *可以是任何东西*
????????[值] =＆GT;排列
????????????（
????????????????[CHARACTER_LENGTH] =＆GT; 55
????????????????[WORD_COUNT] =＆GT; 14
????????????）????）
解决方案
只是做一个简单的的foreach 上的所有项目和求和的值：
$值=阵列（
????CHARACTER_LENGTH'=＆GT; 0，
????WORD_COUNT'=＆GT; 0
）;
的foreach（$数组作为$项目）{
????$值['CHARACTER_LENGTH'] + = $项目['值'] ['CHARACTER_LENGTH'];
????$值['WORD_COUNT'] + = $项目['值'] ['WORD_COUNT'];
}
If I have a multi dimensional array in PHP like so...
[0] => Array
(
[url] => http://domain1.com
[domain] => domain1.com
[values] => Array
(
[character_length] => 25
[word_count] => 7
)
)
[1] => Array
(
[url] => http://domain2.com
[domain] => domain2.com
[values] => Array
(
[character_length] => 30
[word_count] => 7
)
How can I merge them to produce....
[0] => Array
(
[url] => *can be anything*
[domain] => *can be anything*
[values] => Array
(
[character_length] => 55
[word_count] => 14
)
)
解决方案
Just do a simple foreach on all items and sum the values:
$values = array(
'character_length' => 0,
'word_count' => 0
);
foreach ($array as $item) {
$values['character_length'] += $item['values']['character_length'];
$values['word_count'] += $item['values']['word_count'];
}
