我有一個(gè)多維數(shù)組搜索我的數(shù)組看起來像這樣Array( [0] => Array ( [id] => 1 [location] => 3 [location_fees] => 3 [gross_percentage] => 25 [transaction_percentage] => 0 [user_name] => admin [user_id] => 1 [gross] => yes [transaction] => no ) [1] => Array ( [id] => 2 [location] => 5 [location_fees] => 5 [gross_percentage] => 0 [transaction_percentage] => 24 [user_name] => admin [user_id] => 1 [gross] => no [transaction] => yes ) [2] => Array ( [id] => 3 [location] => 2 [location_fees] => 5 [gross_percentage] => 10 [transaction_percentage] => 0 [user_name] => admin [user_id] => 1 [gross] => yes [transaction] => no ))我使用下面的php，我知道它可能可以做得更干凈或更少的代碼，所以如果你有任何想法如何獲得相同的結(jié)果，我絕對(duì)會(huì)學(xué)習(xí)，我洗耳恭聽！這是我使用的 PHP： $key = false; $search = ['gross' => 'yes']; foreach ($results as $k => $v) { if ($v['gross'] == $search['gross'] ) { $key = $k; $location_fees = array_search('yes', array_column($results, 'gross','location_fees')); echo "The location fees: ". $location_fees ." % <br><br>"; $gross_percentage = array_search('yes', array_column($results, 'gross', 'gross_percentage')); echo "The gross_percentage is: ".$gross_percentage ."% <br><br>"; } } }它拒絕顯示鍵 #1 的位置費(fèi)用現(xiàn)在奇怪的是，如果我將地點(diǎn)費(fèi)用更改為 3，它就會(huì)顯示出來。但它不會(huì)帶有數(shù)字“5”，這也是位置#這與數(shù)字“5”沖突是否有原因？注意鍵“0”具有位置“3”和位置費(fèi)用“3”，并且它不會(huì)引起任何問題。我已經(jīng)在這個(gè)問題上堅(jiān)持了幾個(gè)小時(shí)了，它適用于鍵#0和#2，沒有任何問題。有任何想法嗎？

您遇到此問題的原因是您致電array_column：
array_column($results, 'gross','location_fees')
這會(huì)導(dǎo)致gross值被$results重新索引location_fees，對(duì)于您的數(shù)據(jù)來說，這會(huì)導(dǎo)致類似的結(jié)果
[3 => 'yes', 5 => 'no', 5 => 'yes']
正如您所看到的，您有兩個(gè)5無效的數(shù)字鍵，因此第二個(gè)數(shù)字鍵會(huì)覆蓋第一個(gè)數(shù)字鍵，最終得到
[3 => 'yes', 5 => 'yes']
而你失敗array_search了no，因此你沒有得到任何結(jié)果。在任何獲得復(fù)制值的地方都會(huì)遇到這個(gè)問題。
無論如何，我不確定你為什么要采取這種方法。看來你無論如何都有你想要的數(shù)字$v：
$search = ['gross' => 'yes'];
foreach ($results as $k => $v) {
echo "key $k<br>" . PHP_EOL;
if ($v['gross'] == $search['gross'] ) {
$location_fees = $v['location_fees'];
echo "The location fees: ". $location_fees ." % <br><br>" . PHP_EOL;
$gross_percentage = $v['gross_percentage'];
echo "The gross_percentage is: ".$gross_percentage ."% <br><br>" . PHP_EOL;
} else {
$tran_perc = $v['transaction_percentage'];
echo "The locations percentage is: ".$tran_perc ." % <br>" . PHP_EOL;
$the_loc = $v['location'];
echo "The location is: ".$the_loc ." <br>" . PHP_EOL;
$location_fees = $v['location_fees'];
echo "The location fees: ". $location_fees ." % <br><br>" . PHP_EOL;
}
}
輸出：
key 0<br>
The location fees: 3 % <br><br>
The gross_percentage is: 25% <br><br>
key 1<br>
The locations percentage is: 24 % <br>
The location is: 5 <br>
The location fees: 5 % <br><br>
key 2<br>
The location fees: 5 % <br><br>
The gross_percentage is: 10% <br><br>
