以下是我制作数组的方法:
if($Love != " "){
$LoveArray['Couple'] = $Love;
}
上面的行是while循环。当我print_r($LoveArray);
时,我收到以下输出:
数组([Couple] => 5726)数组([Couple] => 3421)数组([Couple] => 3421)阵列([Couple] => 3421)阵列([Couple] => 2213)阵列([Couple] => 2213)阵列([Couple] => 5339)阵列([Couple] => 5339)数组([Couple] => 3910)数组([Couple] => 3910)数组( [夫妻] => 3910)阵列([Couple] => 3910)阵列([Couple] => 3910 )Array([Couple] => 3910)Array([Couple] => 3910)Array( [夫妻] => 3910)阵列([Couple] => 3421)阵列([Couple] => 5726 )Array([Couple] => 2213)Array([Couple] => 2213)Array( [夫妻] => 2213)阵列([Couple] => 2213)阵列([Couple] => 2213 )Array([Couple] => 2213)Array([Couple] => 2213)Array( [夫妻] => 2213)阵列([Couple] => 2213)阵列([Couple] => 2213 )Array([Couple] => 2213)Array([Couple] => 2213)Array( [夫妻] => 6327)阵列([Couple] => 6327)阵列([Couple] => 3910 )Array([Couple] => 3910)Array([Couple] => 3910)Array( [夫妻] => 3910)阵列([Couple] => 3910)阵列([Couple] => 3910 )Array([Couple] => 3910)Array([Couple] => 3910)Array( [夫妻] => 3910)阵列([Couple] => 5339)阵列([Couple] => 5339 )Array([Couple] => 6327)Array([Couple] => 6327)Array( [夫妻] => 6327)阵列([Couple] => 6327)阵列([Couple] => 6327 )
上面的数组可以表示为:
<?php
$array = [
["Couple" => 5726],
["Couple" => 3421],
["Couple" => 3421],
["Couple" => 3421],
["Couple" => 2213],
["Couple" => 2213],
["Couple" => 5339],
["Couple" => 5339],
["Couple" => 3910],
["Couple" => 3910],
["Couple" => 3910],
["Couple" => 3910],
["Couple" => 3910],
["Couple" => 3910],
["Couple" => 3910],
["Couple" => 3910],
["Couple" => 3421],
["Couple" => 5726],
["Couple" => 2213],
["Couple" => 2213],
["Couple" => 2213],
["Couple" => 2213],
["Couple" => 2213],
["Couple" => 2213],
["Couple" => 2213],
["Couple" => 2213],
["Couple" => 2213],
["Couple" => 2213],
["Couple" => 2213],
["Couple" => 2213],
["Couple" => 6327],
["Couple" => 6327],
["Couple" => 3910],
["Couple" => 3910],
["Couple" => 3910],
["Couple" => 3910],
["Couple" => 3910],
["Couple" => 3910],
["Couple" => 3910],
["Couple" => 3910],
["Couple" => 3910],
["Couple" => 5339],
["Couple" => 5339],
["Couple" => 6327],
["Couple" => 6327],
["Couple" => 6327],
["Couple" => 6327],
["Couple" => 6327],
];
正如您所看到的,有些值正在重复,其中一个是5726
。
我如何检查5726
中是否已$LoveEvent['Couple']
,以及是否在此数组中不插入另一个?{/ p>
亲切的问候。

如果需要检查数组中是否存在值,则首选使用in_array()。
但是到目前为止,您需要检查它是否为多维数组,以便您可以以递归方式使用in_array(),以便它可以用于查找值是否存在于数组中。
<?php
function check_array_value($to_find, $array_values, $strict = false) {
foreach ($array_values as $item) {
if (($strict ? $item === $to_find : $item == $to_find) || (is_array($item) && check_array_value($to_find, $item, $strict))) {
return true;
}
}
return false;
}
?>
可以像这样使用此功能。
$array_values = array(array("Name", "Apple"), array("Orange", "IOS"));
echo check_array_value("IOS", $array_values) ? 'found' : 'not found';
如果数组中存在IOS
,它将返回found
,否则它将返回not found
。

可能是这样的:
foreach($LoveArray as $value){
if($value['Couple'] != $Love){
$LoveArray['Couple'] = $Love;
}
}
答案 2 :(得分:0)
if ($Love != " ") {
if (!in_array($Love, array_column($LoveArray, 'Couple'))) {
$LoveArray['Couple'] = $Love;
$finalArray[] = $LoveArray; //adding the new element should also be here
}
}
需要 (PHP 5&gt; = 5.5.0,PHP 7) http://php.net/manual/en/function.array-column.php
$arr = ['orange', 'apple', 'banana', 'orange', 'banana'];
$finalArray = [];
foreach ($arr as $item) {
if (!in_array($item, array_column($finalArray, 'Couple'))) {
$finalArray[] = ['Couple' => $item];
}
}
print_r($finalArray);
输出:
Array
(
[0] => Array
(
[Couple] => orange
)
[1] => Array
(
[Couple] => apple
)
[2] => Array
(
[Couple] => banana
)
)

下面是一个基于foreach
的简单解决方案,您可能想尝试一下。顺便说一下,你可以Quick-Test it here:
<?php
$array = [
["Couple" => 5726],
["Couple" => 3421],
["Couple" => 3421],
["Couple" => 3421],
["Couple" => 2213],
["Couple" => 2213],
["Couple" => 5339],
["Couple" => 5339],
["Couple" => 3910],
["Couple" => 3910],
["Couple" => 3910],
["Couple" => 3910],
["Couple" => 3910],
["Couple" => 3910],
["Couple" => 3910],
["Couple" => 3910],
["Couple" => 3421],
["Couple" => 5726],
["Couple" => 2213],
["Couple" => 2213],
["Couple" => 2213],
["Couple" => 2213],
["Couple" => 2213],
["Couple" => 2213],
["Couple" => 2213],
["Couple" => 2213],
["Couple" => 2213],
["Couple" => 2213],
["Couple" => 2213],
["Couple" => 2213],
["Couple" => 6327],
["Couple" => 6327],
["Couple" => 3910],
["Couple" => 3910],
["Couple" => 3910],
["Couple" => 3910],
["Couple" => 3910],
["Couple" => 3910],
["Couple" => 3910],
["Couple" => 3910],
["Couple" => 3910],
["Couple" => 5339],
["Couple" => 5339],
["Couple" => 6327],
["Couple" => 6327],
["Couple" => 6327],
["Couple" => 6327],
["Couple" => 6327],
];
$arrFinal = [];
foreach($array as $iKey=>$arrCouple){
if(!in_array($arrCouple, $arrFinal)){
$arrFinal[] = $arrCouple;
}else{
// DO WHATEVER YOU WANT TO DO
// IN THE CASE THE DATA DOES ALREADY EXIST...
// THIS WOULD BE UP TO YOU...
}
}
var_dump($arrFinal);
var_dump($arrFinal);
