再次 - 抱歉過(guò)去的愚蠢解釋......我沒(méi)有得到我的錯(cuò)誤，這讓我發(fā)瘋......所以我有兩個(gè)數(shù)組——一個(gè)是普通數(shù)組，另一個(gè)是多維數(shù)組。但這也許無(wú)關(guān)緊要，因?yàn)槲曳纸饬藘蓚€(gè)要與數(shù)組進(jìn)行比較的字符串...這是我的代碼：<?php$arr1 = ["folds" => '01,03,'];if($arr1['folds'][strlen($arr1['folds'])-1] == ","){ $arr1['folds'] = substr($arr1['folds'], 0, -1);}$check = explode(",", $arr1['folds']);$arr2 = [ ["Offer" => "Website", "folds" => '01'], ["Offer" => "Development", "folds" => '01,03,05,10,14,15,21,22,'], ["Offer" => "Testing", "folds" => '01,03,04,10,15,22'], ["Offer" => "Sales", "folds" => '01,03,10,22,']];$arr3 = [];foreach($arr2 as $i_arr){ if($i_arr['folds'][strlen($i_arr['folds'])-1] == ","){ $i_arr['folds'] = substr($i_arr['folds'], 0, -1); } $tocheck = explode(",", $i_arr['folds']); foreach($check as $chk){ if(in_array($chk, $tocheck)){ $arr3[] = $i_arr; } }}print_r($arr3);?>所以我至少有兩個(gè)數(shù)組（$check 和 $tocheck）- $check 內(nèi)容搜索或過(guò)濾值就像你想命名的那樣。$tocheck 來(lái)自于數(shù)據(jù)庫(kù)，得到要過(guò)濾的信息。我的代碼沒(méi)有按照我的意愿執(zhí)行 - 因?yàn)?in_array($check[x], $tocheck[y]) 檢查 $check 中的所有值和 $tocheck 中的所有值 - 但是當(dāng)只有一個(gè)值適合時(shí)它說(shuō)“真的”。我的挑戰(zhàn)是當(dāng) $check 中的所有值也在 $tocheck 中時(shí)，只在 $arr3 中打印 $i_arr，而不是只打印一個(gè)...有人有想法嗎？

循環(huán)并$arr2檢查strpos()：$arr1["folds"]
<?php
$arr1 = ["folds" => '02,04'];
$arr2 = [
["Offer" => "Website", "folds" => '02'],
["Offer" => "Development", "folds" => '02,04,09']
];
$arr3 = [];
foreach($arr2 as $i_arr){
if(isset($i_arr["folds"]) && strpos($i_arr["folds"], $arr1["folds"]) > -1){
$arr3[] = $i_arr;
}
}
print_r($arr3);
?>
輸出：
Array
(
[0] => Array
(
[Offer] => Development
[folds] => 02,04,09
)
)

這里的解決方案 - 也許它會(huì)幫助別人：
<?php
// Your code here!
$arr1 = ["folds" => '01,03,'];
if($arr1['folds'][strlen($arr1['folds'])-1] == ","){
$arr1['folds'] = substr($arr1['folds'], 0, -1);
}
$check = explode(",", $arr1['folds']);
$arr2 = [
["Offer" => "Website", "folds" => '03'],
["Offer" => "Development", "folds" => '01,03,05,10,14,15,21,22,'],
["Offer" => "Testing", "folds" => '01,03,04,10,15,22'],
["Offer" => "Sales", "folds" => '01,03,10,22,']
];
$use = "no";
$arr3 = [];
foreach($arr2 as $i_arr){
if($i_arr['folds'][strlen($i_arr['folds'])-1] == ","){
$i_arr['folds'] = substr($i_arr['folds'], 0, -1);
}
$tocheck = explode(",", $i_arr['folds']);
foreach($check as $chk){
if(in_array($chk, $tocheck)){
$use = "yes";
} else {
$use = "no";
break;
}
}
if($use == "yes"){
$arr3[] = $i_arr;
}
}
print_r($arr3);
?>
