我有一个数组（$ items）：http://vilavaleaprahovei.ro/kimea/allMarks.php
我如何搜索是否找到3个值：“ marca”，“ diametru”和“ latime”（不仅是其中的一个或只有两个，还应该全部建立三个）并将其返回？
我当时就是这样：
foreach($items as $key => $value) {
if(($key['marca'] == "ALCAR STAHLRAD") && ($value['diametru'] == 15) && ($value['latime']== 7)) {
echo $key['marca'];
echo $value['diametru'];
echo $value['latime'];
} else {
echo "Not found any product";
}
}

答案 0 :(得分：1)
请注意，在您的代码上，您尝试将$key作为数组访问，但这是一个字符串：$key['marca']。数组键不能是数组。
由于您的数组结构，您可能需要这样做（如果我对您的问题很了解）
// The items that you are searching
$marca = 'ALCAR STAHLRAD';
$diametru = 15;
$latime = 7;
// The default is that nothing was found.
$found = false;
// First we check if there's an item with the given $marca
if (array_key_exists($marca, $items)) {
$item = $items[$marca];
// Now we check if diametru and latime exists.
// I stored it on variables to make easier to understand.
// ----------
// `in_array()` search for values inside the array.
// If the value that you are searching is not a item,
// but an array key, then use `array_key_exists`.
$diametruExists = in_array($diametru, $item['diametru']);
$latimeExists = in_array($diametru, $item['diametru']);
// If both $diametruExists and $latimeExists are true
// we set that $found is true.
if ($diametruExists && latimeExists) {
$found = true;
}
}
if ($found) {
echo $marca;
echo $diametru;
echo $latime;
} else {
echo "Not found any product";
}
此解决方案的缺点是您无法获得其他值，例如pcd，只需检查给定的组合是否存在。
