在数组PHP中搜索

我想在以下数组中创建一个搜索函数：

array(      
    array("key" => "net_sale",         "value" => "NET SALE CRTN"),
    array("key" => "productive_calls", "value" => "Productive Calls"),
    array("key" => "drop_size_value",  "value" => "DROP SIZE VALUE"),
    array("key" => "sku",              "value" => "SKU PER BILL"),
    array("key" => "net_amount",       "value" => "Net Amount"),
    array("key" => "drop_size_crtn",   "value" => "DROP SIZE CRTN"),
    array("key" => "productive_pops",  "value" => "PRODUCTIVE POPS"),
    array("key" => "scheduled_pops",   "value" => "SCHEDULED POPS") 
);

---

此函数将返回搜索的任何键的位置。（例如，对于搜索“净额”，它将返回4）

创建一个数组，其中键实际上是键，值是值

$map = array();
for ($i = 0; $i < count($values); $i++) {
    $value = $values[$i];
    $map[$value['key']] = $i;
}

$net_amount_pos = $map['net_amount'];

$map=array（）；
对于（$i=0；$i

然后你可以直接拔出密钥，而不需要搜索它……

我同意关于这个问题的评论，我不认为你目前存储数据的方式是最好的。尽管如此，只需循环遍历每个数组，并检查其中是否包含要搜索的字符串

function search($array,$key_value) {
   foreach($array AS $key => $value) {
     if($value['key'] == $key_value) return $key;
   }
}
echo search($arr,'net_amount'); //$arr contains the array you gave as example

function searchArrays($search){
    $return = array();
    $data = array(      
        array("key" => "net_sale",         "value" => "NET SALE CRTN"),
        array("key" => "productive_calls", "value" => "Productive Calls"),
        array("key" => "drop_size_value",  "value" => "DROP SIZE VALUE"),
        array("key" => "sku",              "value" => "SKU PER BILL"),
        array("key" => "net_amount",       "value" => "Net Amount"),
        array("key" => "drop_size_crtn",   "value" => "DROP SIZE CRTN"),
        array("key" => "productive_pops",  "value" => "PRODUCTIVE POPS"),
        array("key" => "scheduled_pops",   "value" => "SCHEDULED POPS") 
    );

    foreach($data as $k => $v){
        if(stristr($v['key'], $search) || stristr($v['value'], $search)){
            $return[] = $k;
        }
    }

    return $return;
};
print_r(searchArrays('net'));

这是以下代码：

$test  = array(      
    array("key" => "net_sale",         "value" => "NET SALE CRTN"),
    array("key" => "productive_calls", "value" => "Productive Calls"),
    array("key" => "drop_size_value",  "value" => "DROP SIZE VALUE"),
    array("key" => "sku",              "value" => "SKU PER BILL"),
    array("key" => "net_amount",       "value" => "Net Amount"),
    array("key" => "drop_size_crtn",   "value" => "DROP SIZE CRTN"),
    array("key" => "productive_pops",  "value" => "PRODUCTIVE POPS"),
    array("key" => "scheduled_pops",   "value" => "SCHEDULED POPS") 
);
$index = keyval($test,"net_amount");

echo $index;
function keyval($test,$val)
{
$i = null;
    foreach($test as $index=>$t)
    {
        //echo $t['key'];
        if($t['key']==$val){ $i = $index;}
    }
    return $i;
}

试试这个-

定义函数

function checkPosition($needle, $arrData)
{
  $i=0;
   foreach($arrData as $data){

      if(in_array($needle,$data))
        { return $i; }

      $i++;
   }


}

echo checkPosition('net_amount',$test);
Output : 4

调用函数-

function checkPosition($needle, $arrData)
{
  $i=0;
   foreach($arrData as $data){

      if(in_array($needle,$data))
        { return $i; }

      $i++;
   }


}

echo checkPosition('net_amount',$test);
Output : 4

还有一种方法：

$array = array(      
    array("key" => "net_sale",         "value" => "NET SALE CRTN"),
    array("key" => "productive_calls", "value" => "Productive Calls"),
    array("key" => "drop_size_value",  "value" => "DROP SIZE VALUE"),
    array("key" => "sku",              "value" => "SKU PER BILL"),
    array("key" => "net_amount",       "value" => "Net Amount"),
    array("key" => "drop_size_crtn",   "value" => "DROP SIZE CRTN"),
    array("key" => "productive_pops",  "value" => "PRODUCTIVE POPS"),
    array("key" => "scheduled_pops",   "value" => "SCHEDULED POPS") 
);

function search($term, $array) {
    for ($i=0; $i<count($array); $i++) {
        if ($array[$i]['key'] == $term) return $i;
    }
}

echo search("net_amount", $array);

$array=array（
数组（“键”=>“净销售额”，“值”=>“净销售额CRTN”），
数组（“键”=>“生产性调用”，“值”=>“生产性调用”），
数组（“key”=>“drop\u size\u value”，“value”=>“drop size value”），
数组（“键”=>“sku”，“值”=>“每张账单的sku”），
数组（“键”=>“净额”，“值”=>“净额”），
数组（“键”=>“放置大小”、“值”=>“放置大小”，
数组（“键”=>“生产性持久性有机污染物”，“值”=>“生产性持久性有机污染物”），
数组（“键”=>“计划的弹出窗口”，“值”=>“计划的弹出窗口”）
);
函数搜索（$term$array）{
对于（$i=0；$i
$data=array）(
数组（“键”=>“净销售额”，“值”=>“净销售额CRTN”），
数组（“键”=>“生产性调用”，“值”=>“生产性调用”），
数组（“key”=>“drop\u size\u value”，“value”=>“drop size value”），
数组（“键”=>“sku”，“值”=>“每张账单的sku”），
数组（“键”=>“净额”，“值”=>“净额”），
数组（“键”=>“放置大小”、“值”=>“放置大小”，
数组（“键”=>“生产性持久性有机污染物”，“值”=>“生产性持久性有机污染物”），
数组（“键”=>“计划的弹出窗口”，“值”=>“计划的弹出窗口”）
);
$search\u key=“sku”；
对于（$count=0；$count听起来不错！您尝试了什么？我在数组中循环搜索，但这不是一种有效的方法。在您的情况下，循环似乎是唯一的选择…顺便说一句，您可能会混淆自己，将每个子数组的第二个键称为“值”，但它仍然只是一个“键”…您正在返回value
key，尽管OP希望将具有该值的数组的编号作为键“key”（如果我理解正确）
$data=array(
    array("key" => "net_sale",         "value" => "NET SALE CRTN"),
    array("key" => "productive_calls", "value" => "Productive Calls"),
    array("key" => "drop_size_value",  "value" => "DROP SIZE VALUE"),
    array("key" => "sku",              "value" => "SKU PER BILL"),
    array("key" => "net_amount",       "value" => "Net Amount"),
    array("key" => "drop_size_crtn",   "value" => "DROP SIZE CRTN"),
    array("key" => "productive_pops",  "value" => "PRODUCTIVE POPS"),
    array("key" => "scheduled_pops",   "value" => "SCHEDULED POPS")
);

$search_key="sku";


for($count=0; $count<=count($data); ++$count)
{

    if(strcmp($data[$count]["key"], $search_key)==0)
    {
        echo $data[$count]["value"];
    }

}
