php循环输出数组 json,php循环通过json数组(php loop through json array)
php循環通過json數組(php loop through json array)
我有一個像這樣的json字符串：
$fields_string = '
{"fields":
{"customers":[{"name":"john","id":"d1"},
{"name":"mike","id":"d2"},
{"name":"andrew","id":"d3"},
{"name":"peter","id":"d4"}]
}
}'
我該如何打印每個名字？ 稍后我將在html選項中使用它們，我知道如何做到這一點。 但是我無法把繩子拿出來。 這是我嘗試過的東西：
$obj = json_decode($fields_string);
$fields_detail = $obj-?{"fields"}->{"customers"};
在這一點上，我能夠通過echo json_encode($fields_detail)打印出客戶數組，但在此之前，我希望使用foreach來echo json_encode($fields_detail)名稱。 我試了好幾次，但沒辦法。 任何人都可以幫忙。
謝謝！
I have a json string like this:

{"customers":[{"name":"john","id":"d1"},
{"name":"mike","id":"d2"},
{"name":"andrew","id":"d3"},
{"name":"peter","id":"d4"}]
}
}'
How can I print each name? I will use them later in a html select options, I know how to do that. But I couldn't get the string out. Here are something I tried:
$obj = json_decode($fields_string);
$fields_detail = $obj-?{"fields"}->{"customers"};
at this point, I am able to print the customer array out by echo json_encode($fields_detail), but before that, I want to get the name break down using foreach. I tried several times, it didn't work. Can anyone help please.
Thanks!

最滿意答案
客戶是一個對象數組，因此迭代每個對象并讀取屬性應該有效。
foreach ($fields_detail as $customer) {
echo $customer->name;
}
Customers is an array of objects so iterating over each object and reading the property should work.
foreach ($fields_detail as $customer) {
echo $customer->name;
}

如果需要關聯數組，請將第二個函數參數設置為true 如果您需要關聯數組，某些版本的php需要第2個參數 $json = '[{"var1":"9","var2":"16","var3":"16"},{"var1":"8","var2":"15","var3":"15"}]';
$array = json_decode( $json, true );

json_decode()不返回數組。 要做到這一點，你需要做json_decode($_REQUEST['names'], true) http://php.net/manual/en/function.json-decode.php json_decode() doesn't return an array. To get it to do so you'd need to do json_decode($_REQUEST['names'], true) http://php.net/manu

你正在訪問一個數組。 您使用[]執行此操作，而不是使用{} 。 要獲得令牌數組，您需要$json2['reply1']['tokens'] 。 同樣，您使用[]訪問此數組中的各個項目，而不是-> 。 使用$laa->token; 將再次失敗。 請嘗試以下方法 $tokens = $json2['reply1']['tokens'];
foreach ($tokens as $token) {
echo $token['token']
}
You're accessing an array.

在循環內試試這個： if(isset($row['tableDet'])){// or !is_null() or is_numeric()
$tableDet = "occupied";

一旦你在php中把一個關聯數組編碼成一個JSON對象，它不再是一個數組，它是一個帶有鍵和值的對象。 您可以使用for..in在javascript中迭代它們 for (var key in obj) {
console.log(obj[key]);
}
注意： for..in不是garuntee順序，如果你需要確保順序，你將不得不使用你的數組索引，而不是key=>value ，而是使用for循環(或while )。 Once you encode an associative array

每次進入循環時，都會覆蓋您的數組 嘗試： $json1[] = array(); $json2[] = array(); $this->db->sql = "SELECT ID AS ID, WebsiteName AS SelectText, WebsiteCode AS SelectValue FROM Banners_Websites ORDER BY WebsiteName";
