使用 php 從 json 獲取特定值

Question

我只需要從一個鍵中獲取特定值，例如：

我"odd": "6.25"從

"name": "Team To Score Last"->"value": "No goal"

和奇數

這是我的 json

"response": [
    {
    "league": {},
    "fixture": {},
    "update": "2020-05-15T09:49:32+00:00",
    "bookmakers": [
        {
        "id": 6,
        "name": "Bwin",
        "bets": [
            {}, {}, {}, {}, {}, {}, {},
            {}, {}, {}, {},
            {    
                "id": 15,
                "name": "Team To Score Last",
                "values": [
                        {
                            "value": "No goal",
                            "odd": "6.25"
                        }

我試過了

$odds =json_decode($responseodds, true);
$value=$odds['response'][0]['bookmakers'][0]['bets'][0]['name'];

不幸的是，我只得到了最后一個得分的團隊

Answer 1

遍歷 bets 數組，並查找您感興趣的投注name 。

foreach ( $odds['response'][0]['bookmakers'][0]['bets'] as $bet){
    if ( $bet['name'] == "Team To Score Last") {
        // this is the one
        echo 'The odds were ' . $bet['values'][0]['odd'];
    }
}

如果你想為所有博彩公司提供這些賠率

foreach ( $odds['response'][0]['bookmakers'] as $bookie){

    foreach ( $bookie as $bet){
        if ( $bet['name'] == "Team To Score Last") {
            // this is the one
            echo 'The bookie ' . $bookie['name'] . 'has the odds ' . $bet['values'][0]['odd'];
        }
    }
}

<?php
if (isset($_POST["submit"])){
    include 'config.php'; 


   $name = mysql_real_escape_string($conn, $_POST["name"]);
   $email = mysql_real_escape_string($conn, $_POST["email"]);   
   $password = mysql_real_escape_string($conn, $_POST["password"]);
   $cpassword = mysql_real_escape_string($conn, $_POST["cpassword"]);  
   $roles = mysql_real_escape_string($conn, $_POST["roles"]);
   $roles_used = 0;

   if (mysql_num_rows(mysqli_query($conn, "SELECT * FROM users WHERE email='{$email}'")) > 0){
        echo "<script> alert('{$email} - This email is already used.');</script>";
   } else {
        if ($password === $cpassword){
                $sql = "INSERT INTO users (name, email, password, roles, roles_used) VALUES ('{$name}', '{$email}', '{$password}', '{$roles}', '{$roles_used}')";
                $result = mysql_query($conn, $sql);

                if ($result){
                        header("Location: login.html");

                }else{
                    echo "<script>Error: ".$sql.mysql_error($conn)." </script>";    
                }
        }else{
                echo "<script>alert('Passwords do not match.');</script>";
        }
   }
}

我正在嘗試運行此代碼，但在本地主機上它只是作為代碼行返回。 可能是什么問題？

$data = json_decode($json, true);

$bets = $data['response'][0]['bookmakers'][0]['bets'];

foreach ($bets as $item) {

    $odd = $item['values'][0]['odd'];

    var_dump($item);
