I am creating an application that uses the MailChimp v3 API, I send off a query to grab all the lists, then I iterate over that array and then iterate over the arrays inside to grab each individual ID and add them to an array. This works perfectly and I get an array with all the correct ID's however I get this error. Warning: Invalid argument supplied for foreach() Am I doing something w
我创建了一个使用MailChimp v3 API的应用程序，我发送了一个查询来获取所有列表，然后遍历该数组，然后遍历数组中的数组以获取每个ID并将它们添加到数组中。 这工作完美，我得到一个数组与所有正确的ID，但是我得到这个错误。 警告：为foreach（）提供的参数无效 我在这里做错了什么？ 即使我正在获取正确的数据 这里是var转储在所有列表上返回的数据，出于安全原因，我已经取出数据，但保留了格式。 http://pastebin.
I want to insert json array data in mysql table. I have written this code. if (mysqli_connect_errno()){ $response["success"] = 0; $response["message"] = "Database Error!"; die(json_encode($response)); echo "Failed to connect to MySQL: " . mysqli_connect_error(); } // Check connection if ($con->connect_error) { die("Connection failed: " . $conn->connect_error); } e
我想在MySQL表中插入json数组数据。 我写了这段代码。 if (mysqli_connect_errno()){ $response["success"] = 0; $response["message"] = "Database Error!"; die(json_encode($response)); echo "Failed to connect to MySQL: " . mysqli_connect_error(); } // Check connection if ($con->connect_error) { die("Connection failed: " . $conn->connect_error); } echo "Connected successfu
there is no issue with this query, as when I use print_r it prints out three different arrays, Im just wondering what Im missing here to get this foreach working, as at the moment Im getting an error... Warning: Invalid argument supplied for foreach() in C:xampphtdocsmyshopadminaccount_list.php on line 11 <?php $account_list = "SELECT * FROM accounts"; $query = $connect->query($account
这个查询没有问题，因为当我使用print_r它打印出三个不同的数组，我只是想知道我在这里错过了什么让这个foreach工作，因为此刻我得到一个错误... 警告：为第11行的C： xampp htdocs myshop admin account_list.php中的foreach（）提供的无效参数 <?php $account_list = "SELECT * FROM accounts"; $query = $connect->query($account_list); while ($final_result = $query->fetch_array(MYSQLI_ASSOC)) { //

我不断收到一个错误数组，我在一个方法中设置了这个错误 这里是代码 public function showerrors() { echo "<h3> ERRORS!!</h3>"; foreach ($this->errors as $key => $value) { echo $value; } } 我一直得到这个“警告：为foreach（）提供的无效参数”当我运行程序，我在这样的构造函数中设置错误数组 $this->errors = array(); 所以我不完全确定它
How get you get element key and value of an at the n position array at a particular position without loop. Imagine $postion = 3; // get array at 3rd position $array = array( "A" => "Four", "B" => "twp", "C" => "three", "D" => "Four", "E" => "Five", "F" => "Four"); $keys = array_keys($array); $value = array_values($array); ech
如何在没有循环的特定位置获得位于n位置数组中的元素key和value 。 想像 $postion = 3; // get array at 3rd position $array = array( "A" => "Four", "B" => "twp", "C" => "three", "D" => "Four", "E" => "Five", "F" => "Four"); $keys = array_keys($array); $value = array_values($array); echo implode(array_slice($keys, $postion, 1)), PHP
Why is an empty foreach loop can change the result. I have the following code: $variable = [1,2,3,4]; foreach ($variable as $key => &$value) $value ++; var_dump($variable); The result I get is: array (size=4) 0 => int 2 1 => int 3 2 => int 4 3 => &int 5 Now, when I add an empty foreach loop like this: $variable = [1,2,3,4]; foreach ($variable as $key =
为什么一个空的foreach循环可以改变结果。 我有以下代码： $variable = [1,2,3,4]; foreach ($variable as $key => &$value) $value ++; var_dump($variable); 我得到的结果是： array (size=4) 0 => int 2 1 => int 3 2 => int 4 3 => &int 5 现在，当我添加一个空的foreach循环像这样： $variable = [1,2,3,4]; foreach ($variable as $key => &$value) $value ++; fo
I want to use a foreach loop with a variable, but this variable can be many different types, NULL for example. So before foreach I test it: if(is_array($var)){ foreach($var as ... But I realized that it can also be a class that implements Iterator interface. Maybe I am blind but how to check whether the class implements interface? Is there something like is_a function or inherits operator
我想用一个带有变量的foreach循环，但是这个变量可以有很多不同的类型，例如NULL 。 因此，在foreach之前我测试它： if(is_array($var)){ foreach($var as ... 但是我意识到它也可以是一个实现Iterator接口的类。 也许我是盲目的，但如何检查类是否实现接口？ 有没有像is_a函数或inherits运算符？ 我发现class_implements ，我可以使用它，但也许有一些更简单？ 第二，更重要的是，我想这个函数存在，足以检查变量is_
This question already has an answer here: How does PHP 'foreach' actually work? 7 answers It's simple, foreach loop is meant to loop through arrays. By setting an array elements, on every single pass through them foreach loop asigns next element value in the array to $value, ie it takes the value of an array element and passes it to a 'basket' calld $value, which in turn
这个问题在这里已经有了答案： PHP'foreach'如何实际工作？ 7个答案 这很简单，foreach循环意味着循环访问数组。 通过设置一个数组元素，通过它们的每一次遍历，foreach循环将数组中的下一个元素值赋值为$ value，即它接受一个数组元素的值并将其传递给'basket'calld $值，当被调用时，它从篮子中获取该值并将其打印在屏幕上。
