PHP：迭代另一个函数的结果并输出的函数

发布于 2024-11-27 00:31:45 字数 733 浏览 2 评论 0原文

看起来这很简单，但是，我遇到了一个问题：

代码如下：

function getValidCustomers() {
    global $db;
    $getCustomers = $db->GetAll("SELECT * from customers where CustomerActive='1' AND protected IS NULL or protected=0;");
    foreach($getCustomers as $customer) {
        echo $customer['CustomerID']."\n";
    }
}

function updateValidCustomers() {
    $customers = getValidCustomers();
    for ($i = 0; $i < sizeof($customers); $i++) {
        echo "DEBUG: $customers[$i]\n";
    }
}

updateValidCustomers();

基本上，现在的输出是 CustomerID 列表（来自 updateValidCustomers()）。我只想 updateValidCustomers() 从 getValidCustomers() 获取数据，然后循环遍历它，以便我可以对其运行另一个查询来实际操作数据库。

有什么想法吗？

Seems like this would be pretty simple, however, I'm running into an issue:

Here's the code:

function getValidCustomers() {
    global $db;
    $getCustomers = $db->GetAll("SELECT * from customers where CustomerActive='1' AND protected IS NULL or protected=0;");
    foreach($getCustomers as $customer) {
        echo $customer['CustomerID']."\n";
    }
}

function updateValidCustomers() {
    $customers = getValidCustomers();
    for ($i = 0; $i < sizeof($customers); $i++) {
        echo "DEBUG: $customers[$i]\n";
    }
}

updateValidCustomers();

Basically, the output right now is a list of the CustomerIDs (from updateValidCustomers()). I just want updateValidCustomers() to get the data from getValidCustomers() and then loop through it, so that I can run another query on it that will actually manipulate the database.

Any ideas?

getValidCustomers 不返回任何内容，也许您的意思是：

function getValidCustomers() {
    global $db;
    $getCustomers = $db->GetAll("SELECT * from customers where CustomerActive='1' AND protected IS NULL or protected=0;");
    foreach($getCustomers as $customer) {
        echo $customer['CustomerID']."\n";
    }
    return $getCustomers;
}

getValidCustomers doesn't return anything, maybe you mean this:

function getValidCustomers() {
    global $db;
    $getCustomers = $db->GetAll("SELECT * from customers where CustomerActive='1' AND protected IS NULL or protected=0;");
    foreach($getCustomers as $customer) {
        echo $customer['CustomerID']."\n";
    }
    return $getCustomers;
}
