Php 我的json对象只输出一个对象，但xml文件中还有更多的对象

这是我的JSON输出，我会喜欢更多的对象

[
    {
        "EcommerceProductGuid": "1282174A-F6A9-4049-8C03-EFDBF065A22F",
        "ProductNumber": "-004394",
        "Description": "Sparta Ion DLI D50",
        "Type": "Ion DLI M-Gear",
        "Kind": "Elektrische fiets",
        "Brand": "Sparta",
    }
]

这是我的PHP

function XMLtoJSON($xml) {
    $xml = file_get_contents($xml);    // gets XML content from file
    $xml = str_replace(array("\n", "\r", "\t"), '', $xml);    // removes newlines, returns and tabs

    // replace double quotes with single quotes, to ensure the simple XML function can parse the XML
    $xml = trim(str_replace('"', "'", $xml));
    $simpleXml = simplexml_load_string($xml);


    // loop over Products -> Product item in the xml file
    $devices = array();
    foreach($simpleXml->Products->Product as $product)
    {

        $device = array();
        foreach($product as $key => $value)
        {
            //$device[(string)$rewriteKeys[$key]] = (string)$value;
            $device[(string)$key] = (string)$value;

            // unset empty and extra keys
            unset($device['epg']);
            unset($device[null]);
        }


    $devices[] = $product;

    return stripslashes(json_encode($devices, JSON_PRETTY_PRINT));    // returns a string with JSON object
}

问题是，他只输出一个产品对象，但我的XML文件包含其中的4个对象。

在脚本末尾有一些问题，您需要将设备添加到主循环内的数组中，但在所有循环结束后输出JSON（您可以在第一个循环结束时返回数据）

---

您缺少第一个

foreach

的结束

}

。因此，

返回总是在第一个
foreach
的第一个循环中执行：

function XMLtoJSON($xml) {
    $xml = file_get_contents($xml);    // gets XML content from file
    $xml = str_replace(array("\n", "\r", "\t"), '', $xml);    // removes newlines, returns and tabs

    // replace double quotes with single quotes, to ensure the simple XML function can parse the XML
    $xml = trim(str_replace('"', "'", $xml));
    $simpleXml = simplexml_load_string($xml);


    // loop over Products -> Product item in the xml file
    $devices = array();
    foreach($simpleXml->Products->Product as $product)
    {

        $device = array();
        foreach($product as $key => $value)
        {
            //$device[(string)$rewriteKeys[$key]] = (string)$value;
            $device[(string)$key] = (string)$value;

            // unset empty and extra keys
            unset($device['epg']);
            unset($device[null]);
        }
    $devices[] = $product;
    } // THIS WAS MISSING

    return stripslashes(json_encode($devices, JSON_PRETTY_PRINT));    // returns a string with JSON object
}

在for循环外部返回json数据，然后查看结果您的意思是在函数外部吗？但我认为他已经在循环之外了，对吗？不是在函数之外，循环的终点在哪里
function XMLtoJSON($xml) {
    $xml = file_get_contents($xml);    // gets XML content from file
    $xml = str_replace(array("\n", "\r", "\t"), '', $xml);    // removes newlines, returns and tabs

    // replace double quotes with single quotes, to ensure the simple XML function can parse the XML
    $xml = trim(str_replace('"', "'", $xml));
    $simpleXml = simplexml_load_string($xml);


    // loop over Products -> Product item in the xml file
    $devices = array();
    foreach($simpleXml->Products->Product as $product)
    {

        $device = array();
        foreach($product as $key => $value)
        {
            //$device[(string)$rewriteKeys[$key]] = (string)$value;
            $device[(string)$key] = (string)$value;

            // unset empty and extra keys
            unset($device['epg']);
            unset($device[null]);
        }
    $devices[] = $product;
    } // THIS WAS MISSING

    return stripslashes(json_encode($devices, JSON_PRETTY_PRINT));    // returns a string with JSON object
}
