這是我的 JSON 輸出，我會喜歡更多對象[ { "EcommerceProductGuid": "1282174A-F6A9-4049-8C03-EFDBF065A22F", "ProductNumber": "-004394", "Description": "Sparta Ion DLI D50", "Type": "Ion DLI M-Gear", "Kind": "Elektrische fiets", "Brand": "Sparta", }]這是我的 PHPfunction 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}問題是他只輸出一個 Product 對象，但我的 XML 文件包含其中 4 個。

您在腳本結束時遇到了一些問題，您需要將設備添加到主循環內的數組中，但在所有循環結束后輸出 JSON（您在第一個循環結束時返回數據） .
// 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)$value;
}
// unset empty and extra keys after transferring all values
unset($device['epg']);
unset($device[null]);
// Add device into array inside loop
$devices[] = $product;
}
// Return data after processing all product in loop
return stripslashes(json_encode($devices, JSON_PRETTY_PRINT)); // returns a string with JSON object

你錯過了}第一個結束foreach。因此return總是在 first 的第一個循環內執行foreach：
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
}
