Question

我正在尝试使用XML文件更新MySQL表。

但是当我在底部运行print_r($key);时，从0开始的键累加1直到最后一个产品，即3640，但键应该是我的股票代码。请有人帮忙:)）

我的php代码如下所示：

<?php
$link = mysql_connect("localhost", "username", "password","db") or    die("Could not connect.");
$xml = simplexml_load_file( 'http://www.placeofmyxml.com/myxml.xml' );
$xpath = $xml->xpath( '//Product' );

$feed = array();
foreach( $xpath as $node ) {
    $feed[(string)$key->StockCode] = (int)$node->ProdQty;
}

foreach( $xpath as $key => $node ) {
    $sql = 'UPDATE products SET quantity="'.$node.'" WHERE model="'.$key.'"';
    print_r($key);
    $run = mysql_query( $sql, $link );
}
?>

XML看起来像这样：

Answer 1

在您提供的代码中，您在分配任何内容之前使用$key：

foreach( $xpath as $node ) {
    $feed[(string)$key->StockCode] = (int)$node->ProdQty;
}

这可能是导致问题的原因。如果我删除此循环，$key确实会增加。

使用PHP
