<?xml version="1.0" encoding="UTF-8" ?>
<SMS>
<authentification>
<username>xxxx</username>
<password>xxxx</password>
</authentification>
<recipients>
<number>8309042932</number>
</recipients>
</SMS>
我的号码节点有一个动态生成的数字，适用于不同的人，我想加载所有号码，但只得到最后一个号码。
用于创建 xml 字符串的代码：
<?xml version="1.0" encoding="UTF-8" ?>
$xmlstring =
"<SMS>
<authentification>
<username>xxxx</username>
<password>xxxx</password>
</authentification>
<recipients>";
foreach($gsmnumbers as $number) {
$number = explode(",", $number);
foreach($number as $num) {
$count = count($num);
for($i = 0; $i < $count; $i++) {
$xmlHalf = "<gsm>$num</gsm>";
}
}
}
$xmlSecondHalf = "</recipients> </SMS>";
试试这个，你的代码中的各种错误。
基本上，如果您使用 .= 语法，则可以连接到现有字符串的末尾，只需使用 = 即可将字符串替换为新值。
此外，<?xml version="1.0" encoding="UTF-8" ?>需要在字符串中以将其标识为有效的 XML 字符串。
$xmlstring = '
<?xml version="1.0" encoding="UTF-8" ?>
<SMS>
<authentification>
<username>xxxx</username>
<password>xxxx</password>
</authentification>
<recipients>';
foreach($gsmnumbers as $number) {
$nums = explode(",", $number);
foreach($nums as $num) {
$xmlstring .= "<gsm>$num</gsm>";
}
}
$xmlstring .= "</recipients></SMS>";
不要将 XML 编写为字符串，为此使用 XML 库。在创建 XML 时，库通常会阻止您射入自己的脚。它还使您的代码更具可读性。例：
// process and transform input data
$gsmnumbers = ['1234,5678,9012'];
$gsms = [];
foreach ($gsmnumbers as $number) {
$nums = explode(",", $number);
foreach ($nums as $num) {
$gsms[] = $num;
}
}
// create XML
$request = new SimpleXMLElement('<SMS/>');
$authentication = $request->addChild('authentification');
$authentication->username = 'XXXX';
$authentication->password = 'XXXX';
$recipients = $request->addChild('recipients');
foreach ($gsms as $gsm) {
$recipients->addChild('gsm', $gsm);
}
echo $request->asXML();
示例输出：
<?xml version="1.0"?>
<SMS><authentification><username>XXXX</username><password>XXXX</password></authentification><recipients><gsm>1234</gsm><gsm>5678</gsm><gsm>9012</gsm></recipients></SMS>
