PHP结合变量和数组值

Question

我有一个数组。我想用数组值生成动态变量。当我运行下面的代码时，它不起作用。我想生成$urlsHome和$urlsOffice。我该怎么办？

$arr= ["Home", "Office"];

foreach ($arr as $key=>$type) {
    echo $urls.type;
}

Answer 1

您必须使用这个很好的{}括号。

$urlsHome="this";
$urlsOffice="that";

$arr= ["Home", "Office"];

foreach ($arr as $key=>$type) {
    echo ${'urls'.$type}."<BR>";
}

结果：

Answer 2

我相信那是您想要的。

$arr = ["Home", "Office"];

foreach ($arr as $key=>$type) {
    ${'url' . $type} = $type;
    echo $urlHome;
}

这是在PHP中创建动态变量的简单方法。
