在 echo <script> 内容中传递 PHP 变量

Question

我正在尝试将 $php_variable 传递给 JavaScript 内容 在一个 php 文件 的 echo 标签中。这是因为我希望通过window.location.

将查询值从old_page_url追加到new_page_url

例如，

http://example/?data=1234 到 http://example/something-else/1234

我的代码片段：

<?php

$php_variable = "testing";
echo "<script>";
echo "var toURL = 'http://example.com/something-else/'";
echo "window.location = toURL + $php_variable";
echo "</script>";

我试过：

<?php

$php_variable = "testing";
echo "<script>";
echo "var toURL = 'http://example.com/something-else/'";
echo "window.location = toURL + json_decode($php_variable)";
echo "</script>";

和

<?php

$php_variable = "testing";
echo "<script>";
echo "var toURL = 'http://example.com/something-else/'";
echo "window.location = toURL + <?php echo $php_variable; ?>";
echo "</script>";

但这两个都不行。有什么想法吗？

这个怎么样

<?php
$php_variable = "testing";
echo "<script>";
echo "var toURL = 'http://example.com/something-else/'";
echo "window.location = toURL +" . "'{$php_variable}'";
echo "</script>";

echo "window.location = 'http://example.com/something-else/$php_variable'";
