如上所述，我试图检索名为“totalcolumns”的值。但是，我无法检索我的slider.php文件中的值。我还尝试使用链接中建议的会话，但没有成功。有人能告诉我我做错了什么吗？您应该使用html框架集或iFrame，但不应该使用，这是一种不好的做法。如果您不想通过任何更改重新加载整个页面，您应该使用javascript。您应该能够使用$\u会话。这是：
$_SESSION['totalcolumns'] = $columns --> your value here in the first script
your value will be stored in the $columns variable in the second
$columns = $_SESSION['totalcolumns']
顺便说一句，不要使用框架集您可以使用
$\u REQUEST$\u GET<?php
if(array_key_exists('totalcolumns', $_GET)) {
$totalcolumns = $_GET['totalcolumns'];
echo "My next value should get printed";
echo $totalcolumns;
?>
这可能会帮助您我会先识别帧，然后删除第二个帧的src

echo htmlspecialchars（$totalcolumns）
