Question

请帮助解决这个问题。场景很复杂，但实质上是：

first-file.php的内容

<?php

session_start();

$_SESSION['s_Foo'] = "pippo";

/* this is only a twisted way of producing the header('location: second-file.php'), because unfortunately often I obtain the error "headers already sent". */

echo "<!DOCTYPE html><html>";

echo "<head>&#60;meta charset='utf-8'>&#60;/head>";

echo "<body onload='go()'>";

echo "<script>function go(){location.replace(\"second-file.php\")}</script>";

echo "</body>";

echo "</html>";

exit;

?>

second-file.php的内容

<?php

session_start();

$foo = isset($_SESSION['s_Foo']) ? $_SESSION['s_Foo'] : "nothing";

echo $foo;

...
here a line that require to use $_SESSION['s_Foo']

?>

现在，我读了（在secon文件中）“ pippo ”，但只有一半或一秒...... 然后消失“ pippo ”，并在php日志中写入“ nothing ”，注意：未定义的索引：[...] / second-file.php中的s_Foo第4行

提前谢谢你，弗朗西斯
