Question

每当我在PHP脚本中包含某个文件时，它就会破坏代码并仅加载样式表。我不确定是什么原因引起了这个问题。它是由依赖引起的吗？我不确定PHP是否继承了值等。

search.php调用tablegen.php中的函数。

include 'tablegen.php';

tablegen.php创建一个变量，然后返回它。

现在，我想将此变量传递给email.php中的函数。但是，当我这样做时：

include 'email.php';

这会打破“tablegen.php”中的php脚本，只会打开一个背景加载的空白页面。

感谢您对此问题的任何见解。

Answer 1

我是由Evil Faires引起的，它们也被称为Exceptions，Warnings和Fatal Errors。它们是隐形的（所以你看不见，是的，看不到!!!），你需要使用一些神奇的环境才能看到这些繁琐，所以：

error_reporting(-1); // display all faires
ini_set('display_errors', 1);  // ensure that faires will be seen
ini_set('display_startup_errors', 1); // display faires that didn't born

Answer 2

这个答案与我在回复“我不是拖延”时发布的评论有关，而不是当前问题中的代码（当您对代码有疑问时，您应该发布包含问题的版本）。

$output是tableGen()函数中的局部变量。您无法在函数外部访问它（除非您使用global声明它，但在这种情况下没有理由这样做）。该功能以：

结束

return $output

这意味着您可以将函数调用的结果分配给search.php中的变量，例如

$result = tableGen($x);
sendEmail($output);

这与使用include无关，如果所有函数都在主search.php文件中，则会遇到同样的问题。变量范围基于类和函数，而不是文件。

包括文件中断php脚本
