内容图文

当你需要包含一个文件时,只需使用“include file”,当你需要返回一个配置文件时,你必须使用“return include file”…
通常我有一个函数“loader($file,$return = false)”,其中我使用$return返回include或不.
我的问题是,即使对于未配置的文件,如果保持返回包含文件存在问题：

return include "class/view.php"
return include "config/test.php"

谢谢

解决方法:

从php.net开始：

Handling Returns: include returns FALSE on failure and raises a
warning. Successful includes, unless overridden by the included file,
return 1. It is possible to execute a return statement inside an
included file in order to terminate processing in that file and return
to the script which called it. Also, it’s possible to return values
from included files. You can take the value of the include call as you
would for a normal function. This is not, however, possible when
including remote files unless the output of the remote file has valid
PHP start and end tags (as with any local file). You can declare the
needed variables within those tags and they will be introduced at
whichever point the file was included.

如果您的类/ view.php或config / test.php使用return,那么您可以保留它.如果这些文件中没有return,则没有理由,除非您要阻止当前脚本进一步执行.

例1：

<?php
echo 1;  // < executes

return include 'somefile.php';  // < script will end here because of "return"

echo 2;  // < not executes ever
?>

例2：

<?php
echo 1;  // < executes

include 'somefile.php';  // < executes

echo 2;  // < executes
?>
