Question

我正在尝试更好地组织我的“行动”，目前这是一个包含大量案例的巨型转换声明，并且很难管理。我想将操作移动到可以更轻松管理的文件中。但我正试图解决一个问题。

我有一个foreach循环遍历所有“被调用的动作”并调用它们。然后我有一堆动作，但是我希望结束当前循环的执行（即continue;或break;），但这似乎不适用于包含的文件。

我还能做到这一点吗？我还需要“操作”才能访问执行脚本中定义的所有当前变量（这就是我选择包含的原因）。

目前...

included_file.php

<?php
blah blah stuff
if(statement) {
   // accesses variables declared in calling_file.php
   continue;
}
?>

calling_file.php

<?php
blah blah stuff
// declare variables that need to be accessed in included_files.php
foreach() {
include included_file.php
}
?>

现在我想停止当前循环并转到下一个循环。有什么想法吗？

如果我正确理解了您的问题，您似乎希望从包含的文件中获取结果，该文件表明您要执行的操作（break，continue），然后使用简单的switch语句内循环到break外循环。 break control structure将允许您执行此操作。

<强> calling_file.php

<?php

$includes = array ('included_file1.php', 'included_file2.php', 'included_file3.php');

const CONTROL_BREAK = 3;
const CONTROL_CONTINUE = 7;

// declare variables that need to be accessed in included_files.php
foreach($includes as $include) {
    print "Including $include\n";
    $result = include($include);
    switch ($result){
        case CONTROL_BREAK:
            break 2;

        case CONTROL_CONTINUE:

        default:
            continue 2;
    }
}

<强> included_file1.php

<?php
print __FILE__ . " has been included!\n";

if(TRUE) {
   print "I should continue!\n";
   return CONTROL_CONTINUE;
}

<强> included_file2.php

<?php
print __FILE__ . " has been included!\n";

if(TRUE) {
   print "I should break!\n";
   return CONTROL_BREAK;
}

<强> included_file3.php

<?php
print __FILE__ . " has been included!\n";

if(TRUE) {
   print "You should never see me!";
}

从包含文件中断出循环？
