blocks|key|1485583|text|想象一下include是什么样子:复制并粘贴包含的PHP文件的内容，然后对其进行解释。作用域根本没有变化，因此您仍然可以直接访问所包含文件中的$someVar+(即使您可能会考虑使用基于类的结构，将$someVar作为参数传递或引用一些全局变量)。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1485584|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Imagine the include as what it is: A copy &amp; paste of the contents of the included PHP file which will then be interpreted. There is no scope change at all, so you can still access $someVar in the included file directly (even though you might consider a class based structure where you pass $someVar as a parameter or refer to a few global variables).

blocks|key|1485648|text|你可以这样做来达到你想要的效果：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1485649|$_GET['id']=$somevar;
include('myFile.php');|code-block|syntax|javascript|1485650|但是，听起来您使用这个include类似于某种函数调用(您提到使用不同的参数重复调用它)。|1485651|在这种情况下，为什么不把它变成一个常规函数，包含一次并多次调用呢？|1485652|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|N|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|O|8|@]|9|@]|A|$]]|$1|I|3|J|5|6|7|P|8|@]|9|@]|A|$]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

You could do something like this to achieve the effect you are after:

<pre><code>$_GET['id']=$somevar;
include('myFile.php');
</code></pre>

However, it sounds like you are using this include like some kind of function call (you mention calling it repeatedly with different arguments).

In this case, why not turn it into a regular function, included once and called multiple times?

blocks|key|1271466|text|在包含的文件中，将html包装在一个函数中。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1271467|<?php+function($myVar)+{?>
++++<div>
++++++++<?php+echo+$myVar;+?>
++++</div>

In the file you include, wrap the html in a function.

<pre><code>&lt;?php function($myVar) {?&gt;
 &lt;div&gt;
 &lt;?php echo $myVar; ?&gt;
 &lt;/div&gt;
&lt;?php } ?&gt;
</code></pre>

In the file where you want it to be included, include the file and then call the function with the parameters you want.

blocks|key|1271510|text|最简单的方法是这样做|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1271511|index.php|1271512|<?php+$active+=+'home';+include+'second.php';+?>|code-block|syntax|javascript|1271513|second.php|1271514|<?php+echo+$active;+?>|1271515|您可以共享变量，因为您使用"include“包含2个文件。|1271516|entityMap^0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|R|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|S|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|T|8|@]|9|@]|A|$]]|$1|K|3|L|5|F|7|U|8|@]|9|@]|A|$G|H]]|$1|M|3|N|5|6|7|V|8|@]|9|@]|A|$]]|$1|O|3|-4|5|6|7|W|8|@]|9|@]|A|$]]]|P|$]]

The simplest way to do this is like this

index.php

<pre><code>&lt;?php $active = 'home'; include 'second.php'; ?&gt;
</code></pre>

second.php

<pre><code>&lt;?php echo $active; ?&gt;
</code></pre>

You can share variables since you are including 2 files by using "include"

blocks|key|1271114|text|我知道这已经有一段时间了，但是，我想知道处理这个问题的最好方法是不是使用be会话变量|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1271115|在你的myFile.php中，你会有|1271116|<?php+

$MySomeVAR+=+$_SESSION['SomeVar'];

session_start();+
$_SESSION['SomeVar']+=+$SomeVAR;

I know this has been a while, however, Iam wondering whether the best way to handle this would be to utilize the be session variable(s)

In your myFile.php you'd have

<pre><code>&lt;?php 

$MySomeVAR = $_SESSION['SomeVar'];

?&gt; 
</code></pre>

And in the calling file 

<pre><code>&lt;?php

session_start(); 
$_SESSION['SomeVar'] = $SomeVAR;
include('myFile.php');
echo $MySomeVAR;

?&gt; 
</code></pre>

Would this circumvent the "suggested" need to Functionize the whole process?

blocks|key|1485777|text|我在处理包含多个字段集的ajax表单时遇到过这种情况。以就业申请为例。我从一个专业参考集开始，我有一个按钮，上面写着“添加更多”。这将使用$count参数执行ajax调用，以再次包含输入集(姓名、联系人、电话..等)，这在第一个页面调用时工作得很好，因为我做了如下操作：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1485778|<?php+

?>|code-block|syntax|javascript|1485779|用户按下一个按钮，让ajax调用ajax('references.php?count=1');，然后在references.php文件中，我有类似这样的东西：|offset|length|style|CODE|1485780|<?php

?>|1485781|我还有其他像这样的动态包含在整个站点中传递参数。当用户按下submit并出现表单错误时，问题就会发生。因此，现在为了避免重复代码来包含那些动态包含的额外字段集，我创建了一个函数，该函数将使用适当的GET参数设置include。|1485782|<?php

function+include_get_params($file)+{

++include($parts[0]);
}
?>|1485783|该函数检查查询参数，并自动将它们添加到$_GET变量中。这在我的用例中运行得很好。|1485784|下面是调用时表单页上的一个示例：|1485785|<?php

I have ran into this when doing ajax forms where I include multiple field sets. Taking for example an employment application. I start out with one professional reference set and I have a button that says "Add More". This does an ajax call with a $count parameter to include the input set again (name, contact, phone.. etc) This works fine on first page call as I do something like:

<pre><code>&lt;?php 
include('references.php');`
?&gt;
</code></pre>

User presses a button that makes an ajax call <code><code>ajax('references.php?count=1');</code></code> Then inside the references.php file I have something like:

<pre><code>&lt;?php
$count = isset($_GET['count']) ? $_GET['count'] : 0;
?&gt;
</code></pre>

I also have other dynamic includes like this throughout the site that pass parameters. The problem happens when the user presses submit and there is a form error. So now to not duplicate code to include those extra field sets that where dynamically included, i created a function that will setup the include with the appropriate GET params.

<pre><code>&lt;?php

function include_get_params($file) {
 $parts = explode('?', $file);
 if (isset($parts[1])) {
 parse_str($parts[1], $output);
 foreach ($output as $key =&gt; $value) {
 $_GET[$key] = $value;
 }
 }
 include($parts[0]);
}
?&gt;
</code></pre>

The function checks for query params, and automatically adds them to the $_GET variable. This has worked pretty good for my use cases.

Here is an example on the form page when called:

<pre><code>&lt;?php
// We check for a total of 12
for ($i=0; $i&lt;12; $i++) {
 if (isset($_POST['references_name_'.$i]) &amp;&amp; !empty($_POST['references_name_'.$i])) {
 include_get_params(DIR .'references.php?count='. $i);
 } else {
 break;
 }
}
?&gt;
</code></pre>

Just another example of including GET params dynamically to accommodate certain use cases. Hope this helps. Please note this code isn't in its complete state but this should be enough to get anyone started pretty good for their use case.

blocks|key|1485971|text|你也可以使用$GLOBALS来解决这个问题。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1485972|$myvar+=+"Hey";

If anyone else is on this question, when using <code>include('somepath.php');</code> and that file contains a function, the var must be declared there as well. The inclusion of <code>$var=$var;</code> won't always work. Try running these:

one.php: 

<pre><code>&lt;?php
 $vars = array('stack','exchange','.com');

 include('two.php'); /*----- "paste" contents of two.php */

 testFunction(); /*----- execute imported function */
?&gt;
</code></pre>

two.php:

<pre><code>&lt;?php
 function testFunction(){ 
 global $vars; /*----- vars declared inside func! */
 echo $vars[0].$vars[1].$vars[2];
 }

I have to show a page from my php script based on certain conditions. I have an if condition and am doing an "include" if the condition is satisfied.

<pre><code>if(condition here){
 include "myFile.php?id='$someVar'";
}

Now the problem is the server has a file "myFile.php" but I want to make a call to this file with an argument (id) and the value of "id" will change with each call.

Can someone please tell me how to achieve this?
Thanks.

PHP - include a php file and also send query parameters

服务器

我必须显示一个页面从我的php脚本基于某些条件。我有一个if条件，如果条件满足，我将执行一个"include“。if(condition here){  include "myFile.php?id='$someVar'";}现在的问题是服务器有一个文件"myFile.php“，但是我想用一个参数(id)调用这个文件，"id”的值在每次调用时都会改变。有人能告诉我如何做到这一点吗？谢谢。
