It is discouraged to do in a view so there is no blade tag for it.
If you do want to do this in your blade view, you can either just open a php tag as you wrote it or register a new blade tag. Just an example:

In <a href="/questions/tagged/laravel-4" class="post-tag" title="show questions tagged 'laravel-4'" rel="tag">laravel-4</a>, you can use the template comment syntax to define/set variables.

Comment syntax is <code>{{-- anything here is comment --}}</code> and it is rendered by <a href="/questions/tagged/blade" class="post-tag" title="show questions tagged 'blade'" rel="tag">blade</a> engine as

<code>&lt;?php /* anything here is comment */ ?&gt;</code>

so with little trick we can use it to define variables, for example

<pre><code>{{-- */$i=0;/* --}}
</code></pre>

will be rendered by <a href="/questions/tagged/blade" class="post-tag" title="show questions tagged 'blade'" rel="tag">blade</a>as 
 <code>&lt;?php /* */$i=0;/* */ ?&gt;</code> which sets the variable for us. 
Without changing any line of code.

I'm going to extend the answer given by @Pim.

Add this to the boot method of your AppServiceProvider

<pre><code>&lt;?php
/*
|--------------------------------------------------------------------------
| Extend blade so we can define a variable
| &lt;code&gt;
| @set(name, value)
| &lt;/code&gt;

*/

Blade::directive('set', function($expression) {
 list($name, $val) = explode(',', $expression);
 return "&lt;?php {$name} = {$val}; ?&gt;";
});
</code></pre>

This way you don't expose the ability to write any php expression.

You can use this directive like:

<pre><code>@set($var, 10)
@set($var2, 'some string')
</code></pre>

We can use <code>&lt;?php ?&gt;</code> tag in blade page

OR

We can use the blade comment with special syntax

Hacking comments is not a very readable way to do it. Also editors will color it as a comment and someone may miss it when looking through the code.

Try something like this:

It will compile into:

<pre><code>&lt;?php echo ''; $hello = 'world'; ?&gt;

...and do the assignment and not echo anything.

In my opinion it would be better to keep the logic in the controller and pass it to the view to use. This can be done one of two ways using the 'View::make' method. I am currently using Laravel 3 but I am pretty sure that it is the same way in Laravel 4.

<pre><code>public function action_hello($userName)
{
 return View::make('hello')-&gt;with('name', $userName);
}
</code></pre>

or

<pre><code>public function action_hello($first, $last)
{
 $data = array(
 'forename' =&gt; $first,
 'surname' =&gt; $last
 );
 return View::make('hello', $data);
}
</code></pre>

The 'with' method is chainable. You would then use the above like so:

<pre><code>&lt;p&gt;Hello {{$name}}&lt;/p&gt;
</code></pre>

I had a similar question and found what I think to be the correct solution with <a href="http://laravel.com/docs/responses#view-composers" rel="nofollow">View Composers</a>

View Composers allow you to set variables every time a certain view is called, and they can be specific views, or entire view templates. Anyway, I know it's not a direct answer to the question (and 2 years too late) but it seems like a more graceful solution than setting variables within a view with blade.

<pre><code>View::composer(array('AdminViewPath', 'LoginView/subview'), function($view) {
 $view-&gt;with(array('bodyClass' =&gt; 'admin'));
});
</code></pre>

blocks|key|452695|text|laravel+5你可以很容易做到这一点。见下文|type|unstyled|depth|inlineStyleRanges|entityRanges|data|452696|{{--*/+@$variable_name+=+'value'++/*--}}|code-block|syntax|javascript|452697|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

laravel 5 you can easily do this . see below 

<pre><code>{{--*/ @$variable_name = 'value' /*--}}
</code></pre>

blocks|key|234914|text|您可以使用extend方法来扩展刀片，如下所示。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|234915|Blade::extend(function($value)+{
++++return+preg_replace('/\@var(.%2B)/',+'<?php+${1};+?>',+$value);
});|code-block|syntax|javascript|234916|然后初始化变量，如下所示。|234917|@var+$var+=+"var"|234918|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]]|$1|G|3|H|5|6|7|O|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

You can extend blade by using the extend method as shown below..

<pre><code>Blade::extend(function($value) {
 return preg_replace('/\@var(.+)/', '&lt;?php ${1}; ?&gt;', $value);
});
</code></pre>

after that initialize variables as follows.

<pre><code>@var $var = "var"
</code></pre>

blocks|key|234982|text|在刀片文件中，您可以使用以下格式|type|unstyled|depth|inlineStyleRanges|entityRanges|data|234983|@php
++$i%2B%2B
@endphp|code-block|syntax|javascript|234984|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

inside the blade file, you can use this format
<pre><code>@php
 $i++
@endphp
</code></pre>

blocks|key|235025|text|在laravel8中|type|unstyled|depth|inlineStyleRanges|entityRanges|data|235026|@php

+$name="Abdul+mateen";

{{+echo+$name;+}}
++++

In laravel8
<pre><code>@php

 $name=&quot;Abdul mateen&quot;;

{{ echo $name; }}
 
@endphp
</code></pre>

blocks|key|452795|text|适用于所有版本的blade。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|452796|{{--*/++$optionsArray+=+['A',+'B',+'C',+'D','E','F','G','H','J','K']+/*--}}|code-block|syntax|javascript|452797|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

works in all versions of blade.

<pre><code>{{--*/ $optionsArray = ['A', 'B', 'C', 'D','E','F','G','H','J','K'] /*--}}
</code></pre>

I'm reading the Laravel Blade <a href="https://laravel.com/docs/master/blade" rel="noreferrer">documentation</a> and I can't figure out how to assign variables inside a template for use later. I can't do <code>{{ $old_section = "whatever" }}</code> because that will echo "whatever" and I don't want that.

I understand that I can do <code>&lt;?php $old_section = "whatever"; ?&gt;</code>, but that's not elegant.

Is there a better, elegant way to do that in a Blade template?

How to Set Variables in a Laravel Blade Template

服务器

我正在阅读Laravel Blade ，但我不知道如何在模板中分配变量供以后使用。我不能做{{ $old_section = "whatever" }}，因为那会重复“随你便”，我不想那样。我知道我可以做<?php $old_section = "whatever"; ?>，但这并不优雅。在Blade模板中有没有一种更好、更优雅的方式来做到这一点？
