You can just add these code in AppServiceProvider class boot method.

<pre><code>Blade::extend(function($value, $compiler){
 $value = preg_replace('/(\s*)@switch$(.*)$(?=\s)/', '$1&lt;?php switch($2):', $value);
 $value = preg_replace('/(\s*)@endswitch(?=\s)/', '$1endswitch; ?&gt;', $value);
 $value = preg_replace('/(\s*)@case$(.*)$(?=\s)/', '$1case $2: ?&gt;', $value);
 $value = preg_replace('/(?&lt;=\s)@default(?=\s)/', 'default: ?&gt;', $value);
 $value = preg_replace('/(?&lt;=\s)@breakswitch(?=\s)/', '&lt;?php break;', $value);
 return $value;
 });
</code></pre>

then you can use as:

<pre><code>@switch( $item )
 @case( condition_1 )
 // do something
 @breakswitch
 @case( condition_2 )
 // do something else
 @breakswitch
 @default
 // do default behaviour
 @breakswitch
@endswitch
</code></pre>

Enjoy It~

In Laravel 5.1, this works in a Blade:

<pre><code>&lt;?php
 switch( $machine-&gt;disposal ) {
 case 'DISPO': echo 'Send to Property Disposition'; break;
 case 'UNIT': echo 'Send to Unit'; break;
 case 'CASCADE': echo 'Cascade the machine'; break;
 case 'TBD': echo 'To Be Determined (TBD)'; break;
 }
?&gt;
</code></pre>

blocks|key|4598|text|您可以像这样扩展刀片：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4599|++++Blade::directive('switch',+function+($expression)+{

++++});
++++Blade::directive('endswitch',+function+()+{
++++++++return+"<?php+endswitch;+?>";

@endswitch|4602|但是，请注意：http://php.net/manual/en/control-structures.alternative-syntax.php中的警告|offset|length|4603|如果switch()：和第一种情况之间有任何空格，那么整个代码块都将失败。这是PHP的限制，而不是刀片的限制。您可以通过强制使用常规语法来绕过它，例如：|4604|Blade::directive('switch',+function+($expression)+{

});
Blade::directive('endswitch',+function+($)+{

You can extend blade like so:

<pre><code> Blade::directive('switch', function ($expression) {
 return "&lt;?php switch($expression): ?&gt;";
 });
 Blade::directive('case', function ($expression) {
 return "&lt;?php case $expression: ?&gt;";
 });
 Blade::directive('break', function () {
 return "&lt;?php break; ?&gt;";
 });
 Blade::directive('default', function () {
 return "&lt;?php default: ?&gt;";
 });
 Blade::directive('endswitch', function () {
 return "&lt;?php endswitch; ?&gt;";
 });
</code></pre>

You can then use the following:

<pre><code>@switch($test)
@case(1)
 Words
@break
@case(2)
 Other Words
 @break
@default
 Default words
@endswitch
</code></pre>

However do note the warnings in : <a href="http://php.net/manual/en/control-structures.alternative-syntax.php" rel="nofollow noreferrer">http://php.net/manual/en/control-structures.alternative-syntax.php</a>

If there is any whitespace between the switch(): and the first case then the whole code block will fail. That is a PHP limitation rather than a blade limitation. You may be able to bypass it by forcing the normal syntax e.g.:

<pre><code>Blade::directive('switch', function ($expression) {
 return "&lt;?php switch($expression) { ?&gt;";
});
Blade::directive('endswitch', function ($) {
 return "&lt;?php } ?&gt;";
});
</code></pre>

But this feels a bit wrong.

blocks|key|4678|text|这有点离题，但由于某些原因，如果‘@case("foo")’是字符串，使用双引号作为@case("foo")不能像预期的那样工作，如果你遇到这样的问题，单引号似乎可以工作，所以用@case('foo')代替case。也许有更多信息的人可能会对此有所了解。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|4679|致以问候。|4680|entityMap^0|H|C|16|C|2H|C|0|0^^$0|@$1|2|3|4|5|6|7|J|8|@$9|K|A|L|B|C]|$9|M|A|N|B|C]|$9|O|A|P|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|Q|8|@]|D|@]|E|$]]|$1|H|3|-4|5|6|7|R|8|@]|D|@]|E|$]]]|I|$]]

It's a bit off-topic but for some reason, if the 'cases' are strings, using double quotes as such <code>@case(&quot;foo&quot;)</code> is not working as expected, in case you're experiencing such a problem, single quotes seem to work, so instead of <code>@case(&quot;foo&quot;)</code> use <code>@case('foo')</code>. Maybe someone with more information could shed some light on this.

blocks|key|4512198|text|要克服'switch+()‘中的空格，您可以使用代码：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4512199|Blade::extend(function($value,+$compiler){

To overcome the space in 'switch ()', you can use code :

<pre><code>Blade::extend(function($value, $compiler){
 $value = preg_replace('/(\s*)@switch[ ]*$(.*)$(?=\s)/', '$1&lt;?php switch($2):', $value);
 $value = preg_replace('/(\s*)@endswitch(?=\s)/', '$1endswitch; ?&gt;', $value);
 $value = preg_replace('/(\s*)@case[ ]*$(.*)$(?=\s)/', '$1case $2: ?&gt;', $value);
 $value = preg_replace('/(?&lt;=\s)@default(?=\s)/', 'default: ?&gt;', $value);
 $value = preg_replace('/(?&lt;=\s)@breakswitch(?=\s)/', '&lt;?php break;', $value);
 return $value;
 });
</code></pre>

blocks|key|4509|text|当您开始在视图中使用switch语句时，这通常意味着您可以进一步重构您的代码。业务逻辑不是用于视图的，我建议您在控制器中执行switch语句，然后将switch语句的结果传递给视图。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4510|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|$]]

When you start using switch statements within your views, that usually indicate that you can further re-factor your code. Business logic is not meant for views, I would rather suggest you to do the switch statement within your controller and then pass the switch statements outcome to the view.

How can I use switch in blade templates? When I used:

<pre><code>@switch($login_error)
 @case(1)
 `E-mail` input is empty!
 @break
 @case(2)
 `Password` input is empty!
 @break
@endswitch
</code></pre>

in result I see this text as plaintext. I prefer to use switch in few piece of code because it's more clean for me than when I using if.

But if it's not possible just write it.
