Note: this answer was given for Laravel 4.2, but should still apply. There are some special cases of Blade compilation issues that are dependent on the version of Laravel and/or PHP, so it's best to only use Blade comments for the simplest use-cases. 

The solution is to only use Blade comments for simple remarks, or to comment out single-line Blade functions. Do not nest Blade/PHP code inside of Blade comments. Use standard PHP block comments to comment out multiple lines of code within a single comment (PHP, HTML, multiple blade functions, etc.).

<hr>

Valid Blade Comments:

Single Blade Function:

<pre><code>{{-- Form::text('foo') --}}
</code></pre>

Remark:

<pre><code>{{-- Form Section 1 --}}
</code></pre>

<hr>

Invalid Blade Comments:

Incorrect syntax:

<pre><code>{{-- Form::text('foo') -- }} 
</code></pre>

"@" Inside of Blade comment

<pre><code>{{-- @Form::text('foo') --}} 
</code></pre>

Nested PHP:

<pre><code>{{-- &lt;?php 
echo "foo";
echo "bar
?&gt; --}} 
</code></pre>

Nested Blade:

<pre><code>{{-- 
{{ HTML::form("foo") }};
{{ HTML::form("bar") }};
--}} 
</code></pre>

<hr>

Use PHP Block Comments instead. They are still usable in a blade.php file

<pre><code>&lt;?php /* 
{{ HTML::form("foo") }};
{{ HTML::form("bar") }};
*/ ?&gt; 
</code></pre>

<hr>

Alternatively, comment out your Blade one line at a time:

<pre><code>{{-- HTML::form("foo") --}};
{{-- HTML::form("bar") --}};
</code></pre>

<hr>

Internals:

For the OP's code, Laravel's Blade Compiler will generate a temporary PHP file containing the following PHP/HTML:

<pre><code>&lt;?php /* 
 &lt;div class="form-row"&gt;
 &lt;?php echo Form::label('foo', 'foo:'); ?&gt;

&lt;?php echo Form::text('foo'); ?&gt;

&lt;/div&gt;
&lt;div class="form-row"&gt;
 &lt;?php echo Form::label('foo', 'foo:'); ?&gt;

 &lt;?php echo Form::text('foo'); ?&gt;

&lt;/div&gt;
&lt;div class="form-row"&gt;
 &lt;?php echo Form::label('foo', 'foo'); ?&gt;

 &lt;?php echo Form::text('foo'); ?&gt;

&lt;/div&gt;
*/ ?&gt;
</code></pre>

The Blade inside of your Blade comments are still being parsed into PHP. The PHP end tags inside of the PHP block-comment is causing the Apache's parser to end early, resulting in some badly-formed PHP/HTML that could be crashing your connection (likely caused by the dangling <code>*/ ?&gt;</code>). 

<blockquote>
 <a href="http://php.net/manual/en/language.basic-syntax.comments.php">?> breaks out of PHP mode and returns to HTML mode, and // or #
 cannot influence that.</a>
</blockquote>

Using any of the aforementioned invalid Blade comments will cause similar compilation issues. Avoid Blade comments for anything other than remarks or commenting Blade functions out one line at a time.

entityMap|blocks|key|1bgvh|text|像这样的刀片评论，在我的案例中就是问题所在：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|6karo|{{--++++
++++@if+($test)
++++++++something
++++@else
++++++++something+else
++++@endif
--}}|code-block|syntax|javascript^0|0^^$0|$]|1|@$2|3|4|5|6|7|8|H|9|@]|A|@]|B|$]]|$2|C|4|D|6|E|8|I|9|@]|A|@]|B|$F|G]]]]

Blade comments like this one, were the problem in my case:

<pre><code>{{-- 
 @if ($test)
 &lt;div&gt;something&lt;/div&gt;
 @else
 &lt;div&gt;something else&lt;/div&gt;
 @endif
--}}
</code></pre>

entityMap|blocks|key|1g190|text|我也有类似的症状，似乎只与评论的长度有关。我用一个根本不包含任何PHP代码或blade语句的注释对其进行了测试：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1s7i8|{{--
0123456789abcdef
0123456789abcdef
0123456789abcdef
--}}|code-block|syntax|javascript|257k2|我不断添加重复行的副本，直到它崩溃。这条评论后面跟着一个刀片|ar11r|语句，并且相应的未在编译后的模板中结束，|6f324|但是结案陈词做到了|dvdo2|，导致语法上无效的编译模板。|fb0aq|这似乎是刀片编译器中的一个错误，我将报告它。|3nh93|解决方法是使用--}}{{--+]拆分长刀片注释。^0|0|0|0|0|0|0|0^^$0|$]|1|@$2|3|4|5|6|7|8|T|9|@]|A|@]|B|$]]|$2|C|4|D|6|E|8|U|9|@]|A|@]|B|$F|G]]|$2|H|4|I|6|7|8|V|9|@]|A|@]|B|$]]|$2|J|4|K|6|7|8|W|9|@]|A|@]|B|$]]|$2|L|4|M|6|7|8|X|9|@]|A|@]|B|$]]|$2|N|4|O|6|7|8|Y|9|@]|A|@]|B|$]]|$2|P|4|Q|6|7|8|Z|9|@]|A|@]|B|$]]|$2|R|4|S|6|7|8|10|9|@]|A|@]|B|$]]]]

I have a similar symptom and it seems to be related to the length of the comment alone. I tested it with a comment that doesn't contain any PHP code or blade statements at all:

<pre><code>{{--
0123456789abcdef
0123456789abcdef
0123456789abcdef
--}}
</code></pre>

I kept adding copies of the repeated line until it crashed. The comment was lexically followed by a blade <code>@if</code> statement, and the corresponding <code>&lt;php if(...): ?&gt;</code> did not end up in the compiled template, but the closing <code>&lt;?php endif; ?&gt;</code> did, resulting in a syntactically invalid compiled template.

It seems to be a bug in the blade compiler and I will report it.

The workaround is to split long blade comments with --}}{{--.

entityMap|blocks|key|coium|text|我在laravel+5.1和PHP+7(新的宅基地)上也遇到了同样的问题。解决方法是使用以下代码：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|c26uh|而不是这样：|3gpfk|{{--+XXX+--+}}.|code-block|syntax|javascript^0|0|0^^$0|$]|1|@$2|3|4|5|6|7|8|J|9|@]|A|@]|B|$]]|$2|C|4|D|6|7|8|K|9|@]|A|@]|B|$]]|$2|E|4|F|6|G|8|L|9|@]|A|@]|B|$H|I]]]]

I have same problem with laravel 5.1 and PHP 7 (new homestead). The work around was to use this:

Try this

Comments in Blade are very simple!

I'm rendering a page that is primarily a form with <code>view::make</code> in Laravel and it is crashing, causing ERR_CONNECTION_RESET. After a long investigation and many red herrings, I started erasing (not commenting) random sections out of the blade file for the view and realized that if I 

a) erase 2 of the <code>{{Form}}</code> calls inside this section of the form 

b) remove the <code>{{-- and --}}</code> from around this section of the form

<pre><code> {{--
 &lt;div class="form-row"&gt;
 {{ Form::label('foo', 'foo:') }}
 {{ Form::text('foo') }}
 &lt;/div&gt;
 &lt;div class="form-row"&gt;
 {{ Form::label('foo', 'foo:') }}
 {{ Form::text('foo') }}
 &lt;/div&gt;
 &lt;div class="form-row"&gt;
 {{ Form::label('foo', 'foo') }}
 {{ Form::text('foo') }}
 &lt;/div&gt;
 --}}
</code></pre>

the page will render. I am not sure what exactly the cause here is. There are other blocks above and below, although this is a 3-div commented out section which none of the others are.

Anyone have a clue what is causing this? Running on WAMP if that matters.
