file_get_contents(): Peer certificate CN

Are you trying to inline svg files?

Why use asset? its going to produce a URL rather than just a path

So I should just use a path for the inline SVG? Thought the correct way as to use the asset() to generate the full url

The thing is that my laravel app is inside the folder 'private/laravel/' and the index.php is on the folder '/web'

When doing this in blade

{!! file_get_contents('assets/img/icons/chevron-down.svg') !!}

is it getting the file in the resources/assets/img/... or in the public/assets/img/...

I feel like I'm making a huge confusion here.

if you are in-lining the svg then you just need to get its contents. It does not matter if it is internal or external since everything is running in php at this point.

Where are your svg files located?

In relation to laravel's index.php file on server public folder the svg files are on assets/img/icons/

try

{!! file_get_contents(public_path('/assets/img/icons/chevron_down.svg')) !!}

If that don't work, I have used readfile with success

<?php
$basedir = '/your_path_here_to/laravel55up/storage/app/upload';
$imagedir = $_GET['dir'];
$image = $_GET['img'];

$file = $basedir.'/'.$imagedir.'/'.$image;
$fallback = $basedir.'/fallback.gif';
$size = filesize($file); // File size
$length = $size;
//DETERMINE TYPE
$ext = array_pop(explode ('.', $file)); // adjust as needed
$allowed['gif'] = 'image/gif';
$allowed['png'] = 'image/png';
$allowed['jpg'] = 'image/jpeg';
$allowed['jpeg'] = 'image/jpeg';

if(file_exists($file) && $ext != '' && isset($allowed[strToLower($ext)])) {
    $type = $allowed[strToLower($ext)];
} else {
    $file = $fallback;
    $type = 'image/gif';
}

header("Accept-Ranges: bytes");
header("Cache-Control: public");
header('Content-Type: application/octet-stream');
header("Content-Transfer-Encoding: binary");
header("Content-Length: " . $length);
header("Content-Disposition: inline; filename=\"".$image."\";");
header("Last-Modified: " . date('r', filemtime($file)));

ob_clean();
readfile($file);
exit(0);

?> 

File called with an img src tag.

<img src="<?= '/laravel55/pthru.php?dir=imgdogs&img='  . $dog->dogpic; ?>" alt="" class="imgborder"></a>

Just convert to blade.
