installation errors at UBUNTU 16 about imagehash

Looks like an issue with your php installation.

Ok, a workaround resolved.. Now the problem is about use clause position and path, at my projetc/src folder where I run composer require jenssegers/imagehash now I have as ls:

composer.json  composer.lock   sync.php  
vendor
  autoload.php  
  composer 
  jenssegers
       imagehash
          composer.json  README.md  
          src
              ImageHash.php  Implementation.php  Implementations

Them, at my projects folder I run php sync.php ... ERROR

PHP Fatal error: Uncaught Error: Class 'Jenssegers\ImageHash\ImageHash' not found

Ok, fixed the problem with require __DIR__ . '/vendor/autoload.php' ... So the real problem/suggestion is:

if you see as support, I can add or suggest text for "A Dummy's Guide To Install and use imagehash"

That's not really a problem related to this package. When using a package with composer you are assumed to know at least how to include the composer autoloader.

[faizanjaved5]

require __DIR__ . '/vendor/autoload.php';
$hasher = new ImageHash;
$hash = $hasher->hash('img/img1.jpg');
$hash2 = $hasher->hash('img/img2.jpg');
$distance = $hasher->distance($hash1, $hash2);
echo $distance;

this is my code but still iam getting this error

Fatal error: Uncaught Error: Class 'ImageHash' not found

@sppidy Did you install the package?

composer require jenssegers/imagehash

[faizanjaved5]

@wouterds yes i installed it

@sppidy you still need to add a use statement due to namespaces. Add the following code after your require statement.

use ImageHash;

So it will look like this:

require __DIR__ . '/vendor/autoload.php';
use ImageHash;
$hasher = new ImageHash;

Also, most modern IDE's will alert you to this need and offer auto-fill capabilities. I suggest PHPStorm.
