I'm using the googleAds API, but when I include a class that I need in my function
it still shows me an error :
Error: Class 'TargetingIdeaSelector' not found
File: C:\wamp64\www\projet\app\Model\Keyword.php
Line: 26
I'm including it like this :
include 'C:\wamp64\www\projet\vendors\googleads\googleads_php_lib\src\Google\AdsApi\AdWords\v201710\o\TargetingIdeaSelector.php';
And further in my function, I'm using this :
// Create selector.
$selector = new TargetingIdeaSelector();
Bringing me the error above.
Is there something else to do to use a class previously included ?
Got a fix from someone better than me :
require_once __DIR__ . '../../Vendor/autoload.php';
use Google\AdsApi\AdWords\v201710\o\TargetingIdeaSelector;
use Google\AdsApi\AdWords\v201710\o\LanguageSearchParameter;
use Google\AdsApi\AdWords\v201710\o\RelatedToQuerySearchParameter;
use Google\AdsApi\AdWords\v201710\cm\Language;
use Google\AdsApi\AdWords\v201710\cm\Paging;
It was all about using the good namespaces, I just was overloaded by the quantity of files in my project and couldn't figure out the solution out of my mess.
My bad :)

I think this is very simple for many of you, but in the moment I got stuck with this. I have the following part of code:
header.php
include "facebook/autoload.php";
use Facebook\FacebookRedirectLoginHelper;
test.php
include "header.php";
$helper = new FacebookRedirectLoginHelper($redirect_url);
Why do I always get this error:
Fatal error: Class 'FacebookRedirectLoginHelper' not found in test.php on line
I thought when I include a PHP file, classes can also be used. But in this case not, why? I think I do not understand how this autoload and use works, so I would be happy for some explanation.
PHP does not inherit the namespaces nor the use statements of included/required files. This is intentional as otherwise if you include 2 files using a class aliased the same way you will get errors and you might not need all those classes in firs place.
If a class requires a namespace it has to have use statement defined with the full namespace to the particular class they need. Except in the cases where there might be aliasing. For example if you have:
// file1.php
use \My\Cool\LogWriter as Writer;
and
// file2.php
use \My\Cool\FileWriter as Writer;
Now both classes are accessible as Writer.
// test.php
require 'file1.php';
require 'file2.php';
In which case if you don't declare which class from which space you want this will give nasty error that class Writer is defined, which is true, but it is also true that the two classes are 2 separate ones.
For more information on namespaces in PHP5 see (http://php.net/manual/en/language.namespaces.php).
As a side note:
Every file, if not namespace declaration is provided is considered in the global namespace.
If a use is without leading slash the namespace might be considered relative to the current. (unsure but I think it depends on the autoloader?) (Reference here: https://stackoverflow.com/a/4879615/1747193)
This is a sample code:
sample code
I want to call it in another page:
include 'root of class file';
$r = new ImagineResizer();
I got this error:
Fatal error: Class 'ImagineResizer' not found in C:\WampDeveloper\Websites\example.com\webroot\images.php on line 13
Also call the function:
$r->resize('c:/test1.jpg', 'c:/test2.jpg');
As seen in your sample code the class is located in another namespace :
<?php
namespace Acme\MyBundle\Service;
use Symfony\Component\HttpFoundation\File\File;
use Imagine\Image\ImagineInterface;
use Imagine\Image\BoxInterface;
use Imagine\Image\Point;
use Imagine\Image\Box;
class ImagineResizer {
//-- rest of code
}
To use a class in another namespace you need to point out where the file is :
First include the class (manual or with autoloading)
Then u can create an instance in 2 ways. First way with the use-keyword
use Acme\MyBundle\Service\ImageResizer;
$object = new ImageResizer();
Or point to the class absolute :
$object = new \Acme\MyBundle\Service\ImageResizer();
Hopefully, this will help you out some:
Make sure you include the actual file - not just the folder where it lies.
Make sure that the file you're calling the class from uses the same namespace as your class file. If it doesn't, you have to call the class using the full namespace.
Profit.
The namespaces really had my patience go for a spin when I started using them, but once you're used to it it's not too hard. I would recommend using an autoloader though. It's a bit of a hassle to set up, but once it's done it helps out a bunch.

I just wanna use a namespace in another file, to use the class in it, but im too retarded to do this...
first file:
namespace fun;
use fun\kjr\trouble;
$trouble = new trouble('http://someURL');
second file:
namespace fun\kjr;
class trouble { ... }
This is the error i get:
Error: Fatal error: Class 'fun\kjr\trouble' not found in D:\wamp\www\fun\index.php on line 8
Where did I declare a wrong namespace? Oo
Greetings
I had to include my class aswell.
use namespace
only makes the class available in the actual context.
It does NOT include it, so you can cause it.
use
include_once('your.file')
to do that!
Thanks #Michael Berkowski for helping.
The problem (from what I can see) is you haven't specified an autoloader (e.g. with spl_autoload_register()) or haven't included the file in your code. The use statement will only find a class for you if you have an autoloader in place, otherwise you must include your code ahead of time with include/include_once or require/require once.
I would start with making an autoloader and registering it and then it may be wise to map your namespaces to directory structure as specified by PSR-0.
I'm using Elastica search engine for my Symfony project.
Now, I'm getting the below error :
The autoloader expected class "Elastica_Query_Bool" to be defined in
file
"/blablabla/vendor/ruflin/elastica/lib/Elastica/Query/Bool.php".
The file was found but the class was not in it, the class name or
namespace probably has a typo.
If I change new \Elastica_Query_Bool() for new \Elastica\Query\Bool() in my php file, it works fine.
But I can't understand why I'm getting an error now. Any idea ?
Because when you new Elastica_Query_Bool it's looking for a class actually called Elastica_Query_Bool. And of course the actual class is called Bool.
try:
use Elastica\Query\Bool; // At the top of your file following the namespace line.
...
$bool = new Bool();
Might want to review namespaces in the php manual.
I am trying to use the SwiftMailer php library with a program that I wrote. I have been using the spl_autoload_register() function just fine before including this library. However, prior to using this library I was explicitly defining the class extensions and locations using the spl functions:
set_include_path(get_include_path().[my include path]);
spl_autoload_extensions('.class.php');
spl_autoload_register();
session_start();
The problem I'm running into, is that now I'm trying to use a library that does not follow along the same naming conventions. Their own autoload class (built by the initial call to the library) looks like this.
public static function autoload($class)
{
//Don't interfere with other autoloaders
if (0 !== strpos($class, 'Swift_'))
{
return;
}
$path = dirname(__FILE__).'/'.str_replace('_', '/', $class).'.php';
if (!file_exists($path))
{
return;
}
if (self::$initPath && !self::$initialized)
{
self::$initialized = true;
require self::$initPath;
}
require $path;
}
When I try to simply run the program after calling their class I get:
Fatal error: spl_autoload() [<a href='function.spl-autoload'>
function.spl-autoload</a>]:Class Swift_MailTransport could not
be loaded in [my file] on line 30
Line 30:
$transport = Swift_MailTransport::newInstance();
I have tried using a custom autoload class modeled after theirs, however, all I get when I try:
var_dump(spl_autoload_functions());
results:
bool(false);
I know this has to be a fairly simple issue, something that I'm overlooking, but I can't find it.
Any help would be greatly appreciated.
Try removing this:
spl_autoload_register();
From the documentation:
[if] spl_autoload_register() is called without any parameters then
[spl_autoload(...)] functions will be used
Knowing that, it's only logical to think that spl_autoload does not know where to load your SwiftMailer classes because the errors you get say so. It then follows that SwiftMailer is not in your include path because spl_autoload tries to load from there.
Next step is to put your SwiftMailer classes in one of the include paths.
Ok, after knocking my head against the wall all day and getting nowhere, I got a great piece of feedback from my brother who is also a programmer.
The whole problem, stemmed from this one line:
require_once(SITE_ROOT.'/classes/lib/swift_required.php');
The SITE_ROOT variable was actually referencing the web location (i.e. http://), with my current host, this does not work, it needs to use the physical file location instead. After making this change, the included autoloader works as advertised.
