I use the pear extension File_PDF in an old PHP app I maintain.
It seems like the last version by that module is version 0.3.3 from and it is not maintained anymore and has been superseded by the package Horde_Pdf from pear.horde.org.
Can I just change the codebase to the new package? Or do I need to change the function calls?
I started a repository where I convert the old code to the new code at https://github.com/rubo77/File_PDF
The old PDF.php was renamed to Writer.php and the fonts are now in another folder. and the class File_PDF was renamed to class Horde_Pdf_Writer.
I replaced the code in my scripts:
and changed
require_once('vendors/pear/File_PDF/PDF.php');
$this->pdf = &File_PDF::factory();
to
require_once('vendors/pear/Horde_Pdf_Writer/Writer.php');
$this->pdf = new Horde_Pdf_Writer();
now I get the error
Uncaught Error: Class 'Horde_String' not found in /var/www/app/vendors/pear/Horde_Pdf_Writer/Writer.php
A better solution would be to use a more actively maintained PDF generation library like TCPDF, which doesn't need much changes either, e.g. from file_PDF to TCPDF just:
replace newLine() with Ln()
replace getOutput() with Output()
SetFont('Arial', ... doesn't work, so just use SetFont('', ...
If you really need this old Library you need to also download those packages:
Horde_Exception
Horde_Util
Horde_Translation
To let it run in a local folder, edit some files:
instead of calling File_PDF with
require_once('vendors/pear/File_PDF/PDF.php');
$this->pdf = &File_PDF::factory();
now call
require_once('vendors/pear/Horde/Pdf/Writer.php');
require_once('vendors/pear/Horde/Pdf/Exception.php');
require_once('vendors/pear/Horde/String.php');
$this->pdf = new Horde_Pdf_Writer();
in Writer.php the function _getFontFile() needs these extra lines:
$fontname = Horde_String::ucfirst(Horde_String::lower($fontkey));
require_once('vendors/pear/Horde/Pdf/Font/'.$fontname.'.php');
$fontClass = 'Horde_Pdf_Font_' . $fontname;
in Exception.php you need to call
require_once('vendors/pear/Horde/Exception/Wrapped.php');
in Wrapped.php you need
require_once('vendors/pear/Horde/Exception.php');

My website is with a hosting provider that has the MessageFormatter class available on the server (Linux, PHP 7.0.27) but it is an old ICU version (4.2.1) that doesn't support my message {number,plural,=0{# available} =1{# available} other{# available}} and gives the error:
Message pattern is invalid: Constructor failed
msgfmt_create: message formatter creation failed: U_ILLEGAL_CHARACTER
...because of the =1 and =2 notation.
I'm not able to make changes to the server so how can I force using the fallback method provided by Yii2 which works just fine?
There is this hacky way you can try.
Copy the yii\i18n\MessageFormatter code to a new file. Name it MessageFormatter.php and place somewhere in your application (but not in vendor folder).
In this new file change the format() method to:
public function format($pattern, $params, $language)
{
$this->_errorCode = 0;
$this->_errorMessage = '';
if ($params === []) {
return $pattern;
}
return $this->fallbackFormat($pattern, $params, $language);
}
Don't change anything else (including namespace).
Now let's use Yii mapping.
Find a place in your application when you can put code that will be run every time in bootstrapping phase. Good place for this is common/config/bootstrap.php if you are using "Advanced Template"-like project.
Add there this line:
Yii::$classMap['yii\i18n\MessageFormatter'] = 'path/to/your/MessageFormatter.php';
Obviously change the path to the one you've chosen. Now Yii autoloader will load this class from your file instead of the original Yii vendor folder (as mentioned in Class Autoloading section of the Guide).
In the modified file MessageFormatter method presence of intl library is never checked so fallback is used as default.
The downside of this trick is that you need to update manually your file every time original Yii file is changed (so almost every time you upgrade Yii version).
Another approach is to configure I18N component in your application to use your custom MessageFormatter where you can extend the original file and just override format() method inside without modifying class map.
i'm want to creating a design pattern and use the "Blade templating engine".
Can I use the Blade templating engine outside of Laravel and use it in my new pattern ?
For the record:
I tested many libraries to run blade outside Laravel (that i don't use) and most are poor hacks of the original library that simply copied and pasted the code and removed some dependencies yet it retains a lot of dependencies of Laravel.
So I created (for a project) an alternative for blade that its free (MIT license, i.e. close source/private code is OK) in a single file and without a single dependency of an external library. You could download the class and start using it, or you could install via composer.
https://github.com/EFTEC/BladeOne
https://packagist.org/packages/eftec/bladeone
It's 100% compatible without the Laravel's own features (extensions).
How it works:
<?php
include "lib/BladeOne/BladeOne.php";
use eftec\bladeone;
$views = __DIR__ . '/views'; // folder where is located the templates
$compiledFolder = __DIR__ . '/compiled';
$blade=new bladeone\BladeOne($views,$compiledFolder);
echo $blade->run("Test.hello", ["name" => "hola mundo"]);
?>
Another alternative is to use twig but I tested it and I don't like it. I like the syntax of Laravel that its close to ASP.NET MVC Razor.
Edit: To this date (July 2018), it's practically the only template system that supports the new features of Blade 5.6 without Laravel. ;-)
You certainly can, there are lots of standalone blade options on packagist, as long as you are comfortable with composer then there should be no issue, this one looks pretty interesting due to having a really high percentage of stars compared to downloads.
Be warned though i have not tried it myself, like you i was looking for a standalone option for my own project and came across it, i will be giving it a real good workout though at sometime in the near future,
Matt Stauffer has created a whole repository showing you how you can use various Illuminate components directly outside of Laravel. I would recommend following his example and looking at his source code.
https://github.com/mattstauffer/Torch
Here is the index.php of using Laravel Views outside of Laravel
https://github.com/mattstauffer/Torch/blob/master/components/view/index.php
You can write a custom wrapper around it so that you can call it like Laravel
use Illuminate\Container\Container;
use Illuminate\Events\Dispatcher;
use Illuminate\Filesystem\Filesystem;
use Illuminate\View\Compilers\BladeCompiler;
use Illuminate\View\Engines\CompilerEngine;
use Illuminate\View\Engines\EngineResolver;
use Illuminate\View\Engines\PhpEngine;
use Illuminate\View\Factory;
use Illuminate\View\FileViewFinder;
function view($viewName, $templateData)
{
// Configuration
// Note that you can set several directories where your templates are located
$pathsToTemplates = [__DIR__ . '/templates'];
$pathToCompiledTemplates = __DIR__ . '/compiled';
// Dependencies
$filesystem = new Filesystem;
$eventDispatcher = new Dispatcher(new Container);
// Create View Factory capable of rendering PHP and Blade templates
$viewResolver = new EngineResolver;
$bladeCompiler = new BladeCompiler($filesystem, $pathToCompiledTemplates);
$viewResolver->register('blade', function () use ($bladeCompiler) {
return new CompilerEngine($bladeCompiler);
});
$viewResolver->register('php', function () {
return new PhpEngine;
});
$viewFinder = new FileViewFinder($filesystem, $pathsToTemplates);
$viewFactory = new Factory($viewResolver, $viewFinder, $eventDispatcher);
// Render template
return $viewFactory->make($viewName, $templateData)->render();
}
You can then call this using the following
view('view.name', ['title' => 'Title', 'text' => 'This is text']);
Yes you can use it where ever you like. Just install one of the the many packages available on composer for it.
If you're interested in integrating it with codeigniter I have a blog post here outlining the process.
Following the above steps should make it obvious how to include it into any framework.
I get this error, when using Zend Framework v2.4: Call to undefined method Zend\Mvc\View\Http\ViewManager::getResolver() in /../../../demo/vendor/dino/dompdf-module/src/DOMPDFModule/Mvc/Service/ViewPdfRendererFactory.php on line 39 But there is no getResolver method in viewmanager. I am using zend framework 2.4/
Can you help me to solve this?
This is included in vender.
<?php
use DOMPDFModule\View\Model\PdfModel;
This is controller action
public function generatepdfAction(){
// $pdf1 = new Zendpdf\PdfDocument();
echo "bbb";
$pdf = new PdfModel();
$pdf->setOption('filename', 'monthly-report'); // Triggers PDF download, automatically appends ".pdf"
$pdf->setOption('paperSize', 'a4'); // Defaults to "8x11"
$pdf->setOption('paperOrientation', 'landscape'); // Defaults to "portrait"
// To set view variables
$pdf->setVariables(array(
'message' => 'Hello'
));
return $pdf;
}
It's not a error in your code. This is a known issue as you can see on https://github.com/raykolbe/DOMPDFModule/issues/37
There is also a pull request for that issue. I solved this with creating my own DOMPDFModule with the changes of this commit, because it seems that there won't be an update of DOMPDFModule soon.
Another possibility would be using an older version of zend-mvc, because the issue appears since zend-mvc 2.7. Just use
"zendframework/zend-mvc": "~2.6.3"
in your composer.json and the the DOMPDFModule will work again. But this should be only a temporarily solution if you want to use new features of the Zend Framework and its modules in the future.
I am trying to use highchart in cakephp and have followed the below tutorial and also the stackoverflow post on the subject.
I still get a highchart not found.
I downloaded highchartPHP and placed all the 4 files in Vendor/HighchartsPHP
In the layout, I add the lines with the actual js files in webroot/js
echo $this->Html->script('jquery-1.9.1.min'); // Include jQuery library
echo $this->Html->script('highcharts'); // Include jQuery library
This is my code
<?php
App::import('Vendor', 'HighchartsPHP/Highchart');
class ChartsController extends AppController
{
public function index() {
$chart = new Highchart(); /////////////////Error: Class 'Highchart' not found
$chart->chart = array(
'renderTo' => 'container', // div ID where to render chart
'type' => 'line'
);
$chart->series[0]->name = 'Tokyo';
$chart->series[0]->data = array(7.0, 6.9, 9.5);
$this->set( compact( 'chart' ) );
}
In view file
<?php $chart->printScripts(); ?>
<script type="text/javascript">
<?php echo $chart->render("chart");?>
</script>

Using HighchartsPHP library in CakePHP
I can't find any more instructions about cakePHP setup with highcharts so I am stuck and I get a highchart not found error.
I still have something missing. What has confused me is that highchartPHP doesn't explain how you install it for a MVC version with cakephp.
How to setup highchart so it works in cakephp ?
I got from the download zip button link so it must be v3
https://github.com/ghunti/HighchartsPHP
also Error: Class 'Highchart' not found from the controller as I outlined above
That's what happens when people don't mention version numbers...
...a year later nobody knows what they were talking about anymore. The tutorial and the question are most probably about version 1.x.
https://github.com/ghunti/HighchartsPHP/tree/v1.0
So a quick fix would be to use v1, but I'm not sure if that's a very good idea as it's probably not maintained anymore.
Namespaces and Composer
Look at the source code of version 2.x and 3.x, they are now using namespaces, and so the class cannot be found when not pointing into that namespace properly.
As mentioned on the projects homepage the library should be installed via composer, and with pretty much all those libraries using composer the generated autoloader needs to be used, but this isn't really the place here to explain how to use composer, this is already extensively covered all over the net.
https://getcomposer.org/doc/00-intro.md
Be sure to check out the CakePHP docs on how to use the composer autoloader with CakePHP too:
[...]
If you’re installing any other libraries with Composer, you’ll need to setup the autoloader, and work around an issue in Composer’s autoloader. In your Config/bootstrap.php file add the following:
// Load Composer autoload.
require APP . 'Vendor/autoload.php';
// Remove and re-prepend CakePHP's autoloader as Composer thinks it is the
// most important.
// See: http://goo.gl/kKVJO7
spl_autoload_unregister(array('App', 'load'));
spl_autoload_register(array('App', 'load'), true, true);
http://book.cakephp.org/.../advanced-installation.html#installing-cakephp-with-composer
I'm attempting to implement https://github.com/PHP-FFMpeg/PHP-FFMpeg
I copied the src/FFMpeg folder to my includes folder and made sure my autoloader knows where to find everything.
as a test I made a script that simply does:
$ffmpeg = FFMpeg\FFMpeg::create();
$video = $ffmpeg->open('video.mpg');
I get:
Fatal error: Class 'Doctrine\Common\Cache\ArrayCache' not found in /var/www/php/include/FFMpeg/FFProbe.php on line 203
My question is: does PHP-FFMPeg require Doctrine, because that is not stated in the documentation. What version do I need? Are there other prerequisites?
I could create a new question for this, but I'm not sure if I should. I now have PHP-ffmpeg implemented. I'm using Laravel, however that should be irrelevant for this question. I'm trying to enable progress monitoring. It works, however I need to pass in an ID so I can update the correct key in memcache.
$id = 12345;
$format->on('progress', function ($audio, $format, $percentage) {
//this works perfect, but doesn't tell me which item is being updated
Cache::put("progress", $percentage, .25);
//this does not work as I am unable to pass in $id, if I add it as the 4th argument above it will display the number of threads or something
//Cache::put("{$id}_progress", $percentage, .25);
});
I need clarification on the "on" method. I looked through https://ffmpeg-php.readthedocs.org/en/latest/_static/API/ and was not able to figure out how this method works. Any help would be appreciated.
You should follow the recommended instructions in the README.
Composer is the easiest way to install PHP-FFMpeg dependencies
The "on" method called on the format is an implementation of EventEmitter.
As you can see here : https://ffmpeg-php.readthedocs.org/en/latest/_static/API/FFMpeg/Format/ProgressableInterface.html it extends the EventEmitterInterface of https://github.com/igorw/evenement.
If you're really interested about how it works under the hood, have a look at here :
The progress listener is created here : https://github.com/PHP-FFMpeg/PHP-FFMpeg/blob/master/src/FFMpeg/Format/Audio/DefaultAudio.php#L96 and added at execution here https://github.com/PHP-FFMpeg/PHP-FFMpeg/blob/master/src/FFMpeg/Media/Video.php#L151
This is actually possible because FFMpegDriver extends the Driver provided by https://github.com/alchemy-fr/BinaryDriver
Hope this helps :)
