I want to use https://github.com/box/spout library in my Yii project (in one of commands). I'm not using Composer, so I simple downloaded the extension and put in extensions/spout/Box/.
In my config/main.php I've added line
'import' => array(
...
'application.extensions.spout.*'
),
And in my command I've added following lines:
require_once Yii::app()->basePath . '/extensions/spout/Box/Spout/Reader/ReaderFactory.php';
require_once Yii::app()->basePath . '/extensions/spout/Box/Spout/Common/Type.php';
When I'm calling $reader = ReaderFactory::create(Type::CSV); I'm getting following error:
PHP Error[2]: include(ReaderFactory.php): failed to open stream: No such file or directory
in file /srv/yii/YiiBase.php at line 421
#0 /srv/yii/YiiBase.php(421): autoload()

#9 /srv/dev/protected/yiic.php(19): require_once()
#10 /srv/dev/protected/yiic(4): require_once()
What I'm missing? How can I use third party library in my project?
UPDATE
After that tutorial, I've moved spout folder in protected/vendors folder and changed the code following way:
Yii::import('application.vendors.spout.Box.Spout.Reader.*');
Yii::import('application.vendors.spout.Box.Spout.Common.*');
require_once 'ReaderFactory.php';
require_once 'Type.php';
Now I'm getting following error, still no clue why:
PHP Fatal error: Cannot redeclare class Box\Spout\Reader\ReaderFactory in /srv/dev/protected/vendors/spout/B
ox/Spout/Reader/ReaderFactory.php on line 17
If you are using Yii 2.0 and since Spout is PSR4 compliant, you can follow this guide: http://www.yiiframework.com/doc-2.0/guide-structure-extensions.html#installing-extensions-manually
If you are still using Yii 1.1, I am not sure what the best way to autoload your classes is. But you can still use a standard PSR4 autoloader:
Psr4Autoloader.php
namespace Autoloader;
class Psr4Autoloader
{
/**
* An associative array where the key is a namespace prefix and the value
* is an array of base directories for classes in that namespace.
*
* @var array
*/
protected $prefixes = array();
/**
* Register loader with SPL autoloader stack.
*
* @return void
*/
public function register()
{
spl_autoload_register(array($this, 'loadClass'));
}
/**
* Adds a base directory for a namespace prefix.
*
* @param string $prefix The namespace prefix.
* @param string $base_dir A base directory for class files in the
* namespace.
* @param bool $prepend If true, prepend the base directory to the stack
* instead of appending it; this causes it to be searched first rather
* than last.
* @return void
*/
public function addNamespace($prefix, $base_dir, $prepend = false)
{
// normalize namespace prefix
$prefix = trim($prefix, '\\') . '\\';
// normalize the base directory with a trailing separator
$base_dir = rtrim($base_dir, DIRECTORY_SEPARATOR) . '/';
// initialize the namespace prefix array
if (isset($this->prefixes[$prefix]) === false) {
$this->prefixes[$prefix] = array();
}
// retain the base directory for the namespace prefix
if ($prepend) {
array_unshift($this->prefixes[$prefix], $base_dir);
} else {
array_push($this->prefixes[$prefix], $base_dir);
}
}
/**
* Loads the class file for a given class name.
*
* @param string $class The fully-qualified class name.
* @return mixed The mapped file name on success, or boolean false on
* failure.
*/
public function loadClass($class)
{
// the current namespace prefix
$prefix = $class;
// work backwards through the namespace names of the fully-qualified
// class name to find a mapped file name
while (false !== $pos = strrpos($prefix, '\\')) {
// retain the trailing namespace separator in the prefix
$prefix = substr($class, 0, $pos + 1);
// the rest is the relative class name
$relative_class = substr($class, $pos + 1);
// try to load a mapped file for the prefix and relative class
$mapped_file = $this->loadMappedFile($prefix, $relative_class);
if ($mapped_file) {
return $mapped_file;
}
// remove the trailing namespace separator for the next iteration
// of strrpos()
$prefix = rtrim($prefix, '\\');
}
// never found a mapped file
return false;
}
/**
* Load the mapped file for a namespace prefix and relative class.
*
* @param string $prefix The namespace prefix.
* @param string $relative_class The relative class name.
* @return mixed Boolean false if no mapped file can be loaded, or the
* name of the mapped file that was loaded.
*/
protected function loadMappedFile($prefix, $relative_class)
{
// are there any base directories for this namespace prefix?
if (isset($this->prefixes[$prefix]) === false) {
return false;
}
// look through base directories for this namespace prefix
foreach ($this->prefixes[$prefix] as $base_dir) {
// replace the namespace prefix with the base directory,
// replace namespace separators with directory separators
// in the relative class name, append with .php
$file = $base_dir
. str_replace('\\', '/', $relative_class)
. '.php';
// if the mapped file exists, require it
if ($this->requireFile($file)) {
// yes, we're done
return $file;
}
}
// never found it
return false;
}
/**
* If a file exists, require it from the file system.
*
* @param string $file The file to require.
* @return bool True if the file exists, false if not.
*/
protected function requireFile($file)
{
if (file_exists($file)) {
require $file;
return true;
}
return false;
}
}
Then add this code to your root file or wherever you think it's the most appropriate (just make sure the path for "require_once" is correct):
autoload.php
require_once "Psr4Autoloader.php";
$loader = new \Autoloader\Psr4Autoloader;
$loader->register();
$loader->addNamespace('Box\Spout', 'vendor/box/spout/src/Spout');
You should now be able to use Spout!
