[英]Fatal error: Cannot redeclare class Swift Kohana Framework Email Swiftmailer
[英]Kohana: Cannot redeclare class
無法在Kohana開始項目。 我已經從github克隆了它,而不是在配置文件中設置我的數據庫信息並得到錯誤:無法重新聲明類。
我有兩種方法自動加載功能。
public static function auto_load($class, $directory = 'classes')
{
// Transform the class name according to PSR-0
$class = ltrim($class, '\\');
$file = '';
$namespace = '';
if ($last_namespace_position = strripos($class, '\\'))
{
$namespace = substr($class, 0, $last_namespace_position);
$class = substr($class, $last_namespace_position + 1);
$file = str_replace('\\', DIRECTORY_SEPARATOR, $namespace).DIRECTORY_SEPARATOR;
}
$file .= str_replace('_', DIRECTORY_SEPARATOR, $class);
if ($path = Kohana::find_file($directory, $file))
{
// Load the class file
require_once $path;
// Class has been found
return TRUE;
}
// Class is not in the filesystem
return FALSE;
}
/**
* Provides auto-loading support of classes that follow Kohana's old class
* naming conventions.
*
* This is included for compatibility purposes with older modules.
*
* @param string $class Class name
* @param string $directory Directory to load from
* @return boolean
*/
public static function auto_load_lowercase($class, $directory = 'classes')
{
// Transform the class name into a path
$file = str_replace('_', DIRECTORY_SEPARATOR, strtolower($class));
if ($path = Kohana::find_file($directory, $file))
{
// Load the class file
require_once $path;
// Class has been found
return TRUE;
}
// Class is not in the filesystem
return FALSE;
}
我試過在require()之前添加class_exists()但它不起作用我應該怎么做才能啟動一個項目?
可能需要的類已包含在其他文件中。 我不知道你究竟是怎么檢查類碰撞問題的,但你應該做的事情如下:
function include_quietly($file) {
$conflicts = false;
$txt = file_get_contents($file);
preg_match_all("#class\s+(\w+)\s*{#muis", $txt, $matches, PREG_SET_ORDER);
foreach ($matches as $m) {
if (class_exists($m[1])) {
$conflicts = true;
break;
}
}
if (!$conflicts)
include_once $file;
else
echo "include conflicts in file {$file}\n";
}
include_quietly($path);
