各位好，我在程序中用到了websocket功能，程序本机调试没有报错，但是传到服务就报错了，在网上找了下，说是PHP版一本http://s.yanghao.org/program/viewdetail.php?i=140457
我机器上的PHP版本是5.4的，服务器上的是5.2的，请问PHP5.2中有没有方便取代php5.3的命名空间功能，非常急！
require("lib/SplClassLoader.php");
$classLoader = new SplClassLoader("WebSocket","/lib");
$classLoader->register();
$server = new \WebSocket\Server("124.172.243.71", 8000, false);//这里报错
报错的内容如下
Unexpected character in input: '\' (ASCII=92) state=1 in
回复讨论(解决方案)
PHP 在 5.3.0 以后的版本开始支持命名空间。
所以说 你还是乖乖的升级服务器吧
SplClassLoader.php的代码如下，我应该如何改，请各位帮忙！升级服务器非常麻烦，因为服务器还有网站在运行，我没有十分把握，风险太大了，要是网站跑不来起来，那问题就更大了
<?php
class SplClassLoader
{
private $_fileExtension = '.php';
private $_namespace;
private $_includePath;
private $_namespaceSeparator = '\\';
/**
* Creates a new SplClassLoader that loads classes of the
* specified namespace.
*
* @param string $ns The namespace to use.
*/
public function __construct($ns = null, $includePath = null)
{
$this->_namespace = $ns;
$this->_includePath = $includePath;
}
/**
* Sets the namespace separator used by classes in the namespace of this class loader.
*
* @param string $sep The separator to use.
*/
public function setNamespaceSeparator($sep)
{
$this->_namespaceSeparator = $sep;
}
/**
* Gets the namespace seperator used by classes in the namespace of this class loader.
*
* @Return void
*/
public function getNamespaceSeparator()
{
return $this->_namespaceSeparator;
}
/**
* Sets the base include path for all class files in the namespace of this class loader.
*
* @param string $includePath
*/
public function setIncludePath($includePath)
{
$this->_includePath = $includePath;
}
/**
* Gets the base include path for all class files in the namespace of this class loader.
*
* @return string $includePath
*/
public function getIncludePath()
{
return $this->_includePath;
}
/**
* Sets the file extension of class files in the namespace of this class loader.
*
* @param string $fileExtension
*/
public function setFileExtension($fileExtension)
{
$this->_fileExtension = $fileExtension;
}
/**
* Gets the file extension of class files in the namespace of this class loader.
*
* @return string $fileExtension
*/
public function getFileExtension()
{
return $this->_fileExtension;
}
/**
* Installs this class loader on the SPL autoload stack.
*/
public function register()
{
spl_autoload_register(array($this, 'loadClass'));
}
/**
* Uninstalls this class loader from the SPL autoloader stack.
*/
public function unregister()
{
spl_autoload_unregister(array($this, 'loadClass'));
}
/**
* Loads the given class or interface.
*
* @param string $className The name of the class to load.
* @return void
*/
public function loadClass($className)
{
if (null === $this->_namespace || $this->_namespace.$this->_namespaceSeparator === substr($className, 0, strlen($this->_namespace.$this->_namespaceSeparator))) {
$fileName = '';
$namespace = '';
if (false !== ($lastNsPos = strripos($className, $this->_namespaceSeparator))) {
$namespace = substr($className, 0, $lastNsPos);
$className = substr($className, $lastNsPos + 1);
$fileName = str_replace($this->_namespaceSeparator, DIRECTORY_SEPARATOR, $namespace) . DIRECTORY_SEPARATOR;
}
$fileName .= str_replace('_', DIRECTORY_SEPARATOR, $className) . $this->_fileExtension;
require ($this->_includePath !== null ? $this->_includePath . DIRECTORY_SEPARATOR : '') . $fileName;
}
}
}
M，不了解命名空间
搞定了，升级了服务器的PHP版本，升级到5.3就没有问题了
你sb吗，之前说升级怕网站挂掉，现在又升级了，你好像把简单问题复杂化了
