自己写的兼容低于PHP 5.5版本的array_column()函数,5.5array_column

array_column 用于获取二维数组中的元素(PHP 5.5新增函数),但我们有时候需要在低版本的PHP环境中使用…

if( ! function_exists('array_column'))
{
  function array_column($input, $columnKey, $indexKey = NULL)
  {
    $columnKeyIsNumber = (is_numeric($columnKey)) ? TRUE : FALSE;
    $indexKeyIsNull = (is_null($indexKey)) ? TRUE : FALSE;
    $indexKeyIsNumber = (is_numeric($indexKey)) ? TRUE : FALSE;
    $result = array();

    foreach ((array)$input AS $key => $row)
    { 
      if ($columnKeyIsNumber)
      {
        $tmp = array_slice($row, $columnKey, 1);
        $tmp = (is_array($tmp) && !empty($tmp)) ? current($tmp) : NULL;
      }
      else
      {
        $tmp = isset($row[$columnKey]) ? $row[$columnKey] : NULL;
      }
      if ( ! $indexKeyIsNull)
      {
        if ($indexKeyIsNumber)
        {
          $key = array_slice($row, $indexKey, 1);
          $key = (is_array($key) && ! empty($key)) ? current($key) : NULL;
          $key = is_null($key) ? 0 : $key;
        }
        else
        {
          $key = isset($row[$indexKey]) ? $row[$indexKey] : 0;
        }
      }

      $result[$key] = $tmp;
    }

    return $result;
  }
}

目前apache最新版本是?可以兼容php536与mysql 55117

下面是个在网上找的安装步骤,具体我也没再apache下配置过,
如果不想麻烦可以下个现成的组件,比如PHPnow,集成了apache+php+mysql+Zend Optimizer+eAccelerator需要配置的都集成好了,安装一下就成啦
当然是2003下好啦

 

cms系统怎做到对各个版本php(40或者50)服务器的兼容?

要做到既可以在php4上运行,又可以在php5上运行,你需要有一个版本判断的功能

你可以这样:
if (version_compare( phpversion(), '5', ' include_once( 'php4.php' ) ;//php4的相关配置文件或调用函数
else
include_once( 'php5.php' ) ;//php5的相关文件或调用函数
}
这样在不同的环境下,就可以调用不同的文件,实现你的功能,不过具体要实现要复杂的多。
希望对你有帮助
