下面提供两款高效的经典的删除数组元素的方法,我们可以指定删除那个就删除,有需要的同学可以参考一下,这里来自php.net哦。  

 代码如下 复制代码

function deleteFromArray(&$array, $deleteIt, $useOldKeys = FALSE)
{
    $tmpArray = array();
    $found = FALSE;
    foreach($array as $key => $value)
    {
        if($value !== $deleteIt)
        {
            if(FALSE === $useOldKeys)
            {
                $tmpArray[] = $value;
            }
            else
            {
                $tmpArray[$key] = $value;
            }
        }
        else
        {
            $found = TRUE;
        }
    }
  
    $array = $tmpArray;
  
    return $found;
}
?>
