删除空元素的数组方法很多了,我今天来介绍两种经典的方法,一个是利用了array_filter函数,另一个也利用函数调用自定义函数。

 代码如下 复制代码

$str1_array=array('一聚教程网','','http://www.bKjia.c0m','','1654','');
$str1_array=array_filter($str1_array);
print_r($str1_array);
?>

结果


Array
(
[0] => 一聚教程网
[2] => http://www.bKjia.c0m
[4] => 1654
)


实例

 

 代码如下 复制代码

$fangId = PostGet('houseId'); // 取得地址栏值
 $tempArray = array_filter(explode('_',$fangId),"filter"); //以__分成数组并且删除空数组
 
 if( is_array($tempArray) && !empty( $tempArray ) ) //判断数组是否有值
 {
  print_r($tempArray); //测试输出
 }
 else
 {
  MessAge('请选择对比较楼盘','list.php');
 }
 

 function filter($var)  处理函数
 {
   if($var == '')
   {
    return false;
   }
   return true;
 }


测试方法:/compare.php?houseId=2306__2307__2303__2308
