php 删除空数组 

$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


方法二

function array_to_hashmap(& $arr, $keyField, $valueField = null) 
{ 
$ret = array(); 
if($valueField) { 
foreach ($arr as $row) { 
$ret[$row[$keyField]] = $row[$valueField]; 
} 
} else { 
foreach($arr as $row) { 
$ret[$row[$keyField]] = $row; 
} 
} 
return $ret; 
}
