 我试图通过’索引从对象数组中删除对象.这是我到目前为止所得到的,但我很难过. 
  
  
  $index = 2;
$objectarray = array(
0=>array('label'=>'foo','value'=>'n23'),1=>array('label'=>'bar','value'=>'2n13'),2=>array('label'=>'foobar','value'=>'n2314'),3=>array('label'=>'barfoo','value'=>'03n23')
);
//I've tried the following but it removes the entire array.
foreach ($objectarray as $key => $object) {
 if ($key == $index) {
   array_splice($object,$key,1);
   //unset($object[$key]); also removes entire array.
 }
}任何帮助,将不胜感激. 更新方案 array_splice($objectarray,$index,1); //array_splice accepts 3 parameters 
    //(array,start,length) removes the given array and then normalizes the index
    //OR 
    unset($objectarray[$index]); //removes the array at given index
    $reindex = array_values($objectarray); //normalize index
    $objectarray = $reindex; //update variable解决方法array_splice($objectarray,1); 
    //array_splice accepts 3 parameters (array,length) and removes the given 
    //array and then normalizes the index
    //OR 
    unset($objectarray[$index]); //removes the array at given index
    $reindex = array_values($objectarray); //normalize index
    $objectarray = $reindex; //update variable(编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
