$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! |
