从对象数组中删除对象的PHP？

Question

for example say i have an object array called $list looks like this:

<(stdClass)#16 (3) {
  ["1"]=>
  <(8) "50504496"
  ["2"]=>
  <(8) "12435374"
  ["3"]=>
  <(8) "12436374"

Im doing a foreach on the object array and removing them if they exist in the database ie

   foreach($list as $l){

    //do the query

    if( it exists){
      //remove from objects: this is where i need help!!
      }
   }

i have the db logic, im just stuck to know how i can remove objects, i was thinking maybe i should create a new object and add them thier. thanks }

Answer 1

Use: unset

foreach($list as $key => $obj){
  if( exists .. ) {
      unset($list[$key]);
  }
}

Answer 2

运行查询，如果返回的行数>0 ，那么您有结果，请使用unset($object->$var)取消设置变量

Answer 3

Try like:

    foreach($list as $li)
    {
        if($li)
        {
            //copy into another array.
        }
    }

i thnk its may simple

Answer 4

Try like: $i=0;

  foreach($list as $li)
  {
      if($li)
      {
          $b[i] = $li;
          $i++;
      }
   }

array '$b' will hold the values in $list which are not null
