检查数组中是否存在值(Laravel或Php) [英] Check if a value exits in array (Laravel or Php)

问题描述

我有这个数组:

$list_desings_ids = array('hc1wXBL7zCsdfMu','dhdsfHddfD','otheridshere');

使用die()+ var_dumo()，此数组返回我:

With a die() + var_dumo() this array return me:

array:2 [▼
  0 => "hc1wXBL7zCsdfMu"
  1 => "dhdsfHddfD"
  2 => "otheridshere"
]

我要检查是否在$ list_desings_ids数组中退出了design_id.

I want check if a design_id exits in $list_desings_ids array.

例如:

foreach($general_list_designs as $key_design=>$design) {
    #$desing->desing_id return me for example: hc1wXBL7zCsdfMu
    if(array_key_exists($design->design_id, $list_desings_ids))
    $final_designs[] = $design;
}

但这对我不起作用，正确的方法是什么?

But this not works to me, what is the correct way?

推荐答案

而不是array_key_exists您只需键入in_array即可解决您的问题 因为如果您转储此数组

instead array_key_exists you just type in_array this will solve your issue because if you dump your this array

$list_desings_ids = array('hc1wXBL7zCsdfMu','dhdsfHddfD','otheridshere');

输出将是

array(
   0 => hc1wXBL7zCsdfMu,
   1 => dhdsfHddfD,
   2 => otheridshere
)

所以您的代码array_key_exists将不起作用，因为这里的键0,1,2存在，所以，您要检查值，以便获取值，只需执行in_array，它将在您提到的内容中搜索您想要的值/创建的数组

so your code array_key_exists will not work, because here in keys 0,1,2 exists, So, you want to check values,so for values, just do this in_array it will search for your desire value in your mentioned/created array
