Check if a value exits in array (Laravel or Php)
提问by Funny Frontend
I have this array:
我有这个数组：
$list_desings_ids = array('hc1wXBL7zCsdfMu','dhdsfHddfD','otheridshere');
With a die() + var_dumo() this array return me:
使用 die() + var_dumo() 这个数组返回我：
array:2 [▼
0 => "hc1wXBL7zCsdfMu"
1 => "dhdsfHddfD"
2 => "otheridshere"
]
I want check if a design_id exits in $list_desings_ids array.
我想检查 $list_desings_ids 数组中是否存在 design_id 。
For example:
例如：
foreach($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;
}
But this not works to me, what is the correct way?
但这对我不起作用，正确的方法是什么？

You can use in_arrayfor this.
您可以in_array为此使用。
Try
尝试
$design_id = 'hc1wXBL7zCsdfMu';
$list_desings_ids = array('hc1wXBL7zCsdfMu','dhdsfHddfD','otheridshere');
if(in_array($design_id, $list_desings_ids))
{
echo "Yes, design_id: $design_id exits in array";
}

instead array_key_existsyou just type in_arraythis will solve your issue
because if you dump your this array
相反，array_key_exists您只需键入in_array这将解决您的问题，因为如果您转储此数组
$list_desings_ids = array('hc1wXBL7zCsdfMu','dhdsfHddfD','otheridshere');
output will be,
输出将是，
array(
0 => hc1wXBL7zCsdfMu,
1 => dhdsfHddfD,
2 => otheridshere
)
so your code array_key_existswill not work, because here in keys 0,1,2exists, So, you want to check values,so for values, just do this in_arrayit will search for your desire value in your mentioned/created array
所以你的代码array_key_exists将不起作用，因为这里0,1,2存在键，所以，你想检查值，所以对于值，只要这样做，in_array它就会在你提到/创建的数组中搜索你想要的值

Your array not have key .
try this
您的阵列没有 key 。
尝试这个
foreach($general_list_designs as $key_design=>$design) {
#$desing->desing_id return me for example: hc1wXBL7zCsdfMu
if(in_array($design->design_id, $list_desings_ids))
$final_designs[] = $design;
}

you need to change only your condition replace with that code
您只需要更改您的条件替换为该代码
if(in_array($design->design_id, $list_desings_ids))
