php - 检查数组中是否存在一个值(Laravel 或 Php)

Question

我有这个数组:

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

用 die() + var_dump() 这个数组返回我:

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

我想检查 $list_desings_ids 数组中是否存在 design_id。

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？

Answer 1

为此，您可以使用 in_array。

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";

}
