如何检查数组中是否存在数组键?
我需要检查数组中是否存在用户ID,我在下面找到了数组,
Array
(
[0] => Array
(
[user_id] => 1482309797
[week] => 1
[type] => 1
[commission] => 4000
)
[1] => Array
(
[user_id] => 1482309797
[week] => 1
[type] => 1
[commission] => 0
)
[2] => Array
(
[user_id] => 1482309797
[week] => 1
[type] => 1
[commission] => 4000
)
[3] => Array
(
[user_id] => 1482309797
[week] => 1
[type] => 1
[commission] => 0
)
[4] => Array
(
[user_id] => 1483096072
[week] => 1
[type] => 1
[commission] => 4000
)
[5] => Array
(
[user_id] => 1483333245
[week] => 1
[type] => 1
[commission] => 2000
)
)
我想检查用户ID是否存在,我试过下面的代码
foreach ($com_array as $report) {
$user_id=$report['user_id'];
if(array_key_exists($user_id,$output_array)){
echo "Eid found";
}else{
echo "id not found";
}
}
任何一个请帮忙.
最佳答案
foreach ($com_array as $report) {
if(isset($report['user_id'])){
echo "Eid found";
}else{
echo "id not found";
}
}
尝试上面的代码,您将获得输出.
