(
[0] => Array
(
[id] => 6
[work_log_id] => 7
[remark] => 测试
)

[1] => Array
(
[id] => 10
[work_log_id] => 8
[remark] => 组长、表格做的好、规则理解的通透，审核帖子误操作少，请假少，群活跃度强、负责任
)

[2] => Array
(
[id] => 7
[work_log_id] => 9
[remark] => 因30分钟漏删三条辞退
)

[3] => Array
(
[id] => 8
[work_log_id] => 10
[remark] => 错漏太多
)

[4] => Array
(
[id] => 11
[work_log_id] => 11
[remark] => 管理自查出错漏
)

[5] => Array
(

[work_log_id] => 11
[remark] => 管理自查出错漏
)

[6] => Array
(

)

[7] => Array

是这样的一个数组，我想取出work_log_id相同的remark值 应该怎么取呢求教各位大佬。

创建个二维数组 第一维度下标是 work_log_id 值是 个数组； 然后遍历你给的这个数组将 每个子array的 remark添加到新的数组下标为当前work_log_id的数组里

[xuzuning]

foreach($arr as $v) $res[$v['work_log_id'][] = $v['remark'];

[一生小白]

$res = [];
foreach($arr as $v) $res[$v['work_log_id'][] = $v['remark'];
