根据键的重复值从数组中删除行

Question

我有一个名为$data['job_list']的数组，如下所示

Array
(
    [0] => Array
        (
            [job_id] => 2
            [job_title] => JQuery developer
            [job_desc] => Developer
            [job_slug] => 2-JQuery-developer
            [job_type] => 191
            [job_skill] => 2
            [job_salary] => 2
            [job_experience] => 1
            [company_name] => IGUTS
            [company_desc] => IGUTS is a fresh company
            [company_industry] => 24

            [skill_timestamp] => 1397395987
        )

    [2] => Array
        (

            [skill_slug] => 2-JQuery
            [industry] => 24
            [skill_timestamp] => 1397395987
        )

)

[job_id] => 2出现两次

我想要的是，应删除带有重复job_id => 2的行

我怎样才能实现？

Answer 1

$jobIds = array();

foreach ($jobs as $key => $job) {
    if (in_array($jobIds, $job['job_id'])) {
        unset($jobs[$key]);
        continue;
    }
    $jobIds[] = $job['job_id'];
}

print_r($jobs);

Answer 2

我会循环完成每个工作＃34;并创建一个作业ID数组。如果我看到相同的ID两次，那么我会删除副本，并在需要时将其存储在其他地方。

Answer 3

正如Matei Mihai所说，我对他的剧本和宾果游戏做了一些小改动，但它已经解决了。

Matei Mihai在in_array（）函数的参数的数据类型上犯了一个错误

我解决了这个问题。

这是我的代码

    $jobIds = array();

    for($i = 0;$i < count($data['job_list']); $i++ )
    {
        if (in_array($data['job_list'][$i]['job_id'], $jobIds))
            {
                unset($data['job_list'][$i]);
                continue;
            }
        $jobIds[] = $data['job_list'][$i]['job_id'];
    }
