如何 implode 和 foreach get

Question

我尝试获取每个“名称”并将其发送到我的数据库进行验证问题是我不能把每一个都拿走并通过 foreach

$name = $this->UserSkills->where('id', session()->get('id'))->first();
print_r($name) // return Array ( 
                          [id] => 5 
                          [user] => 15 
                          [name] => name,name1,name2,name3,name4
                         )

$name = implode(",", $name['name']);

foreach($name as $row) {
    $setname[] = $this->checkName->getIDbyName($row['name']);
}

$setname = implode(",", $setname);

$data['id_name'] = $setname;

终于要他回来了

echo $data['id_name'] // return: 1,4,8,367, etc...

Answer 1

你第一次使用 implode 是不正确的，你需要 explode 把一个字符串做成一个数组。

<?php

$name = $this->UserSkills->where('id', session()->get('id'))->first();

$name = explode(",", $name['name']);

foreach($name as $row) {
    $setname[] = $this->checkName->getIDbyName($row);
}

$setname = implode(",", $setname);

$data['id_name'] = $setname;

Answer 2

我认为你的 $name['name'] return 是 string 而不是 array，所以你需要 explode() 而不是 implode().

尝试这样的事情：

$name = $this->UserSkills->where('id', session()->get('id'))->first();
print_r($name); // return Array ([id] => 5, [user] => 15, [name] => name,name1,name2,name3,name4)

$names = explode(',', $name['name']); // return Array (0 => name, 1 => name1, 2 => name2, 3 => name3, 4 => name4)

foreach ($names as $row) {
    $setname[] = $this->checkName->getIDbyName($row['name']);
}

$setname = implode(",", $setname); // return 1,4,8,367, etc
$data['id_name'] = $setname; // return 1,4,8,367, etc

echo $data['id_name']; // return 1,4,8,367, etc

假设您的 getIDbyName() return ID 为 integer
