我有一个从数据库返回的用户对象,如下所示：
[
{
"id":1,"name":"Bob","category":"admin","email":"test1@test.com","phone":"123456789","gender":"male",},{
"id":2,"name":"John","category":"user","email":"john@test.com",{
"id":3,"name":"Jane","email":"jane@test.com","gender":"female",]
现在,我想循环遍历所有用户对象,并删除其category属性为user的所有用户,以便生成的用户对象仅保留为admin类别.
我想用foreach循环来做这个.请问我该如何解决这个问题,或者我有什么更好的方法来实现这个目标？
我猜这个数组是JSON格式的吗？无论如何..我修复了你的无效JSON,所以你应该能够看到它是如何完成的.
$json = '
[{
"id": 1,"name": "Bob","category": "admin","email": "test1@test.com","phone": "123456789","gender": "male"
},{
"id": 2,"name": "John","category": "user","email": "john@test.com",{
"id": 3,"name": "Jane","email": "jane@test.com","gender": "female"
}]
';
$array = json_decode($json,true); //Fixed and converted JSON into PHP Assoc Array
foreach($array as $k=>$v) {
foreach ($array[$k] as $key=>$value) {
if ($key === "category" && $value === "user") { //If Value of 2D is equal to user and cat
unset($array[$k]); //Delete from Array
}
}
}
var_dump($array); //Output Array
产量
array(2) {
[0] => array(6) {
["id"] => int(1)["name"] => string(3)
"Bob" ["category"] => string(5)
"admin" ["email"] => string(14)
"test1@test.com" ["phone"] => string(9)
"123456789" ["gender"] => string(4)
"male"
}[2] => array(6) {
["id"] => int(3)["name"] => string(4)
"Jane" ["category"] => string(5)
"admin" ["email"] => string(13)
"jane@test.com" ["phone"] => string(9)
"123456789" ["gender"] => string(6)
"female"
}
}

*正如@sevavietl在评论中指出的那样,如果数组的任何其他元素被称为user,那么这将被删除.我已经将代码更改为现在测试密钥(类别)以及值. *
