我想從$ employee_salary數(shù)組中的$ employee數(shù)組中添加薪水關鍵字，這兩個數(shù)組都是關聯(lián)的，并且salary僅根據(jù)索引添加到薪水。存在一些未定義偏移量的錯誤。我無法識別問題。這些錯誤就像未定義的偏移量一樣，這會是什么問題？ $employee = array(0=> array("employee_id"=>1, "firstName"=>"Zahir", "lastName"=>"Alam", "Age"=>25, "Company"=>"Switchme", "Role"=>"Developer", "Department"=>"Tech" ,"Head"=> array("Id"=>3 , "Name"=>"Sourasis Roy") ),1=> array("employee_id"=>2, "firstName"=>"Amith", "lastName"=>"Manniken", "Age"=>25, "Company"=>"Switchme", "Role"=>"Developer", "Department"=>"Tech" ,"Head"=> array("Id"=>3 , "Name"=>"Sourasis Roy") ),2=> array("employee_id"=>3, "firstName"=>"Sourasis", "lastName"=>"Roy", "Age"=>28, "Company"=>"Switchme", "Role"=>"CTO"),3=> array("employee_id"=>4, "firstName"=>"Aditya", "lastName"=>"Mishra", "Age"=>29, "Company"=>"Switchme", "Department"=>"Tech", "Role"=>"CEO"),4=> array("employee_id"=>5, "firstName"=>"Priti", "lastName"=>"Lata", "Age"=>24, "Company"=>"Switchme", "Role"=>"HR"),5=> array("employee_id"=>6, "firstName"=>"Sumita", "lastName"=>"Nath", "Age"=>24, "Company"=>"Switchme", "Role"=>"HLA Head", "Department"=>"Crm"),6=> array("employee_id"=>7, "firstName"=>"Tarini", "lastName"=>"Khanna", "Age"=>22, "Company"=>"Switchme", "Role"=>"Content Writer"),7=> array("employee_id"=>8, "firstName"=>"Abhisek", "lastName"=>"Soni", "Age"=>23, "Company"=>"Switchme", "Role"=>"HLA", "Department"=>"Crm","Head"=>array("Id"=>5 , "Name"=>"Sumita Nath") ),8=> array("employee_id"=>9, "firstName"=>"Ankit", "lastName"=>"Pump", "Age"=>23, "Company"=>"Switchme", "Role"=>"HLA", "Department"=>"Crm" ,"Head"=> array("Id"=>5 , "Name"=>"Sumita Nath") ),9=> array("employee_id"=>10, "firstName"=>"Pogo", "lastName"=>"Laal", "Age"=>23, "Company"=>"Switchme", "Role"=>"Designer"),10=> array("employee_id"=>11, "firstName"=>"Sabina", "lastName"=>"Sekh", "Age"=>28, "Company"=>"Switchme", "Role"=>"HLA Head", "Department"=>"Crm"),

如果您可以注意到，兩者$employee[$j]和$employee_salary[$j]都是數(shù)組，那么您不應該等同于它們之間的比較。另外，$employee和$employee_salary數(shù)組的大小都不相同，這就是為什么在循環(huán)中遇到未定義的索引錯誤的原因。$employee_salary[$j]for
將嵌套foreach循環(huán)與引用一起使用以實現(xiàn)所需的結果，如下所示：
foreach($employee as &$emp1){
foreach($employee_salary as $emp2){
if($emp1['employee_id'] == $emp2['employee_id']){
$emp1['salary'] = $emp2['salary'];
}
}
}
// Display complete array structure of $employee
var_dump($employee);

您可以簡單地使用 array_walk
$emp_s = array_column($employee_salary, 'salary','employee_id');
array_walk($employee, function(&$v, $k) use ($emp_s){
if(array_key_exists($k, $emp_s)){
$v['salary'] = $emp_s[$k];
}
});
或者
$temp = array_column($employee_salary, 'salary','employee_id');
array_walk($employee, function(&$v, $k) use ($temp){
$v['salary'] = array_key_exists($k, $temp) ? $temp[$k] : null;
});
