php multi dimensional foreach loop

Question

I have an array and I am trying to loop over it with foreach but I am getting the

Invalid argument supplied for foreach() on the inner loop.

I am not sure what I have incorrect. I have tried with using $key

Here is the array:

array(3) { ["company_id"]=> string(3) "159" 
    [0]=> array(9) { 
        ["company_id"]=> string(3) "159" 
        ["employee_id"]=> string(3) "544" 
        ["pay_week1"]=> string(1) "0" } 
    [1]=> array(9) { 
        ["company_id"]=> string(3) "159" 
        ["employee_id"]=> string(3) "545"  } }

My loop:

foreach ($this->request->data['MonthlyReturn'] as $key=>$m) // Cycle through each record

{
    foreach ($key as $empl)

    {
        $employee = $empl['employee_id'];
        print '<pre>';
        print_r ($employee);
        exit;
    }

You foreach the key of an array value. That is not going to work. Foreach the value ($m) — s.lenders

In inner foreach you are looping $key Change it to $m
Also your first value of the arrays is not a array ie ["company_id"]=> string(3) "159" is a string (159) so it will give error. so before inner foreach check for array also if(is_array($m)){.

Here is the code :

         foreach ($this->request->data['MonthlyReturn'] as $key=>$m){
              if(is_array($m)){
                  echo $m['employee_id'];
              }
              else{
                   echo $m;
              }
         }

I like how you copied his horrible indentation

I am using cakephp so it is setting ["company_id"]=> string(3) if it is a string can I still get the values out?

Prasanth Bendra Over a year ago

Yes.. check my answer ... else condition of is_array

Keith Power Over a year ago

all I get each time is $m being echoed out. I have no control over the array is outputted, is there a way to still get the employee_id?

@KeithPower : If you want only employee_id, you dont want the inner loop, see the edited answer

change this

foreach ($key as $empl)  // $key is array key

to

foreach ($m as $empl)   // $m is your array value

Your array is not going to work on that code. It expects a multidementional array but it isn't completely There is a string value on the first depth

array(3) {
        ["company_id"]=> string(3) "159" <--- problem
        [0]=> array(9) { 
            ["company_id"]=> string(3) "159" 
            ["employee_id"]=> string(3) "544" 
            ["pay_week1"]=> string(1) "0" 
        } 
        [1]=> array(9) { 
            ["company_id"]=> string(3) "159" 
            ["employee_id"]=> string(3) "545"  
        } 
    }

It tries to loop through a string value, which is generating an error
