php foreach help

Question

I have a dataset with 4 rows. I am using 2 foreach loops to get my data out. The outer foreach needs to loop once and I need the inner loop to loop 4x. Is there a way to do this or do I need to split the array?

  foreach($reports as $key=>$val)
  {
      if($val['rpt_type'] == 'Sooa')
      {
        foreach($val as $foo)
        {
          echo $foo['name'];
        }
      }
  }

Answer 1

I'm still unsure about how your data structure looks. To me, to be able to utilize a "rpt_type", it would have to look something like this:

$reports = array(
    0 => array(
        'rpt_type' => '...',
        ...
        'rows' => array(
            'name' => '...',
            ...
        ),
    ),
    1 => ...
);

You could then iterate over it with:

foreach($reports as $report) {
    if($report['rpt_type'] == 'Sooa') {
        foreach($report['rows'] as $row) {
            echo $row['name'];
        }
    }
}

Answer 2

First, check the contents of your $reports variable, using var_dump function of php:

var_dump($reports);

It'll print something like this:

array(3) {
  [0]=>
  int(1)
  [1]=>
  int(2)
  [2]=>
  array(3) {
    [0]=>
    string(1) "a"
    [1]=>
    string(1) "b"
    [2]=>
    string(1) "c"
  }
}

Then you can implement your loop looking at the actual data you have, in whichever way your jagged arrays are formed.
