How can I loop through this array and get arrays with only similar values. In the example below, I would like to have an array that contains items 2, 3 and 4 because they all have category_parent => 4 in common.

I need to loop through that array so that I get the following result.

<ul>
  <li>0</li>
  <li>1
    <ul>
      <li>2</li>
      <li>3</li>
      <li>4</li>
    </ul>
  </li>
  <li>5</li>
</ul>

Array

What do you mean by "similar values"? Which values? How "close" do the values have to be to each other to be "similar"? –  Jack Maney Feb 9 '12 at 23:51
    
The example is array items 2, 3 and 4 because they all have same category_parent => 4 –  leonel Feb 9 '12 at 23:55
    
Okay, so loop through the array and only pick out those subarrays with category_parent==4. –  Jack Maney Feb 9 '12 at 23:57
    
If you want something different, you're going to have to coherently explain what you want to do rather than give one example and hope that we're mind readers (Hint: we're not) and can divine what you actually want to do. –  Jack Maney Feb 10 '12 at 0:07
    
The problem is, I have to create HTML lists on the fly. so <ul><li>2</li><li>3</li><li>4</li></ul> –  leonel Feb 10 '12 at 0:08

Use array_filter

$filtered = array_filter($original, function ($class) {
    return $class->category_parent === 4;
});

Stored in a new array.

$result = array();

foreach ($array as $element) {
    if($element->category_parent == 4) {
        $result[] = $element;
    }
}

print_r($result);

He needs to check the multidimensional array for common values, not if value == x –  w0rldart Feb 9 '12 at 23:54
    
@w0rldart - OP is either unable or unwilling to elaborate on what he means other than he wants all of the subarrays with the category_parent value to equal 4. –  Jack Maney Feb 9 '12 at 23:58
    
I'm answering his specific need to filter the category_parent :) –  Muhammad Abrar Feb 10 '12 at 0:00

foreach ($array as $key => $element){
  if ($element->category_parent == 4)
    $ret[] = $key;
}
//$ret is the final array

sorry that saves the indexes not the items. if you want to save the items, Muhammad Abrar's answer will do –  chechopeefe Feb 9 '12 at 23:54
