Question

Array
       (
           [0         


        

Answer 1

Something like that :

function getIndex($array, $slabId) {
    foreach($array as $index => $item) {
        if($item->slabId == $slabId)
            return $index;
    }
}

Answer 2

I will suggest, change your Data Structure

• use slabId as Array_Index

• Eg.

  Array

  (

     [0] => NULL
  
     [1] => incentiveSlab Object
         (
             [slabId] => 1
             [templateId] => 1
             [startPoint] => 0
             [endPoint] => 1000000
             [value] => 0
         )
  
     [2] => incentiveSlab Object
         (
             [slabId] => 2
             [templateId] => 1
             [startPoint] => 1000000
             [endPoint] => 2500000
             [value] => 0.5
         )
  

  )

Or if you have too much variance in slabId use Associative Array

Answer 3

The solution should return the index if it is found like the above answers. However, it should returns something else if there is no match, like other standard functions such as substr which returns false if there is no match. so Max answer may be modified, slightly, to be:

function getIndex($array, $slabId) {
    foreach($array as $index => $item) {
        if($item->slabId == $slabId)
            return $index;
    }
    return false; // or return -1
}
