Search and Retrieve specific value from Array

PHP
1

I have an array output results in this format

Array ( [0] => stdClass Object ( [ID] => 8 [Value] => 7 ) [1] => stdClass Object ( [ID] => 9 [Value] => 8 ) [2] => stdClass Object ( [ID] => 10 [Value] => 7 ) [3] => stdClass Object ( [ID] => 11 [Value] => 7 ) [4] => stdClass Object ( [ID] => 12 [Value] => 6 ) [5] => stdClass Object ( [ID] => 13 [Value] => 9 ) [6] => stdClass Object ( [ID] => 14 [Value] => 5 ) [7] => stdClass Object ( [ID] => 15 [Value] => 7 ) [8] => stdClass Object ( [ID] => 16 [Value] => 7 ) [9] => stdClass Object ( [ID] => 17 [Value] => 3 ) [10] => stdClass Object ( [ID] => 18 [Value] => 5 ) )

Now I would like to search the array for a specific ID and retrieve its associated value.

For example say $searchID = 13. So search the arrary for ID 13 and should return the result of Value as 9.

I have tried multiple solutions but each time results in null value which means I am doing something wrong.

I can simply print a specific array value like this $outputarray[5]->Value which would output the array to me. But any way to search and retrieve values as per above array?
Any help is highly appreciated.

Thanks

Ok this is the solution that worked for me

$arrayval = here the array comes;
$id = X the value you wish to search for ID;

foreach($arrayval as $item){
        if ($item->ID == $id)
            return $item->Value;
    }
    return "not found";
}

I have just been playing and discovered:


<?php 

$arrayVal = array
( 
  8  => 7,
  9  => 8,
  10 => 7,
  11 => 7,
  12 => 6,
  13 => 9,
  14 => 5,
  15 => 7,
  16 => 7,
  17 => 3,
  18 => 5,
);

$obj2 = new stdClass(); // on-the-fly!
  $obj2->{8}  = 7;
  $obj2->{9}  = 8;
  $obj2->{10} = 7;
  $obj2->{11} = 7;
  $obj2->{12} = 6;
  $obj2->{13} = 9;
  $obj2->{14} = 5;
  $obj2->{15} = 7;
  $obj2->{16} = 7;
  $obj2->{17} = 3;
  $obj2->{18} = 5;

$id = 13;
echo '<pre>';
  echo '$arrayVal = ';
    print_r($arrayVal); 
    echo 'function getIdFromObject( $id, $arrayVal)<br />';
    echo 'result = ' .getIdFromObject( $id, $arrayVal );
    echo '<br /><br /><br />';

  echo '$obj2 = ';
    print_r($obj2); 
    echo 'getIdFromObject( $id, $obj2 )<br />';
    echo 'result = ' .getIdFromObject( $id, $obj2 );
    echo '<br /><br /><br />';
    
    $obj = (object) $arrayVal;
  echo '$obj = ';
    print_r($obj); 
    echo 'getIdFromObject( $id, $obj  )<br />';
    echo 'result = ' .getIdFromObject( $id, $obj ); 
echo '</pre>';

function getIdFromObject( $id, $objArray )
{
  $result = 'cannot find $id = ' .$id;

  // accepts both Obj AND arrays 
  foreach( $objArray as $key => $value )
  {
    if ($key == $id):
      $result = 'Found $id = ' .$value;
    endif;  
  }
  return $result;
}

Output:

$arrayVal = Array
(
[8] => 7
[9] => 8
[10] => 7
[11] => 7
[12] => 6
[13] => 9
[14] => 5
[15] => 7
[16] => 7
[17] => 3
[18] => 5
)
function getIdFromObject( $id, $arrayVal)
result = Found $id = 9

$obj2 = stdClass Object
(
[8] => 7
[9] => 8
[10] => 7
[11] => 7
[12] => 6
[13] => 9
[14] => 5
[15] => 7
[16] => 7
[17] => 3
[18] => 5
)
getIdFromObject( $id, $obj2 )
result = Found $id = 9

$obj = stdClass Object
(
[8] => 7
[9] => 8
[10] => 7
[11] => 7
[12] => 6
[13] => 9
[14] => 5
[15] => 7
[16] => 7
[17] => 3
[18] => 5
)
getIdFromObject( $id, $obj )
result = Found $id = 9

Ok I think @John_Betong would work great as we simply create a function which could handle both the arrays as well as object arrays. Great solution. Thanks for the help
