$array1 = array(0=>array('mac'=>'mac0','geo'=>'geo0'),1=>array('mac'=>'mac1','geo'=>'geo1'), 2=>array('mac'=>'mac2','geo'=>'geo2')...);   $array2 = array(0=>array('id'=>'id0','gname'=>'gname0'),1=>array('id'=>'id1','gname'=>'gname1'), 2=>array('id'=>'id2','gname'=>'gname2')...);

i want compare 2 arrays first array value mac , second array value gname

not update

for example if value of array available in array in array2 update

else not update

here wrote code: 

    $array1 = array(0=>array('mac'=>'mac0','geo'=>'geo0'),1=>array('mac'=>'mac1','geo'=>'geo1'), 2=>array('mac'=>'mac2','geo'=>'geo2'));   $array2 = array(0=>array('id'=>'id0','gname'=>'gname0'),1=>array('id'=>'id1','gname'=>'gname1'), 2=>array('id'=>'id2','gname'=>'gname2'));  function gluearray($ar1, $ar2) {     foreach($ar2 $key=>$value) {         if(isset($ar1[$key])) {             if(is_array($ar1[$key])) {                 $ar1[$key] = gluearray($ar1[$key], $value);             } else {                 if($ar1[$key]!==$value) {                     $ar1[$key] = $value;                 }             }         } else {             $ar1[$key] = $value;         }     }     return $ar1; } print_r(gluearray($array1, $array2));

result:

array ( [0] => array ( [mac] => mac0 [geo] => geo0 [id] => id0 [gname] => gname0 ) [1] => array ( [mac] => mac1 [geo] => geo1 [id] => id1 [gname] => gname1 ) [2] => array ( [mac] => mac2 [geo] => geo2 [id] => id2 [gname] => gname2 ) )
