我怎样才能在Array中搜索值？

Question

I have an array like this and i m trying to search a value using this array:

$arr = Array('Slovenly Mexico','Slovenly Europe','Greece');

I am using such kind of condition. please help

if($a[storename] == $arr[$i]){
                //some code

          }

but it is not working because it searches as index value so it gives an error.

Array
(
    [0] => Array
        (                    
            [storename] => Greece
        )

    [1] => Array
        (         
            [storename] => Slovenly Europe
        )


    [3] => Array
        (           
            [storename] => Slovenly Europe
        )

    [4] => Array
        (       
           [storename] => Greece
        )

    [5] => Array
        (
        [storename] => Slovenly Mexico

        )

    [6] => Array
        (
            [storename] => Slovenly Europe
        )

    [7] => Array
        (
         [storename] => Slovenly Mexico

        )
 } 

Answer 1

you can use in_array()

eg.,

$sizeofarray=sizeof($a);
for($i=0;$i<sizeofarray;$i++)
{
   if(in_array($a[$i][storename],$arr)) 
   {
       echo "Found";
       break;
   }
   else
       echo "Not found";
}
