PHP：数组匹配问题

i have array1 with following content

array(
'banana',
'apple',
'orange');

and i have a different associative array2 with content and prices of items

array('banana'  => '1.45',
'apple'   => '2.99',
'carrot'  => '1.99',
'orange'  => '0.99',
'papaya'  => '2.99');

how do i generate a final array, that combines the two, with their common parts, that i get this final result:

   array('banana'  => '1.45',
  'apple'   => '2.99',
  'orange'  => '0.99');

You can do this:

$fruitNames = array(
'banana',
'apple',
'orange');

$fruitValues = array('banana'  => '1.45',
  'apple'   => '2.99',
  'orange'  => '0.99');



$finalArray = array();

foreach($fruitNames as $value)
{
    $finalArray[$value] = $fruitValues[$value];
}

$finalArray will have the expected value.

I would use array_intersect_key() here.

$intersection = array_intersect_key($second, array_flip($first));

CodePad.

use array_key_exists to loop thru and make new array
