PHP comparar dos matrices y obtener los valores coincidentes no la diferencia
Estoy tratando de comparar dos matrices y obtener solo los valores que existen en ambas matrices, pero, desafortunadamente, no puedo encontrar la función de matriz correcta para usar...
Encontré la función array_diff()
: http://php.net/manual/en/function.array-diff.php
Pero es por la diferencia de los dos arrays.
Ejemplo:
$array1 = array("**alpha**","omega","**bravo**","**charlie**","**delta**","**foxfrot**");
$array2 = array("**alpha**","gamma","**bravo**","x-ray","**charlie**","**delta**","halo","eagle","**foxfrot**");
Producto previsto:
$result = array("**alpha**","**bravo**","**charlie**","**delta**","**foxfrot**");

Simple, use array_intersect()
en su lugar:
$result = array_intersect($array1, $array2);

OK.. Necesitábamos comparar un número dinámico de nombres de productos...
Probablemente hay una mejor manera... pero esto funciona para mí...
... porque....Las cadenas son solo matrices de caracteres.... :>}
// Compare Strings ... Return Matching Text and Differences with Product IDs...
// From MySql...
$productID1 = 'abc123';
$productName1 = "EcoPlus Premio Jet 600";
$productID2 = 'xyz789';
$productName2 = "EcoPlus Premio Jet 800";
$ProductNames = array(
$productID1 => $productName1,
$productID2 => $productName2
);
function compareNames($ProductNames){
// Convert NameStrings to Arrays...
foreach($ProductNames as $id => $product_name){
$Package1[$id] = explode(" ",$product_name);
}
// Get Matching Text...
$Matching = call_user_func_array('array_intersect', $Package1 );
$MatchingText = implode(" ",$Matching);
// Get Different Text...
foreach($Package1 as $id => $product_name_chunks){
$Package2 = array($product_name_chunks,$Matching);
$diff = call_user_func_array('array_diff', $Package2 );
$DifferentText[$id] = trim(implode(" ", $diff));
}
$results[$MatchingText] = $DifferentText;
return $results;
}
$Results = compareNames($ProductNames);
print_r($Results);
// Gives us this...
[EcoPlus Premio Jet]
[abc123] => 600
[xyz789] => 800
