PHP - Replace values in an array

Question

I have an array of english colors and I want to translate some of them to frensh, I didn't find a standard PHP function to replace some value of an array with other, So I wrote my own but I'm looking for a simpler way if there is!

I'm looping through the englishColors array and checking if there is the colors that I want to replace with frensh colors.

$englishColors = array("Black","Green","Red");
$frenshColors = array();
foreach ($englishColors as $color) {
 if ($color == "Black") {
 $frenshColors[] = "Noire";
 continue;
 }elseif ($color == "Red") {
 $frenshColors[] = "Rouge";
 continue;
 }
 $frenshColors[] = $color;
}
var_dump($frenshColors);

Answer 1

Use an array. In the index you write the english name, the value the french name.

$arrayAux = [
 'red' => 'rouge',
 'black' => 'noir',
];

Then, when you want the array with the french colors:

$frenshColors = array();
foreach ($englishColors as $color) {
 if (array_key_exists($color, $arrayAux)) {
 $frenshColors[] = $arrayAux[$color];
 } else {
 $frenshColors[] = $color;
 } 
}

• Nigel Ren: If you use $arrayAux[$color] ?? $color, then if the color isn't found, it will store the original color.
• MR Mark II: I edit, but I choose dont save any color if the key doesnt exist. But its a good idea, or save any other value.
• Nigel Ren: In the original code, they have $frenshColors[] = $color; which is doing the same thing - if there isn't a translation then store the original.
• MR Mark II: Oh, its true, i didnt see it. Thanks!

Maybe use a hash-table kind of array?

$colors = [
 "Black" => "Noire",
 "Green" => "?",
 "Red" => "Rouge",
];
echo $colors["Black"]; // Noire

Then if you want to the opposite, you can:

$colors = array_flip($colors);
echo $colors["Noire"]; // Black

if you only want to replace values in an array use: array_replace
