Question 42192 in PHP Question posted in
Official manual can be found here.

PHP Displaying an array_filtered result using foreach seems wrong – Is there a less dirty way?

We have an array of pets, with name and species defined.

$dogs = array_filter($pets, 
    fn($v) => $v["species"]=="Dog");

foreach($dogs as $row) echo $row["name"];

The foreach to display the result seems so wrong after such a beautiful arrow function.

Am I missing something?

    foreach(array_filter($pets, 
    fn($v) => $v["species"]=="Dog") as $row) echo $row["name"];

    or, replacing the foreach loop with implode() and array_column():

    echo implode(", ", 
        array_column(
            array_filter($pets, fn($v) => $v["species"]=="Dog"), 
            "name")
    );

    The latter would I guess be more strictly functional.

    <?php

    $pets = array(
        array('name'=>'Jack', 'species'=>'Dog'),
        array('name'=>'Jina', 'species'=>'Cat')
     );

     function select_dog($var)
     {
        return $var["species"]=="Dog";
     }

    $dogs = array_filter($pets, 'select_dog');

    foreach($dogs as $row) echo $row["name"]

?>
