Changing value inside foreach loop doesn't change value in the array being iterated over

Question

Why does this yield this:

foreach( $store as $key => $value){
$value = $value.\".txt.gz\";
}

unset($value);

print_r ($store);

Array
(
[1] => 101Phon         


        

Answer 1

Try

$catalog = array();

foreach( $store as $key => $value){
    $catalog[] = $value.".txt.gz";
}


print_r ($catalog);

OR

foreach( $store as $key => $value){
    $store[$key] = $value.".txt.gz";
}


print_r ($store);

Depends on what you want to achieve

Thanks :)
