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

pass $value as a reference:

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