if you want to change the array in foreach by changing the $value at above code it should be pass by reference

so foreach($product as $key=>&$value)

here &$value means its not passing value of the array but passing associated refrence

so need code will be like 


$products=array("Iphone","Samsung Galaxy","Google Pixel"); 
 
foreach($products as $key=>&$value)
{
      $value=  $key."-".$value
}
print_r($products);


result will be
Array("1-Iphone","2-Samsung Galaxy","3-Google Pixel")

$products=array("Iphone","Samsung Galaxy","Google Pixel"); 

foreach($products as $key=>&$value)
{
      $products[$key]=  $key."-".$value;
}
print_r($products);

use direct array name with index and you can change value direct in loop
result 

Array ( [0] => 0-Iphone [1] => 1-Samsung Galaxy [2] => 2-Google Pixel )
