PHP foreach and associative arrays |

In C#, we do foeach function in this way..

foreach (string s in strArray) {
    Console.WriteLine(s);  // whatever print statement depending your platform..

}

which is quite straightforward to me.

and in PHP, we do this..

$things = array("this", "that", "those");
foreach ($things as $get) {
    echo "$get<br />";
}

so it’s actually backwards in order of C#, and it’s not as clear as C#, but I think I can get used to it.

And it gets more interesting with..

$smartphones = array("apple" => "iphone", "samsung" => "galaxy9", "lg" => "v30");
foreach ($smartphones as $key => $value ) {
    echo "$key = $value<br />";
}

These are called associative arrays, which are like map in java and dictionary in Python.

There are two ways initializing associative arrays in PHP.

One is to set

$ages = array("jim" => "13", "michelle" => "22", "jane" => "18");

$age['Peter'] = "32";
$age['Ben']  = "12";
$age['Jim']  = "22";
