Access PHP array of strings by index

Question

I have a PHP array like

$arr = array("c_m_email" => "[email protected]");

and I can access the email by

$arr['c_m_email']

But is there another way to just write $arr[0]?

No, an array value has one key and that is the only key you can use. — jeroen

If you want to use [0] than you have to edit that array and set index from [c_m_email] to [0]. Otherwise you have to use [c_m_email]. — Ankesh Vaishnav

All those comments aren't true! Use array_values() as modsfabio said in the answer below and you can access the elements by their index. — Marten

Use array_values()

array_values() returns all the values from the array and indexes the array numerically.

If you want the first entry in the array, you could also do this:

reset($h);
echo current($h)

    $i=0;
    $data=array();

   foreach($arr as $value){

       $data[$i] = $value;

       $i++;

    }

    print_r($data);

This is exactly what the PHP function array_values() does. So, why would you write the code for that by yourself?

Thank you for this code snippet, which may provide some immediate help. A proper explanation would greatly improve its educational value by showing why this is a good solution to the problem, and would make it more useful to future readers with similar, but not identical, questions. Please edit your answer to add explanation, and give an indication of what limitations and assumptions apply.
