Access PHP array of strings by index

Question

I have a PHP array like

$arr = array("c_m_email" => "a@b.z");

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, Jun 28 '17 at 12:34

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, Jun 28 '17 at 12:58
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, Jun 28 '17 at 13:05

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? – Marten Jun 28 '17 at 14:49
Thank you for this code snippet, which may provide some immediate help. A proper explanation [would greatly improve](//meta.stackexchange.com/q/114762) 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. – Toby Speight Jun 28 '17 at 15:52
