通过索引访问PHP字符串数组

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] ?

Answer 1

Use array_values()

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

Manual: http://php.net/manual/en/function.array-values.php

Answer 2

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

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

Answer 3

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

   foreach($arr as $value){

       $data[$i] = $value;

       $i++;

    }

    print_r($data);
