How to choose the first element? $ array [0] does not work …

Answer 1, Authority 100%

If you need to get the value of the first element of the array, without knowing its key, you can use the array_shift () but not always convenient because this element, it seems to cut out of the array:

$ array = array ();
$ Array [Key] = 'Val';
$ array [Keya] = 'val1';
$ array [keyb] = 'val2';
$ first = array_shift ($ array);
Echo $ First; // Val.
Print_R ($ array); // What remains in the array
Array.
(
  [KEYA] = & GT; Val1.
  [KeyB] = & gt; Val2.
)

The second way is to use the CURRENT

$ array = array ();
$ Array [Key] = 'Val';
$ array [Keya] = 'val1';
$ array [keyb] = 'val2';
// Reset ($ array); // You can use for complete confidence that the pointer will be on the first element of the array (not fundamentally)
Echo Current ($ Array); // Val.

The fastest way without any modification of the source array:

foreach ($ array as $ element) break;

$ element now contains the first array element $ Array

Answer 4

foreach ($ array as $ key = & gt; $ value) {
  $ FirstIndex = $ Array [$ Key];
  Break;
}

Answer 5

echo $ array [Key];
