Php: how to get associative array with numeric index?

Question

If I have:

$array = array( 'one' =>'value', 'two' => 'value2' ); 

how do i get the string one back from $array[1] ?

Answer 1

No. There is no key in your array [1] . You could:

• Create a new array containing the keys:

   $newArray = array_keys($array); echo $newArray[0]; 

  But the value of "one" is in $newArray[0] , not [1] .
  Label:

   echo current(array_keys($array)); 

• Get the first key of the array:

    reset($array); echo key($array); 

• Get the key corresponding to the value "value":

   echo array_search('value', $array); 

It all depends on what exactly you want to do. The fact is that [1] does not correspond to “one” to any in which direction you turn it on.

Answer 2

 $array = array( 'one' =>'value', 'two' => 'value2' ); $allKeys = array_keys($array); echo $allKeys[0]; 

It will display:

 one 

Answer 3

If you plan to work with only one key, you can do this with a single line without having to store an array for all keys:

 echo array_keys($array)[$i]; 

Answer 4

Or if you need it in a loop

 foreach ($array as $key => $value) { echo $key . ':' . $value . "\n"; } //Result: //one:value //two:value2 

Answer 5

 $array = array( 'one' =>'value', 'two' => 'value2' ); $keys = array_keys($array); echo $keys[0]; // one echo $keys[1]; // two 

Answer 6

You can do it as follows:

 function asoccArrayValueWithNumKey(&$arr, $key) { if (!(count($arr) > $key)) return false; reset($array); $aux = -1; $found = false; while (($auxKey = key($array)) && !$found) { $aux++; $found = ($aux == $key); } if ($found) return $array[$auxKey]; else return false; } $val = asoccArrayValueWithNumKey($array, 0); $val = asoccArrayValueWithNumKey($array, 1); etc... 

I haven't tried the code, but I'm sure it will work.

Good luck

Answer 7

key function helped me and is very simple

Answer 8

Expanding in response to Ram Dan, the key function is an alternative way to get the key of the current array index. You can create the following function,

  function get_key($array, $index){ $idx=0; while($idx!=$index && next($array)) $idx++; if($idx==$index) return key($array); else return ''; }
