How to create integer out of array?

Is it possible to convert array values into one single integer. For example, I have array with numbers

$array = array(7,4,7,2);

Is it possible to get integer value 7472 from this array?

Use implode, along with (int) to convert the string result to an integer:

$a = [7,4,7,2];
$res = (int) implode('', $a);

P.S. Since PHP 5.4 you can also use the short array syntax, which replaces array() with [].

function digitsToInt($array) {
  $nn = 0;
  foreach ( $array as $digit) {
    $nn = $nn * 10 + intval($digit);
  }
  return $nn;
}
var_dump( digitsToInt(array(7,4,7,2)) ); # int(7472)

Use implode, which creates a string from an array. http://php.net/manual/en/function.implode.php

echo implode($array);
