This tutorial shows how to get each character separately from a number, in PHP.
The main thing is to convert the number into a string (with (string) ), then you can get each character using its index.
- Example:
<?php
$nr = 15674789;
$nr_str = (string) $nr;    // convert $nr into a string

echo $nr_str[0];              // 1
echo '<br/>'. $nr_str[2];     // 6      

$nr_ln = strlen($nr);     // gets the number of characters in $nr

// output the number of characters in $nr, and the last character
echo '<br/>'. $nr_ln;                   // 8
echo '<br/>'. $nr_str[$nr_ln - 1];      // 9
?>

• If you want to hold each number separately into an array, use: str_split($number, 1).
- Example:
<?php
$nr = 15674789;
$nr_arr = str_split($nr, 1);

echo $nr_arr[0];              // 1
echo '<br/>'. $nr_arr[2]. '<br/>';     // 6

// output the entire array
var_export($nr_arr);
  // array ( 0 => '1', 1 => '5', 2 => '6', 3 => '7', 4 => '4', 5 => '7', 6 => '8', 7 => '9', )
?>
