small array problem

[pedrobcabral]

<?php
$i =  array();
while($row = mysql_fetch_array($result)){
$i[$x] = $row['id'];
$x++;
}

echo "<pre>";
print_r($i);
echo "</pre>";
?>

 

This outputs the folowing:

 

Array

(

    [] => 3

    [1] => 4

    [2] => 9

)

 

Why the first it is not [ 0 ] ? Can't figure out the way to turn it that way. Thank you.

The variable $x is not set during the first iteration of the loop. A better way to write this would be:

<?php
$i =  array();
while($row = mysql_fetch_array($result))
      $i[] = $row['id'];
?>

 

When you use "[]" with arrays, PHP assigns the value to the next numerical array index automatically. This will give you what you want.
