while to foreach array

Just a quick and simple snippet, im sure most of you know this one but for those who dont, enjoy.

PHP Code:


		
			
<?php

     while($row = mysql_fetch_array( $result )) {

        $new=$row['fieldname'];

        $new_array[] = $new; 

     } 

      

     foreach($new_array as $key => $value) {

        echo $key. " - " . $value . "<br />";

     }

?>

This will print out something similar to:

0 - result0
1 - result1
2 - result2
3 - result3
4 - result4

etc....
5 - result5

But why do you need the second loop? You could use a counter variable, and increment it inside the first while loop to print the index.

like this

PHP Code:


		
			
$i=0;
while($row = mysql_fetch_array( $result )) {
       echo $i. " - " . $row['fieldname'] . "<br />";
      $i++;
     }
