[SOLVED] Loop

[burnside]

Hey all,

 

Got a little problem, I have the code below :

 

<?php

  foreach (range('0000','9999') as $num) {

    echo "  $num <br />";
  }
?>

 

Work's but hasnt done what i expected it to do,

 

what i want is for it to loop through :

 

0001

0002

0003

 

9998

9999

 

etc ... ... but it doesnt it starts at 1 and not 0001 any one got any ideas?

Range expects integers, so it will convert them. Just pad the 0s on when you print:

 

<?php
  foreach(range(0,9999) as $num){
    echo "  ".str_pad($num,4,'0',STR_PAD_LEFT)." <br />";
  }
?>

Haha thanks that works great,

 

is there a way to cound how many times it loped through? i would use count but it's not in a database haha

Well, if it always starts at 0, it will be $num + 1 once it's done:

<?php
  foreach(range(0,9999) as $num){
    echo "  ".str_pad($num,4,'0',STR_PAD_LEFT)." <br />";
  }
  echo "It ran ".($num + 1)." times";
?>

 

if you don't know...just use a counter:

<?php
  $i = 0;
  foreach(range(0,9999) as $num){
    echo "  ".str_pad($num,4,'0',STR_PAD_LEFT)." <br />";
    $i++;
  }
  echo "It ran $i times";
?>
