undefined offset help

[ashy]

Hi All,

 

I kept getting undefined offset PHP notice for a simple for loop. For eg

$va = array();

$i=0;

while($row = mysql_fetch_array($result))

{

  $va[$i] = $row['id'];

  $i++;

}

It gives undefined offset at this line $++

 

thanks

a.) that's not a for loop thats a while loop.

b.) you don't have $++ in your code you have $i++ (but thats probably just a typo)

c.) since $va is an array, you don't really need the $i variable at all.

 

$va = array();
while($row = mysql_fetch_array($result)) {
   $va[] = $row['id'];
}

d.) you are getting undefined offset because you are attempting to access an item in the array that doesn't exist.
