inserting values into a php array using for loop and condition

I wanted to insert values into a php array using conditions like the way below but it is not happening please let me know if there are any other ways to do that!

$noarray=array();
for ($i=1; $i<=10 ;$i++)
{
$noarray[]=$i;
echo $noarray[$i];
echo"<br/>";
}


**but its giving "Undefined offset" error!!

Answer

You are adding $i as a value in the $noarray array.

So is you take step by step, when $i == 1 (first step in for) you will add in the first element of array value of the $i (1). Because in php index starts from 0 you will have an array like this: [0 => 1] with only one element. At this step you try to access the array by index $i = 1, but you have only at index 0 value.

I don't know exactly what you try to do, but you mess with index and value.

Probably you want something like this:

$noarray=array();
for ($i=1; $i<=10 ;$i++)
    {
        $noarray[$i] = $i;
        echo $noarray[$i];
        echo"<br/>";       
    }

This way you specify at index $i to add value $i. You can change this if you want.
