Hi,

Please tell me what you think will happen if I run:

function sesid()
            {
                for($i=0; $i++; $i<8)
                {
                $num = rand(1,9);
                $sesid .= $num;
                }
            }
            
            sesid(); 

I know what SHOULD happen but I don't think it's working.

Thanks.

Cant see anything wrong with it. I ran it and i get a number between 1 and 9. so it works

function sesid(  )
{

    for( $i = 0; $i < 8; $i++ )
    {
    
        $num = rand( 1,9 );
        $sesid .= $num;
        
    }
    
    return $sesid;

}

$id = sesid(  );

You're supposed to get an 8 digit number haha.

function sesid(  )
{

    for( $i = 0; $i < 8; $i++ )
    {
    
        $num = rand( 1,9 );
        $sesid .= $num;
        
    }
    
    return $sesid;

}

$id = sesid(  ); 

Works like a charm, thanks very much. +rep

If you're trying to get an eight digit number why not do-

rand( "10000000", "99999999" );

If you're trying to get an eight digit number why not do-

rand( "10000000", "99999999" );

That'd be the better method.

function sesid(  )
{

    for( $i = 0; $i < 8; $i++ )
    {
    
        $num = rand( 1,9 );
        $sesid .= $num;
        
    }
    
    return $sesid;

}

$id = sesid(  ); 

Ah well as long as it works it's fine. Like the wires at the back of my computer, messy, but works great

For loops are a lot slower than Toms method. Your logic is... interesting.

[iUnknown]

Haha fine, I'll test it and use it.

$id = rand( "10000000", "99999999" ); 
$sesid = $id; 

works like a charm would +rep Tom but gotta spread.

If you're trying to get an eight digit number why not do-

rand( "10000000", "99999999" );

Why are you using strings on a number randomiser?
