php question

in the code bellow every time my page is loaded $src becomes a random number. is it possible to incresse $src by one somehow ? so if it become 45 i want it to be incressed by one to 46.

<? echo "/flash/loops/".basename($src).""; ?>

 

how /where you initialize that $src variable ? is that global ?

 

check the script bellow. it's a randomizing script a friend gave me. i want $src to become +1 and one place only the rest of the places it's displayed should stay the same number

/* The default folder with images */
$settings['img_folder'] = '/var/www/flash/loops/';
/* File types (extensions) to display */
$settings['img_ext'] = array('.jpg','.gif','.png','.swf');

$settings['display_type'] = 0;

/* Allow on-the-fly settings override? 0 = NO, 1 = YES */
$settings['allow_otf'] = 1;

/* Override type? */
if ($settings['allow_otf'] && isset($_GET['type']))
{
	$type = intval($_GET['type']);
}
else
{
	$type = $settings['display_type'];
}

/* Override images folder? */
if ($settings['allow_otf'] && isset($_GET['folder']))
{
	$folder = htmlspecialchars(trim($_GET['folder']));
    if (!is_dir($folder))
    {
    	$folder = $settings['img_folder'];
    }
}
else
{
	$folder = $settings['img_folder'];
}

/* Make sure images fodler ends with an '/' */
if (substr($folder,-1) != '/')
{
	$folder.='/';
}

/* Get a list of all the image files */
$flist = array();
foreach($settings['img_ext'] as $ext)
{
    $tmp = glob($folder.'*'.$ext);
    if (is_array($tmp))
    {
    	$flist = array_merge($flist,$tmp);
    }
}

/* If we have any images choose a random one, otherwise select the "noimg.gif" image */
if (count($flist))
{
	$src = $flist[array_rand($flist)];
}
else
{
	$src = 'noimg.gif';
}

/* Output the image according to the selected type */
if ($type)
{
	header('Location:'.$src);
    exit();
}
else
{   
    $fruit   = array('apple', 'pear');
    $text    = 'a p';
    $output  = str_replace($letters, $fruit, $text);

}
?>

<? echo "/flash/loops/".basename($src).""; ?>

Code (markup):

 

Replace $src = $flist[array_rand($flist)];

with

$src = $flist[array_rand($flist) + 1];

I don't know why you'd want to do that, though.

 

ah sorry let me remake the question. let's say i have this

<? echo "/flash/loops/".basename($src).""; ?> and once the page load $src becomes 55. i want to have another link like this <a href="<? echo "/flash/loops/".basename($plus).""; ?>">next</a> <-- that one should have the +1 to it, so it's 56 insteed.

 

Simply just add 1 (google "php addition operator") to $src.

Heres a quick example

<?php
$basename = basename($src);
$next = $basename + 1;
?>
<a href="<?php echo "/flash/loops/".$next; ?>">next</a>
