array issues starting at 1 not 0

jannoy

to all php gurus

how can i store data into array which will start immediately at storage 1 not storage 0

here is the simpliest code

$string="hello,world,im, new, here";

$split=explode(",",$string);

where $split[1] =="hello" not "world"

And here is the original code

----------- entry.php--------
<body>
<form name="formmenu" method="post" action="">
<table width="425" height="117" border="1" align="center">
<tr>
<td width="415">
<textarea name="topmenu" cols="50" rows="2"></textarea> </td>
</tr>
<tr>
<td>
<input name="Submit" type="submit" onClick="MM_openBrWindow('menuoutput.php?topmenu='+ window.formmenu.topmenu.value ,'menureview','width=400,height=400');return false;" value="Submit"> </td>
</tr>

--- menuoutput.php -----------
$topmenu=$_GET['topmenu'];
$split=explode(",",$topmenu);
$numtopmenu=count($split);

Why do you need it starting at 1? It is easier to handle arrays if they begin at 0, believe me. If you are tying to, say, display the number beside like this
1. here
2. is
3. a list
You can do it like this

<?php
$array=array('here','is','a list');
for($i=0;$i<count($array);$i++) {
  echo(($i+1).$array[$i]."<br />\n");
}
?>

or you could use my reindex() function:

$array = reindex(explode(',', $str), 1);

easy as that.

function reindex($in, $startat = 0)
{
    $num = array();
    $hash = array();
    $out = array();
    ksort($in);
    foreach ($in as $key => $val)
    {
        if (ctype_digit($key))
        {
            $num[(int)$key] = $val;
            continue;
        }
        else
        {
            $hash[(string)$key] = $val;\
            continue;
        }
    }
    //now that we have them seperated...

//reindex the numerical side of things
$num_keys = array_keys($num);
for ($i = $startat, $j=0; $i < count($num); $i++, $j++)
{
    //we need both i and j because of the (potentially) different numbering schemes (which is why there's this function)
    $out[$i] = $num[$num_keys[$j]];
}

//we don't need much for the hash side of things..
ksort($hash);
$out = array_merge($out, $hash);
//now the pieces with hash indices alphabetically sorted at the end of the array
return $out;
}

$array = array_merge(array(''),array_values($array));
unset($array[0]);

But I agree with bubblenut; why ignore decades of programming experience?

thank u guy for ur response. The input in my textarea will be use as menus which is done in javascripting. The sub menus will not accept [0] layer in array output it will accept immediately at [1] layer

I tried out your code and this is my result

$string="hello,world,im, new, here"; 


$split=explode(",",$string); 

foreach($split as $va => $re){
	echo $va ."----". $re."<BR>";
}

RESULT

0----hello
1----world
2----im
3---- new
4---- here
